Blue Glitter turning plastic blue
« on: 06/08/16 13:29 UTC »
Using .35 Blue glitter (can't remember if it is Do it or some other brand), but I am noticing about halfway through reheating 6oz batch over and over, my white/pearl baits are turning a bluish shade.  Are there glitters avail that won't transfer the color to plastisol?   Or special tricks?

make sure it is polyester glitter and even then you will get that with reheats.  I suspect the heat is too much.  On remelts it does not take the same heat level of new plastic.

Some remelts are much better used in darker colors such as Black.

Some colors will bleed regardless of where they come from and re-heating/re-melting seems to be the trigger for the problem. Canada Blue, Purples can be bad. I try to use any batch of clearer or colorless plastic in one session with only one re-heat. If I have a lot of baits to make using clear plastic containing either blue or purple I make smaller batches that get used quickly and re-heat one time. Since I use a ton of purple plastic, once a clear using blue or purple glitter has been used as far as it can go I just add purple colorant to it and continue using it because the bleeding won't matter. Also, add the glitter AFTER the plastic has been cooked to the 350 degree conversion temperature and you'll be a lot happier. I've tried a million different purple and blue glitters and they all bleed even though they are sold as a non-bleeding glitter.

Are you doing multiple reheats in the micro? If so, try getting a hot plate and doing your initial heat in your micro then setting your Pyrex on the hot plate or some use a griddle. Shoot, purge your injector right into the Pyrex and stick your injector right in the Pyrex with the hot plastic. Demold after 2 minutes and you should be able to keep injecting without micro reheating. Most hot plates and griddles have a thermostat and after some use, you'll get a feel for where you need to keep it and have your plastic around 300 or so.

Great suggestions.  I will try smaller batches first until I can try the hot plate method.  I add glitter after the initial melt, but then reheat back to a inject-able state.  After 3-4 reheat times is when I start to see the color change.  I am sure the fish really don't care about the blueish tint.  :)

You can, in fact, end up with some super nice bait colors because of the bleeding. The gun metal-blue flake in clear plastic I make for panfish baits I now make adding the glitter to the raw plastic and as soon as it hits the 350 mark I let it cool enough to have to re-heat to inject and the clear plastic will have taken on a nice blue/smoke color Its really a nice color and very, very productive.

Here's a picture of the gun metal-blue glitter clear plastic. You can see some of the uv coming out in the lower section of the bait's body, but there is no colorant or hi lite used in this bait. Its all bleed from the blue and gun metal glitter. And honestly, I have taken more fish this spring on this bait color in three or four different bait styles and shapes than I have all of other colors I make combined. I've tried to replicate this color without the glitter and I can't even come close. The two glitters are both .015 size and I make a pre-mix blend of the two glitters so that when I add it to the clear each batch will be the same.

Sometimes the bleeding isn't such a bad thing.

reheats are a bugger sometimes. short burst stir frequently.. like AP said maybe try a hot plate and maybe even get a cheap fry pan or some other flat pan . Then later on when doin laminates u can put both pyrex cups in it and keep them the same temp
Some glitters bleed especially purple
good luck and be safe!!
