The continuous working temperature should be lower than 200 C.2. The limit temperature of the silicone heating plate is about 200 degrees. When the temperature exceeds this standard, the heating plate is easily burned out. The silicone heating plate can't be put into the water. It doesn't matter if the surface is stained with water during use.3. The silicone pad heats up quickly, please take anti-scalding measures!
