Its burning. How are you getting the temperature....using a digital thermometer I hope? Are you using a microwave?...if so you need to break up the cooking time and stir often. What are you cooking the plastic in...a pyrex cup or something different.
cooking in glass pyrex cup. I must be heating it to quick on the second time. for a cup I start with 2 min then stir heat again 2min then stir then 1 min then stir taking temp after second heating what am I doing wrong CTom. Thanks Dave.
Do it sells heat stabilizer this stuff is you friend. Get a big bottle it's a must on light colors .

lowel, I have it. do you use a lot or a few drops at a time? Dave
I add a few drops before every reheat. If it's still turning you're just heating to much or to fast. Get a good termometer. Like tom said heat 30sec at a time.

If you are going to do light colors and will have to re-heat them a couple times, forget using stabilizer in terms of drops....1/2 teaspoon to 4 ounces is better. Stabilizer cooks off with repeated heatings so it has to be added again after a couple of reheats.
The Essential plastic is a very heat tolerant plastic but stabilizer will give you the extra cushion that goes beyond the plastic and helps keep the colorants from turning. Colorants as a rule don't have much if any stabilizer in them and are as prone to burning as a plastic is so when you mix the raw components add plenty of the stabilizer and the entire batch is buffered against a heat surge. If I can see that I will need to reheat a lighter color to continue working I'll add a shot of stabilizer and stir it in while the plastic is still fairly fluid, then reheat when its needed. Its a process that has to be experienced and learned because everyone does things in their own fashion....there really is no recipe for learning this.
White and chartreuse are about the worst colors to deal with. White has a ton of pigment and all that pigment is largely unprotected from over-heating unless you add stabilizer , and enough of it, to help protect the pigments themselves. In white, the pigments are what burns first. Chartreuse is pigment heavy and the same applies for it.
White is a tough color regardless of what you do.
No doubt, BJ. White is just a hard color and never does making it get easy or without headaches.
Thanks Tom and BJ, I think I will just mix white in small batches from now on and slowly reheat with alot of stabilizer If I am reheating white leftovers, say cut them into small pieces and at what time do I add the stabilizer? when its fluid or at the very start. Thanks again guys. Dave
If you don't mind pearl baits, white pearl powder keeps a uniform color and hides a lot of yellowing issues.
I'd add it as soon as the heating yields some liquid plastic to stir it into. Remelts don't melt uniformly so the liquid plastic you see before everything has melted will get the hottest and needs the protection when it first shows up.
depending on which plastics that you are using there is a big difference between the different manufacturers out there some of the plastics will darken very easily are turn yellow very quickly I know there is a lot of pro and con here.Quote:

A nice bright white. All I do is add a little stabilizer to the plastic before I cook it and it's all good. I don't mess with small batches, all 2gal or more.

Anglers choice, 2 gal batch i couldnt even think of a batch that big.I still use 2 cup pyrex cups. Dave
Thats 2 gallons per side, when he runs laminates its a 4 gallon batch. Lol
Hmm I've never had problems with white and actually think it is one of the easiest as far as bubbles are concerned. As suggested back off your heat times and add stabilizer every so often.
well guys I got it down now. I just slowed down the heating and it worked for both chartruce and white. Dave
