Note: This version can be used when it's impractical to measure the weight of the glaze in the bucket. Here, after weighing a syringeful of glaze, you add a certain amount of water to the glaze (the amount is up to you; hopefully it won't decrease the specific gravity more than desired). Stir the glaze well, and then weigh a syringeful of glaze again. Enter the desired specific gravity, and the program will calculate how much more water you need to add to reach that specific gravity.
