more SP Colors and some for cullet too!
« on: February 16, 2019, 10:52:23 AM »
Jordan Kube offered this list of recipes given to him by a colleague.

Interesting discussion follows with important insights by Pete in terms of expansion and compatibility; also questions if these were for a 50 lb bag rather than 100 lbs. If you want to use these...perhaps look over some of the other Batch recipes posted here and see how much colorant was used for similar colors.

Jordan:
So I was reading an old thread about melting black and I realized I had some formulas lying around. These were given to me by a guy I worked with who said they were from a class at Pilchuck. I'm
going to copy these word for word. No I've never melted them, don't know anyone who has, can't tell you a thing about them. There aren't any temperatures given. I'm sure Pete will have some advice. Discuss below, Happy Birthday.
