You will need to go to a ceramic supply store as they supply chemicals specifically for potters. A 5 gallon pail of glaze is about 10,000 grams of material plus water. I would suggest that you mix a smaller batch first, say a plastic ice-cream pail size. This would be 1,000 grams. Make some clay test tiles as well. You will also need to sieve your glaze. I use a 100 mesh sieve-this means 100 screen holes to the square inch. There are lots of videos on youtube about how to follow a glaze recipe and mix a batch of glaze. I like Simon Leach's "How to" videos for this.It's pretty difficult to describe how to do this in an Email. Kind of like telling a person how to land a plane over the phone. [analogy borrowed from Mark C.].
Welcome to the wonderful world of ceramics, and good luck.
