Thread: Reheating plastic

For me it depends on the color i am pouring. I find that white and chartreuse are the worse in losing their color after a few re-heats. Once the lose to much color they became black,brown are dark blue plastic.

can you bring back the color by add more colorant.

You can add more but it will never bring it back to the original color best bet is throw it in the scrap bucket and start over you can always circle back to it and have a scrap bucket throw down i have made some awesome laminates out of the scrap bucket there is just one problem you will never hit it again.

After about two or three times of reheating, white and chartreuse, I usually throw them out all the other colors we reheat but your course like bug man said they will never come back to the bright color that they were. when you add more plastic to something you were reheating, what happens is that you will thin out the color that you were wanting so you have to add more coloring and sometimes this could be a pain in the butt to try to get it back to where you recently wanted it.

Yep I always line my molds up when pouring white, pearl or chartreuse because I want to do as few remelts as possible. You can add a little white to perk up chartreuse but white/pearl is done after remelting. They go straight to scrap heap until I need a dark color. I never ever make those colors in big batches.

that was a lesson learned here, I made a pretty good bit cause I use a lot of chartreuse. Reheated twice and it is already changed from the first pour, I only have one mold, so I only need to mix up small batches in chartreuse and white.

What are you using for cups?i used to use the high temp silicone cups but came to realize glass is a whole lot better for holding your colors after a few reheats.
