I like to experiment with new materials, colors and such. I am using casting resin for a while now making my own paper micarta and various colored sheets to be used as scales for slingshots of course. At first i made a square casting form to make sheets and cut out the slingshot designs as usual boardcut. But in the longrun that was quite expensive because of the cut offs that cannot be used further and not all colors are nice enough to use them on a slingshot. With my blossom design my wish for more colors and experiments with casting resin grew stronger and i decided to make a silicone mold to cast a slingshot scale without the need of cutting it out of a full sheet. On the first picture you see the silicone mold made from my master-template. It only takes ~20ml instead of over 300 for a full sheet. So far so good. Color pigments usually mix perfectly with the resin forming a homogenous suspension resulting in a completely colored cast. But for some reason, nightglow pigments don´t behave like that. On my fist try with nightglow pigments i only got a thin layer of those on the bottom of the sheet. Next two tries i used different thixotropic powders to make the solution thicker ( one was recommended by the resin manufacturer for my problem ) but it still doesn´t work. As you can see on the next pictures, the nightglow pigments still settle on the bottom of the casting mold and do not stay in solution. My goal is to imitate the nightglowing kirinite sheets that i recently bought. My last try with a 15 ml amount of resin i used a half tablespoon of nightglow powder and a teaspoon of the thixotropic powder and stirred for 20 minutes... it takes that long to make the pigments dissolve properly. My guess is, these pigments are heavier than normal color pigments. But there must be some way to keep them floating. If someone have any idea how to solve this, i would be happy. Thanks.
