A Chinese Pure Copper Medicine Grinder from the Mid-to-Late 20th Century This pure copper grinding tool, shaped like a boat, transcends the realm of ordinary tools, making it a precious artifact that blends sculptural art, precision mechanics, and traditional cultural symbolism. Traditional Chinese medicine grinders have a long history, traditionally associated with the renowned physician Hua Tuo of the Three Kingdoms period. They were essential tools for ancient physicians in preparing medicines. Copper grinders, due to their durability and resistance to chemical reactions with medicinal materials, were the preferred choice for pharmacies throughout history. This boat-shaped grinder is a prime example; its unique shape and warm patina add a distinctive oriental charm to any space.
