Glaze Mixing Mayhem

My day, sigh.
I've been working on simplifying my process of glazing so I've been slowing retiring old glazes and consolidating glazes, over 100 glazes is too many!  My frugality wont let me just chuck them out, so I've been mixing the left over into big buckets and adding a little colored oxides, tin oxide and other glaze ingredients, then testing to see if they are any good. So far I've consolidated about 25 glazes into 4 buckets and have some great colors-- never to be reproduced.
