H: transÂlucent, semi wax-like inclusions in sample III (field of view 16 mm). Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, Vol. The surface of HT beeswax is slowly oxidized during the heat treatment, and the color may reach chicken-fat yellow. However, amber can be found in geological environments with high pressure (for example, the surrounding rock of amber in the Baltic Sea was mainly a blue mud layer). Figure 17. Chronicles the history of this cultural landmark, originally assembled for the Prussian king between 1701 and 1714, and its reconstruction by the Soviet Union starting in 1979. There is an obvious layering of different-sized and different-colored bubbles near the surface of roasted HT amber (figure 9I). Aromatic amber is also know by the names: India Amber, Himalayan Amber, Omber, Ambergris (pseudo). F: residual stress cracks along the oval bubbles. This makes beeswax candles great for … Different-sized pores and newly grown brown or yellowish white crust-like skin appear locally on the surface of the rough amber. A: sample I (golden amber, 10.20 g). G: densely distributed HT spots along the white belt. Amber resin can be used as perfume by dabbing a small amount onto your skin or dark clothing such as jeans (as it may stain or leave a mark otherwise). Dab or smear a small amount onto your wrists, allowing your body heat to melt the amber, then rub your wrists together until amber is no longer visible. Three amber samples before and after hydrothermal treatment were measured using a Bruker Tensor-27 Fourier transform infrared (FTIR) spectrometer to check the variations among the functional groups of samples. Amber Resin is delightfully aromatic intoxicating the senses with it's wonderfully rich scent. The corresponding absorption peaks at 1457 and 1378 cmâ1 are attributed to δ (CH2-CH3) bending vibration and carbonyl stretching vibration absorption peaks ranging from 1695 to 1736 cmâ1. Zhang P.L. At just $20, it’s an excellent alternative to Diptyque’s popular Ambre candle. Each has their own secret recipe which is handed down through the generations and is guarded as a family trade secret. Hydrothermal treatment followed by heat treatment can produce beeswax with a âchicken-fat yellowâ color (figure 1D). Roasted old beeswax: white or light yellow beeswax that is heat-treated to enhance the color to a dark or saturated yellow (figure A-2B). This research was financially supported by Grant No. It is recommended that you use half the amount of candelilla wax as beeswax since it has twice the stiffening powers. Morphological analysis was carried out via optical microscopy (Olympus BX 60) and scanning electron microscopy (FEI Inspector-F) with an electron beam of 20 kV. Because of it's divine fragrance, it has been considered as a sacred temple powder often referred to as "Nectar of the Gods" or "Ambrosia". IdentiÂfication focuses on external and internal characteristics (figure 17): Hydrothermal treatment can be used to improve the appearance of amber materials (from transparent to opaque) to cater to Chinese consumers. In addition to providing color to the wood, hard-wax oil finishes keep it from drying out over time, protecting against warping and weakening. CUG170677). HT Amber Quality and Durability. First of all, amber in the furnace will be affected by the dual role of temperature and pressure, resulting in softening (making it rubbery). Figure 3. Beijing Traditional Chinese Medicine, Vol. Natural Amber Beeswax Raw Stone Insect Display Scorpion - Butterfly - Cicada - Dragonfly StoneHandiCraftDe. Amber Lights Candles uses only 100% cotton wicks. SEM images of (C) natural white beeswax and (D) crust of HT white beeswax. Characterization of âGreen Amberâ With Infrared and Nuclear Magnetic Resonance Spectroscopy. Microscopic Characteristics of Finished HT Amber. Hair: Because of its waxy texture, beeswax works well in hair products like pomades, moustache waxes, and beard balms. Gemological characteristics of rough amber specimens before hydrothermal treatment. After treatment, the inner layer of the weathered skin of rough amber material will generate a layer of yellowish white or greenish yellow HT skin of various thicknesses, or a corrugated crust containing pores. Journal of Gems and Gemmology, Vol. A: yellowish green HT skin. As a result, the treated amber exhibits a uniform and compact appearance, and these commercial products are commonly known as hydrothermally treated or âHTâ amber. It looks like ear wax and has the consistency of coconut oil meaning; it’s not hard enough to be considered a solid. G: infrared absorbance before and after hydrothermal treatment. Yamei Wang, Yan Li, Fen Liu, Fangli Liu, and Quanli Chen. 16–22 (in Chinese with English abstract). Use caution when placing amber in warm or hot environments. In our experiment, the three samples changed from transparent to translucent or opaque after hydrothermal treatment, achieving the expectation of treatment (see the characteristics in table 2). Specimens. In recent years, Chinese amber manufacturers have gradually mastered hydrothermal treatment through continuous exploration and technology transfer. A series of processes take place during the formation of amber from resinite. In the present work, the authors studied the inclusions and IR spectra of the specimens before and after hydrothermal treatment, providing valuable information regarding the formation mechanisms and identification characteristics of HT amber. Explore amber history, research, quality factors, and more in the GIA Gem Encyclopedia. For more information on shellac write to us or ask your ZINSSER dealer for a copy of The Story of Shellac . The finished amber shows a residue of hydrothermally treated spots of different sizes, which may penetrate the amberâs interior or remain on the polished surface. In comparison, natural beeswax has high toughness, possibly due to its layering structure (figure 14A). Figure A-2. 1, pp. It is usually translucent to opaque, and its opacity is caused by the reflection and scattering of incident light by an abundance of internal tiny bubbles. Sold in liquid, paste, and solid stick forms, waxes are formulated in a host of colors. A: calabash beads (751 g total). (2004) Some possibilities of thin layer chromatographic analysis of the molecular phase of Baltic amber and other natural resins. Matuszewska A., John A. Gold-twisted honey amber: amber with semi-transparent and semi-opaque internal features (figure A-1B). Photos by Yamei Wang. SEM images AâD show the characteristics of natural beeswax. Photos by Yamei Wang. The others were client submissions previously examined at the China University of Geosciences gem testing center in Guangzhou, China. Samples were collected from amber manufacturing facilities. (2006) Systematic Gemology, 2nd ed. There are usually dense, flat, or disk-shaped gas bubbles or gas-liquid inclusions in HT amber. Baltic amber is a specific subset of amber that is found only in northern Europe: it accounts for some 80% of the known amber in the world. What does honeycomb wax look like? These previously examined samples were collected from amber manufacturing facilities. Hydrothermal treatment aims to improve the appearance of amber by artificially creating inclusions, causing the appearance of natural beeswax. A and B: Disk-like bubbles in HT copal resin. Freshly produced ambergris has a marine, fecal odor. 3. Firefly Books Ltd., Ontario, Canada. Evaporation occurs on the surface, while boiling occurs when the saturated vapor pressure is equal to the external pressure. In some cases, yellowish white HT skin is found below the black naturally weathered skin of rough amber (figure 8F). Figure 10. Photos by Yamei Wang. However, the flow lines appear disordered, less well-defined and smooth than the pattern of natural beeswax, which may be attributed to the impact of later gas interventions. There is no price difference between the two. Simply take a bar of wax and rub it on the metal parts, making sure to use a clean cloth after to buff off any excess. A layer of variable thickness of yellowish white or greenish yellow hydrothermally treated skin is generated below the natural, weathered skin of rough amber after this treatment. The client who sent the copal resin beads for examination acknowledged that they went through multiple cycles of hydrothermal treatment, around 20 hours total. Wax. 67, No. These flow lines are often retained in the HT products. 1-2, pp. 142–150, http://dx.doi.org/10.5741/GEMS.50.2.142. Heat treatment is a purification process for squeezing gas inclusions out of the amber to form transparent golden amber, while hydrothermal treatment aims to introduce submicron-/micron-sized bubbles into the amber to create a milky appearance (figure 15). Images of (A) a natural beeswax strand, (B) a roasted old beeswax strand, and (C) a roasted HT beeswax strand. 12, No. $14.95 $ 14. Photos by Yamei Wang. The white HT skin is caused by rapid accumulation of tiny gas bubbles in the highly porous shallow surface of the amber. Infrared spectroscopy shows that it has a higher content of volatile components and succinic acid in the initial resinite than amber from other areas (such as Myanmar, Mexico, China, and the Dominican Republic). Honeycomb wax is a translucent concentrate that has a honey-amber shade. They have opposite outcomes, however (Wang et al., 2010). This goes for seeing if your wax was made/extracted correctly. Overview Information Beeswax is a product made from the honeycomb of the honeybee and other bees. Dr. Li (yanli@cug.edu.cn, corresponding author) is an associate professor at the Gemological Institute and Advanced Manufacturing Centre, China University of Geosciences in Wuhan. Candelilla wax is a bit denser than beeswax, so you will have to adjust your DIY skincare recipes if you are substituting it for beeswax. Journal of Gems and Gemmology, Vol. 