Chenet is a fancy French word for andiron.  Andirons were used in fireplaces to support logs as they burn. They typically come in pairs. Andirons are elevated, allowing for better air circulation under the firewood. This resulted in more efficient burning and less smoke.

 

Bronze d'oré, also known as ormolu or gilt bronze, was a decorative finish used on luxury furnishings in the 18th and 19th centuries. An application of finely ground high carat gold and mercury amalgam was placed on objects of bronze. When subjected to extremely high heat, the mercury evaporated, leaving behind a lustrous coating of gold.
