This is probably pretty obvious to almost everyone, but just in case ...

Don't try to warm PR in any way that would allow it to catch fire. No open flames or anything that might spark.

Styrene has a flashpoint of 90F. Don't overwarm your resin.

Chestnuts roasting on an open fire won't make anyone's Christmas merry if the fire is your house/shop.

The last time I made a small 5 oz batch heating it in a glass container and placed that in a pan of water & I heated it on a hot plate, then mixed in Mekp and pigment and poured in molds. I didn't think to heat the molds. I put it in my basement which is 60-65 degrees. I think the low temp is my issue. Gotta find a way to store in warmer area. My wife hates the smell so doing in the house is not an option. Anyone ever try drying with blow dryer?

I use the same coffee cup/candle warmer that I use to heat the PR I've used to heat the molds and the blanks. Just make sure water doesn't get into it.

I use a large soup can and hot tap water to start. The warmer only gets the water up to around 200 F even with some insulation wraped around it.

Thanks everyone! I tried heating again on a hot plate. Then I mixed in my color and then added the MEKP and that did the trick. In fact, it worked so well I had to pitch 2 batches because I wasn't ready before it gelled up. The last batch worked great. I was actually able to heat and pour in in to my molds. I put the molds in a plastic container with a lid to trap the heat and it set up nice in my cold garage. Thanks again!!!