665–678, http://dx.doi.org/10.1007/s002690000111, Vîrgolici M., Ponta C., Manea M., Negut D., Cutrubinis M., Moise I., Suvaila R., Teodor E., Sarbu C., Medvedovici A. For example, Colombian copal resin can be transformed into yellow or yellow-green opaque copal after hydrothermal treatment. Search GIA's library catalog of 57,000 books, 1,800 videos, 700 periodicals, and the renowned Cartier Rare Book Repository and Archive. C: spots penetrated the HT skin. Amber has become increasingly popular in the jewelry trade. Three semi-finished amber samples were chosen and polished as much as possible to remove their weathered skin before hydrothermal treatment (figure 4). No such size change was observed within the white HT skin. Photos by Yamei Wang. G&G, Vol. Note that there was no weight change after hydrothermal treatment. Photos by Yamei Wang. A: layering structure. The surface of the freshly HT amber shows a âwater rippleâ structure (figure 8, AâB), and is often locally accompanied by a layer of yellowish white or greenish yellow HT skin with various thicknesses, or a corrugated, crust-like skin containing mostly oval pores (figure 8, CâD). HT amber (figure 16, left) is mostly used for further heat treatment to produce roasted old beeswax (figure 16, right; see definition in box A). 5, No. Three representative specimens, labeled as I, II, and III, were used for the hydrothermal treatment experiment in this study (gemological characteristics of chosen specimens can be found in table 1 and figure 4). SEM images EâH show the characteristics of hydrothermally treated beeswax. 530–542. Submicron- and micron-sized gas bubbles are able to migrate into the amber during this process. There are two types of vaporization: evaporation and boiling. The thoughtful and constructive comments by reviewers and technical editors are gratefully acknowledged. To better illustrate the equilibrium of two-phase wet steam on the amber surface, the hydrothermal treatment process is illustrated in figure 12A. A and B: water ripple structure. B: gas bubbles scattered in the amber matrix. They are crushed, mixed, carefully heated and cooled to form the crystalline amber. E: cracked or brown crust-like HT skin. Gems & Gemology, Fall 2019, Vol. B: filament and flow striation in sample I (field of view 11 mm). Physics and Chemistry of Minerals, Vol. This is a novel method to optimize the appearance of semi-translucent to opaque amber by heating it with controlled temperature and pressure in a furnace in aqueous solution and inert atmosphere. The effect is similar to when a tap water valve is opened all the way and the high water pressure in the pipe causes bubbles to form as air is trapped within the water, making it appear white and opaque. Figure 1. Images of (A) golden amber, (B) gold-twisted honey amber, (C) beeswax, and (D) chicken-fat yellow beeswax. Keep away from children and pets. However, the structure of the roasted HT amber did not change significantly, indicating its durability. Figure 2. Various commercial HT amber products. As explained above, it is feasible for experienced gemologists to definitively identify HT amber pieces. All three developed a layer of khaki-colored, hydrothermally treated skin or white hydrothermally treated spots (figure 5, AâF). Meanwhile, at a certain temperature when the conditions in the chamber are adequate to give the water molecules enough kinetic energy to break away from the surrounding molecules, steam will form. I: color zoning close to the surface of roasted HT amber. H: submicron-/micron-sized bubbles. Figure 15. Much like shatter, wax starts as amber liquid produced by butane extraction and is heated or agitated to produce a soft, opaque material that loses its transparency. âBeeswax,â a term commonly used in the Chinese gem trade, refers to amber that is semi-translucent to opaque with greasy luster. 6, pp. You should not use the information on this web site for diagnosing or treating a health problem or disease, or prescribing any medication or other treatment. The hydrothermal treatment process is similar to heat treatment in practice, as both are completed in a pressure furnace. A series of comprehensive tests are required to identify hydrothermally treated beeswax amber (HT amber). Optical Microscopy and Scanning Electron Microscopy. F: large HT spots. Since the Tertiary period, the geological conditions of the Baltic Sea area have continuously evolved. As it is with the world, humans always find new ways to try to copy nature. Doing so optimizes the appearance of amber by converting it from transparent to opaque to mimic beeswax. E: sample II (golden amber, 2.24 g). 