LiamPyro Posted August 18, 2015 Posted August 18, 2015 After finishing my 5-gallon bucket star roller, I spent the next couple hours rolling my first batch of stars, which were Tiger Tail + 10% Ti rolled onto millet with 75/25 water/alcohol. I know charcoal comps can be hard to roll, but I have limited amounts of color composition chemicals so I figured I'd give it a go. Anyways, the cores (about 1.25 spoonfuls) started easily and grew nicely to about 1/8", at which point I took out about 2/3 of them and left the other third to roll. This was because I only had 100g of star composition and wanted to grow them to 1/4". Some time after, when the stars had grown a little, they began to raspberry. I immediately sprayed them with solvent until they were nice and wet, then let them roll for about 5 mins. This reduced the problem, but the raspberries were back as soon as I added powder and wetted again. I tried increasing the percentage of alcohol, which had essentially no effect. I also had problems with stars sticking together from too much moisture, which further screwed them up. The resulting 1/4" (roughly) stars were a complete raspberries, but had surprisingly close size even though I didn't screen them whatsoever. What did I do wrong? Is there any way to avoid this in the future? Should I change the RPM of the roller? Should I change the angle? Would pics of the setup help? Should I try a color composition such as Buell Red? Thanks for any help!Here's a picture of the finished stars, note that some were sort of broken-off chunks of other stars, which is why a few are much smaller.

LiamPyro Posted August 18, 2015 Author Posted August 18, 2015 Alright. Does this help prevent raspberries?
