Gemstones in Metal Clay
Gemstones in Metal Clay Many natural gemstones can be set into metal clay and fired in place. Other gemstones will not survive the heat of a kiln and should be set after firing. These charts show the results of kiln and torch tests that have been performed on both natural and synthetic gemstones, adapted with permission from the original testing by Kevin Whitmore of Rio Grande. This information is for reference and should be used as a guide. There is always some risk of losing a natural gemstone even if others of it’s kind have survived in the past. Gemstones may have internal flaws that can be liquid or gaseous filled, or contain crystals of other materials that can cause the gemstone to fail where it usually does not. This guide aims to help metal clay artists sort out gemstones that are known to survive under fire from those that are not. Gemstones are minerals that are classified into groups based upon the constancy of their major properties. Each mineral family has one or more varieties contained within the group. When we sort the tested gemstones according to their mineral group, it becomes clear that an easy way to gauge the survivability of a gemstone is to look at the results of other varieties within that same group. Aquamarine and emerald, for example, are both varieties of the beryl group of minerals. The result of tests done on aquamarine and emerald indicate that minerals in the beryl group will not survive kiln heating. There are exceptions, as there always are in the natural world, but in general this method can be reliable for many varieties. -
GOLD in MONGOLIA - Overview of Value Chain from Mine to Fine Gold Jewelry
Bundesanstalt fur Geowissenschaften BGR und Rohstoffe GOLD IN MONGOLIA Overview of value chain from mine to fine gold jewelry Technical Report prepared by Bundesanstalt fur Geowissenschaften und Rohstoffe (BGR) and Mineral Resources Agency of Mongolia (MRAM) Funded by Bundesministerium fur wirtschaftliche Zusammenarbeit und Entwicklung (Federal Ministry for Economic Cooperation and Development) A A contribution to the Integrated Mineral Resources Initiative (IMRI) Bundesministerium fiir wirtschaftliche Zusammenarbeit und Entwicklung GOLD IN MONGOLIA - Overview of value chain from mine to fine gold jewelry The report aims to provide information and data for the production stages of the value-added chain from the mining of gold to the fabrication and retailing of gold jewelry. It addresses open questions and describes opportunities and shortcomings in the value chain from raw gold to jewelry products, and therefore, it is a useful information source for decision makers and entrepreneurs in the gold jewelry sector. BMZ (Bundesministerium fur wirtschaftliche Zusammenarbeit und Entwicklung/Federal Ministry for Economic Cooperation and Development) strives to underpin democratization and poverty reduction by creating a sound mineral resources based economic development of Mongolia. An extension of the value chain of gold to integrate local jewelry handicraft workshops and the retailing of jewelry is in line with this concept because it contributes to the diversification of the Mongolian small-and-medium enterprises landscape. Collection and processing of data in Mongolia started in April 2012. Official statistics, data present in the Mineral Resources Authority of Mongolia, interviews with numerous experts in this field and the study of published company reports were the main sources of data. -
