I'm using Alumilite resin dye. I understand that some people use a toothpick to extract dye from the bottle, since it is too thick to squeeze out. I would like to thin the dye so it flows better. Can I add alcohol to thin this dye? Is there another reducer recommended for dye? Or is heat the only way to reduce viscosity?
I'm not sure about adding alcohol to alumilite dye, but I had some pigment custom mixed at a local paint shop, and for his first try, he used an alcohol-based pigment, and it definitely did NOT work - it caused the resin to bubble and foam. The next try, using a different kind (I don't recall what) worked perfectly. It's pretty thick, but I only need a tiny amount to color my castings, and it stirs and mixes right in. What I do to measure it is use a small wooden stirring stick, like you'd use for coffee, and I make a mark on the stick, say, 7mm from the tip, then dip it into the pigment up to that mark. It took a bit of experimenting to get the amount correct, but I've found it's not super-critical, 6mm-8mm worth works about the same.
