I poured with a two-burner hot plate for a long time....yes, you have to be careful not to burn the plastic but pouring with a hot plate is doable. I recently thought that it might be good to make a little stand of some sort so your pan is an inch or so off the burner. Don't know if this would work or not but sounds like it might reduce the scorching. You'll have to regulate your plastic temp by removing the pan (s) from the burners and putting them back on and doing lots of stirring. You can't leave a pan on the burner without stirring for very long. One thing I know for sure is pans are much easier to pour from than Pyrex, especially with open molds where you need a thing stream of plastic. If I had to pour with Pyrex I think I'd give up. Good Luck.
