The natural and lacquer properties of wooden tableware

If we do not ask the store in detail, we often find that most of the wooden bowls we buy in supermarkets or online have been painted. Raw lacquer is corrosion-resistant and wear-resistant. This lacquer method, which was the only one used in ancient China, comes from the lacquer tree. Its milky white colloidal liquid turns brown and hardens into lacquer after contact with air. Raw lacquer is corrosion-resistant and wear-resistant, and has good acid resistance, solvent resistance, heat resistance, and water-proof and insulating properties. Therefore, it is often used in military industry, industrial equipment, agricultural machinery, infrastructure, handicrafts, and civilian furniture. However, raw lacquer may cause allergic reactions, so be careful when using it. The toxicity of chemical lacquer is more well-known and is not suitable for holding food.
