help with adding color to 4c cullet
I know it's opening a big can of worms so if anyone can point me in the right direction I am willing to do the research and I would appreciate the help. I am a new student and I am just trying to get something different than black and cobalt blue. I have seen a red attempted but it came out green. I saw a sample that was melted a couple years ago and it was real livery and brown but no surprise there. I have seen a bucket marked green but we only have 2 colors that we melt. Our current method is to mix the colorants and cullet in a 5 gallon bucket then charge into a small 4 pot gas fired furnace. I don't think there is a squeeze or anything like that but I guess we could if we had to. I asked a few advanced students why we only had a few colors and they answered something like if there were other colors the guy that built the furnace would have known about it. I mean I know we can't do any expensive melts but there has to be something else and I would like to get some numbers together so I know how much not to exceed when adding stuff so it will still fit the base and all that. I know it's a big question and it's been covered before so I would be happy with a nudge in the right direction. I am willing to experiment but I know there are more than 2 colors we can melt. It'd be fun trying anyway. They might not be red, yellow, or orange but I'd be happy with puke green and purple. I own Weyl's "colored glasses" but it's a little above my head still. I can feel the eyes rolling now but I won't know where to start my research if I don't ask. sorry for the dumb question.
