If Your just starting out with mixing your own glazes you need some items other than the raw materials. A few of the items are:
sieves, large and test size
buckets with lids
mixer, I use a kitchen hand blender, you can use a drill (although I got plastic chunks in my glazes from the drill on the bottom of the bucket.)
brushes, spatulas, trays, etc..
fine particle mask
place to mix and to store materials
I'm sure there are more I can't think of at the moment.
