So this past weekend I was pouring up some plastics, and I wanted to make some green ones. I slowly heated my Alumisol on low in the microwave to just above 350 degrees. I stirred in a drop of green Alumisol dye, and it turned BLUE! Not green! I though this was weird, and thought that maybe I had overheated the Alumisol and that caused it. So I started again with a new batch. I slowly heated and measured the temp with an infrared laser thermometer- 356 degrees. I mixed in the green dye, and BAM! BLUE AGAIN! Has anyone else noticed this? Also, I ordered some Florescent Orange dye and upon arrival it was more like paste than liquid in the bottle. I understand there will be some separation if the dye sits around, but what I've done to remedy this is pop off the "dropper cap" from the bottle, and take a small slotted screwdriver to stir. This is to no avail with the florescent orange. There's no separation. It's just thick like paste. I know it's nothing I've done, because I store it next to my other colors, and they are just fine (with the exception of the green and it's erroneous color of course). However, the main reason I'm writing this is regarding the green dye. It looks green in the bottle, and it looks green on the small metal applicator I use to transfer it from the bottle to the hot Alumisol. But as soon as it touches the Alumisol and I stir it in, it instantly goes blue. Fortunately I was able to make my own green with yellow and blue dye, but the way I look at it, I shouldn't have to concoct my own color of green if I ordered green dye. Just frustrated.
