The Limitless Possibilities of Mason Stains
At the end of the day, using mason stains requires a bit of testing, no matter what application you are pursuing (some less than others). Each different stain has its own properties, and some colors are more powerful than others. You may only need 2% (by dry weight) of Sage Gray, but 15% of Titanium Yellow to achieve the same level of saturation for each color. And those are just slip colorant percentages for cone 5/6. If you want to make a Titanium Yellow glaze, your percentages will be different. If you want to make a low-fire slip, again, your percentages will be different. With so many variables in the mix, it is important to take the time to test!
