This was givin to me and it doesn't have any info on it. It is a hard plastic . I don't know if it can be put into oven ? Maybe some hard plastics can I don't know.
If it is a microwave mold does anyone ever use these kind and if so what recipes do you use.
thanks for any help

How big is it? It could be a chocolate mould, or a jello/jelly mould... I doubt it can go in the oven though. Microwave maybe.

It is 8 " long and 43/4 " wide

It looks to me to be a jello or chocolate mold.
There is a slight possibility it's a MW cake pan but it looks heavier/ticker those.
If it's a jello mold I bet it could be used in the MW.

Thanks
