Can I bake clay in my oven? Is it going to make my oven treif?

 

Questions:

Is there an issue with baking clay (like modeling or fimo) in my oven? The instructions are to bake it so it gets hard and keeps its shape. Does it present kashrus issues or not?

Is there a kashrus problem with melting crayons in the oven or microwave? If so is there a way to do it that won’t make the oven treif?

There is a craft where you draw on plastic and put it in the oven to shrink. Is it a kashrus issue?

 

Answer:

It’s not a problem if it is inedible or if it is double wrapped.
