Plastic products cannot be put into the oven, and ordinary glass, ceramics, paints and volatile products are not suitable for oven heating.
Extended data:
The container put into the oven must be temperature-resistant, usually metal, and the silicone rubber mold is no problem. Plastic is definitely not good. Ordinary ceramic plates are not recommended to be put into the oven, and local heating may crack.
Plastic has a low melting point and will melt, and some chemicals such as plastic additives will be released at high temperature. If the colored glaze on ceramics is inferior, putting such ceramics in the oven will also cause toxic overflow. Ordinary glass and tempered glass containers are easy to burst at high temperature, so they can't be put into the oven, otherwise there will be a danger of self-explosion.
