Colors?

I have very recently started making molds and pouring my own baits.
I have noticed that the plastic that started out chartreuse is now orange. It gets darker with each heat. Is this normal? Am I getting it too hot? Any words of wisdom will be appreciated. Thanks.

your plastic is over heating, get you some stabilizer from lurecraft. That stuff will save lots of plastic. it allows the plastic to be cooked over and over along with hotter with out discoloring. It doesnt take much. Plastic comes with it but it gets cooked out of the plastic over time so you need to put more in

I will do that. I knew someone would know the answer to my question. The orange is a usable color also. Thanks a lot.
