Mason stains to make colored slip

Recommended Posts

Marge    0

I'm playing with stains to add to my slip for slip trailing on my greenware. I've slaked my clay and have a bucket of slip that I have sieved and want to add Mason stains. How do I figure out the stain to slip ratio? Is it just a visual thing? Does the final color (after bisqued) look similar to the original trailed color? Thanks in advance for any help!!

I add 1/4 cup of Mason stain to 2 cups of slip (I use porcelain clay to make my slip). Some stains are stronger than others, so you might have to experiment. After bisque, take a sponge and dampen the colored slip; that will be a better indication of final color.

I use about 25 % or less of mason stain in my porcelain slip depending on what colors I want. since you are using stoneware, you will need to test. Some stains responds well with some chemicals and others do not.b est to use the reference code as a guide for whether they can be used as engobe a stains, with calcium, with or not with zinc, what are their maximum temperatures, etc. You can google Mason stains and find reference codes.
