What is the difference between Silver Porcelain by Tiancheng products and mercury-amalgam-gilded (liuyin) or electroplated silver products?
- Mercury Amalgam Gilding (鎏金鎏银工艺): This process uses a mixture of silver powder and mercury, posing a risk of mercury poisoning, and is therefore strictly prohibited by law for use with food-contact utensils.
- Electroplating (镀金、镀银工艺): This process uses electrolysis to attach a metallic film to the surface, requiring the use of highly toxic substances like potassium gold cyanide and potassium silver cyanide, and thus should not come into contact with food.
- Silver Porcelain by Tiancheng Products: Lead-free, cadmium-free, and harmful-element-free fine gold and fine silver raw materials are sintered onto the ceramic surface at high temperatures through eighteen processes, resulting in the metallic luster of fine gold and fine silver on the surface.
