Had problems with today's pour

[Blackhawk19]

I'm still new at this and today I tried doing a 2 color with a lami plate. I was doing clear with glitter and chartreuse (X2) the first pour went great but on the second pour the clear yellowed a little and the chartreuse turned almost orange. I did have color stabilizer in the chartreuse (4 drops). I am open for any ideas and it may be that I just overheated them on the second pour. At this rate I'll go broke buying plastic

What was the temperature of the plastic on your second pour?

[Blackhawk19]

Over 300°, almost 326°

sounds like over heating,

[Blackhawk19]

What should you rewarm to after the first heating?

[Brent]

What molds are you shooting? are they larger baits or smaller? You didn't mention how much plastic you have either? 4oz? 6oz? or more?
I think before we talk temps, we need to get the chemical make up correct. stabilizer/plastic
Keep in mind that adding more stabilizer will affect over all color because you have added another item to the recipe

I use alot of stabelizer when i make light colors and add it everytime i reheat it that helps me alot i usually only do 1 cup at a time when i make baits

Just a couple more thoughts,
what size microwave are you using? and how long are you putting it in on the reheat? are you stirring in between or during that time?

Microwaves can vary and will often make "Hotspots" I have reheated small amounts of plastic many times but have had to use 15 seconds at a time and plenty of stabilizer to keep it from scorching

I was pouring a 2.25" crappie carrot and a 1.75" bait using 4oz of plastic for each color. I put no stabilizer in the clear.

Both of those colors are temperamental, especially on reheats.  Personally, I'd go with with 7-10 drops of stabilizer in 4 ounces and maybe add a tad more with each reheat.  I'd also suggest heating at small intervals...15 seconds or so.  The reheat temp is going to depend on your molds.  Some pour well at 310 while others require 330 or thereabouts.

800 watt micro and what do you mean by plenty of stabilizer(how many drops?) and do you add every reheat.

I Agee with Denny. Heat to 350 on the first run, then 320 or so for the second (whatever works for the mold)I'm really starting to think that high wattage microwaves are causing issues at full power. I have a cheapo WalMart microwave a seldom have overheating issue IF ...and I think it's a big IF... I keep my reheat times to 20 seconds and stir between.

How much plastic are you using? 4oz and an 800 watt micro I would start with 12-15. On the reheat maybe 15-20 seconds at a time. For the lighter colors I would add 5 drops for each reheat, this might be over kill, but so is yellow plastic

SORRY for some reason I never saw you mention size and plastics

I have a $49 Wally World special also.

1-2 drops stabilizer per oz plastic seems to work well for me.  Reheating between shots I do 10-20 secs.  My microwave is ancient, probably low watts.  If I keep low reheat intervals and stir well, I usually don't have problems with burning.