458, No. 5, pp. Numerous researchers (e.g., Brody et al., 2001; Zhang, 2003; Zhang, 2006; Feist et al., 2007; Abduriyim et al., 2009; Ross, 2010; Wang et al., 2010, 2014) have investigated the methods to enhance the quality of amber. The gemological characteristics of natural milky âbeeswaxâ amber are compared with those enhanced by hydrothermal treatment. C and D: oriented and distributed bubbles or residual porosity on HT skin. G: a parallel stress pattern. In addition, the samples have a wide absorption shoulder (Baltic shoulder) in the range of 1261 to 1164 cmâ1, which is attributed to the C-O stretching vibration. These previously examined samples were collected from amber manufacturing factories. Wang et al. The submicron-/micron-sized bubbles (figure 14H) penetrating the HT amber are associated with a certain pressure that has not been disclosed. Amber is a scent so popular that many varieties of the fragrance exist, Golden Amber, Dark Amber, Celestial Amber and so on, each fragrance slightly different than the next. Occasionally bubbles are enclosed in amber to form beeswax, and they tend to become smaller. The VCs mainly include terpenes, unsaturated compounds, and carboxylic acids (Matuszewska and John, 2004). 21, No. Golden Amber is a warm fragrance rich with vanilla, Dark Amber is sweet with a touch of spice and Celestial Amber is has a hint of patchouli-like earthiness. H: disordered flow lines. Acta Chromatographica, No. The gas bubbles are uneven in size and densely distributed, forming a cloud-like effect. Hence, the large amount of artificially introduced nano-scale bubbles (figure 13D, blue circle) in the treated samples will lead to an even more compact structure of white HT skin and a milky appearance. (2014) Experimental studies on the heat treatment of Baltic amber. Sample III was heated after hydroÂthermal treatment. Natural materials were made into less valuable copies and slowly brought into the market. Amber resin is a solid crystalline fragrance made from a combination of many resinoids and oleoresins (plant secretions) such as myrrh, gum frankincense, gum styrax, benzoin, sal tree, labdanum and other aromatic compounds. (2016) used SEM to observe the size and distribution of bubbles per unit area and the area ratio of bubbles in a variety of amber specimens. Photos by Yamei Wang. Identification Beeswax is created by bees, making it 100% natural. Some of the water vapor molecules are recondensed into water droplets left on the surface of HT amber (a permanent residue). Western markets might not enjoy the opaque products as much as the Chinese market. Driven by profit, foreign rough suppliers have converted ordinary and low-quality transparent amber to opaque beeswax via hydroÂthermal treatment to cater to Chinese consumers. Figure 9. Natural beeswax has different shades of … HT beeswax beads are especially prone to breaking or cracking in the process of drilling. Luckily, their “Baltic Amber” candle fits in perfectly with a fall collection. 12, pp. Adjacent gas bubbles may squeeze each other, resulting in deformation and forming stress patterns or lines. HT beeswax is easily burst during processing due to residual stress cracks. Photos by Yan Li. Variations in the appearance of amber samples before and after hydrothermal treatment: samples I (A and B), II (C and D), and III (E and F). D: internal impurities in sample I (field of view 7 mm). Wang Y., Yang M., Yang Y. Keep your baking pans and sheets looking good as new by buffing beeswax onto them before using. Differences most people do not know about beeswax and emulsifying wax. Large Tibetan Tribal Jewelry Ring of Beeswax Amber - Selection. The Mechanism of Hydrothermal Treatment. This is an unusual peak shape for Baltic amber. During the process, an abundance of tiny submicron-/micron-sized bubbles penetrate the amber in an aqueous solution (with some catalyst) through controlling the temperature and pressure and selecting an inert atmosphere environment. A gradual transition was observed (figure 6, CâD) from larger bubbles to smaller bubbles with increasing depth (figure 6, EâF). All of these samples, studied by the authors over many years, were used to show identification features of HT amber. The smaller the gas bubbles, the smoother or more compact the texture is. Last week, I discussed my unusual high school job: pouring beeswax candles at a Greek Orthodox Convent! (2010) Thermal desorption/gas chromatography/mass spectrometry approach for characterization of the volatile fraction from amber specimens: A possibility of tracking geological origins. Gemological Characteristics of Rough Amber Before Hydrothermal Treatment. A white diffusion pattern appears along cracks after treatment of original cracked amber. What about Wicks? 