Marge Posted April 11, 2013 Report Share Posted April 11, 2013 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!! Margie Link to comment Share on other sites More sharing options...
bciskepottery Posted April 12, 2013 Report Share Posted April 12, 2013 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.

Marcia Selsor Posted April 12, 2013 Report Share Posted April 12, 2013 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.
