Agate and Bronze Casket, French 19th Century

• Agate - Agate is a type of semi-precious gemstone that is made up of silica dioxide, a mineral that is also found in quartz. It is known for its distinctive banded patterns, which are created as layers of silica are deposited in different colours including red, orange, yellow, green, blue, and purple. It is often used in jewellery, decorative objects, and other decorative items, and it is prized for its beauty and durability. Agate is found in many parts of the world, including Brazil, India, and the United States.
• Bronze - An alloy of copper and tin, traditionally in the proportions of about 9 parts of copper to 1 part of tin.
  
  The discovery of bronze in Western Asia in the 4th century enabled people to create metal objects which were superior to those previoulsy possible because of its strength and hardness, and it has been used throughout the world for weapons, coins, tools, statuary and other decorative items.
  
  It is very fluid in a molten state, and its hardness, strength when set, and non-corrosive properties makes it most suitable for casting sculpture.
• Calamander / Coromandel - Calamander wood, also known as coromandel wood or coromandel ebony, is a type of hardwood that comes from the Calamander tree (Diospyros quaesita), which is native to Sri Lanka, India, and Southeast Asia. The wood is known for its dark brown or black colour and its distinctive figuring, which can resemble a snakeskin pattern.
  
  The wood is highly prized for its beauty and durability. It is often used in fine furniture making, particularly in the production of inlaid and marquetry work, as well as in the making of boxes, cabinets, and other decorative items. It is also used in the manufacture of flooring, paneling and other architectural applications.
  
  Calamander wood is a very hard and heavy wood, it has a density of around 1.04 g/cm3. Its density and high natural oil content make it resistant to decay and insects, which is why it is a popular choice for outdoor furniture, flooring and other decorative items.
  
  The wood is also used for turning and carving, but is difficult to work due to its high density and interlocking grain. However, it takes a high natural polish and has a beautiful lustre, which is why it is so sought after.
  
  Due to the high demand and over-exploitation of the natural resources, the calamander tree is now a protected species, and the harvesting and export of the wood is heavily regulated.