1325–1338, http://dx.doi.org/10.1016/S1386-1425(01)00387-0, Feist M., Lamprecht I., Müller F. (2007) Thermal investigations of amber and copal. Many techniques have been attempted to improve the color of beeswax amber, such as heat treatment. Golden amber: golden transparent amber (figure A-1A). Our amber is sold for the sole purpose of using as incense, we are not responsible for any other uses. When the water pressure is reduced close to atmospheric pressure, the flowing water does not contain so many air bubbles and becomes transparent (figure 12B, top). Hydrothermal treatment is carried out in a pressure autoclave by controlling the temperature and pressure and selecting an inert atmosphere (figure 3), similar to the pressure furnace established for amber heat treatment (Wang et al., 2014). Roasted HT beeswax: hydrothermally treated beeswax that subsequently undergoes heat treatment to enhance its color (figure A-2C). All these features are quite different from the weathered skin or cracks on untreated amber. In general, 30à or higher magnification is required to see bubbles in natural beeswax, while 10à magnification is sufficient for HT amber. Volatilization refers to the process in which volatile components (VCs) contained in the original resinite continuously escape during the geological process. 18, No. Beeswax: a common term in the Chinese gem trade, referring to semi-translucent to opaque amber that has an opalescent, milky appearance with greasy luster (figures A-1C and A-2A). Figure 14. The size range of gas bubbles in HT amber is substantially greater than that in untreated beeswax. Dense, flat, or disk-shaped gas bubbles or gas-liquid inclusions are commonly found in HT amber (figure 9, CâF). From shop StoneHandiCraftDe. Visiting the factory, author WYM also noticed features that developed on HT rough amber. Some waxes are softer, some are harder, but even the hardest waxes are softer than lacquers and varnishes. Thermochimica Acta, Vol. This disk can penetrate the amber and remain on the surface after polishing (figure 7, CâD). As far as I know, Amber Shellac has been and always will be the classic retro finish for knotty pine.Our grandpas and dads were putting this orange-honey-gold finish on their unfinished knotty pine back in the 1950 and 1960s — and the product is still available today as Bulls Eye Shellac, by Zinsser, which is a Rust-Oleum Company. A white diffusion pattern appears along the cracks after hydrothermal treatment of originally cracked amber (figure 9J). Gas bubbles in natural white beeswax can only be observed under SEM of 5000â10,000à magnification. 2018YFF0215403 from the National Key R&D Program of China. 55, No. Ross A. Wang Y., Wang Q.Y, Nie S. (2016) Gas bubble characteristic of translucent to opaque amber and its relationship to quality assessment. Dr. Chen is an associate professor at the Gemological Institute, China University of Geosciences in Wuhan. HT amber retains the natural flow lines of gold-twisted honey amber. Once softened, the amount of gas bubbles penetrating the amber during hydrothermal treatment is related to pressure. HT: hydrothermally treated, as in HT amber, beeswax, or copal resin. The color of the golden amber (samples I and II) became darker, while the gold-twisted honey amber (sample III) became white. Microscopic Characteristics of Hydrothermally Treated Copal Resin. Photos by Yamei Wang. These samples were from a clientâs collection. G&G, Vol. Characteristics of Rough Amber Material After Hydrothermal Treatment. E: round dot-like HT spots. If ingestion occurs, seek medical attention. Please note, amber will melt and liquefy above room temperature. 14, pp. F: yellowish white HT skin below the weathered skin of rough amber material. An important value factor of beeswax is âwaxiness,â a term that describes whether the materials look and feel compact and uniform. Larger bubbles generate more surface area to diffuse light, but they also make the texture of beeswax rough. The project was partially supported by the Fundamental Research Funds for the Central Universities, China University of Geosciences (Wuhan) (No. Amber is a composite of many resins and herbs, created in India by one of several master formulators. 162–170, http://dx.doi.org/10.1016/j.tca.2007.01.029, Guiliano M., Asia L., Onoratini G., Mille G. (2007) Applications of diamond crystal ATR FTIR spectroscopy to the characterization of ambers. Due to the saying âMillennium amber, million years beeswaxâ in the Chinese gem market, many Chinese consumers mistakenly believe that beeswax takes much longer to form than amber. Journal of Gemmology, Vol. B: light yellow and yellow beeswax drop-shaped pendants. 5, pp. The gemological characteristics of these rough amber specimens (samples I, II, and III) before hydrothermal treatment are listed in table 1. Amber was discovered during the early 18th century when a group of scientists found a way to synthesize it. Amber when tested does not melt as quickly as the copal and emits sooty fumes This lowers the potency because of the plant matter. The appearance of HT amber is mostly uniform and waxy. HT copal resin instead shows more concentric rings and a straight, irregular, and banded or striped texture (figure 10, AâD). These are typical examples of commercial HT amber and HT copal resin to mimic natural beeswax in the trade. D: spots on the polished surface. It sometimes displays white HT spots as well as a compact structure.
