Please note that we try to help you solve problems with glazes that are in our book "Mastering Cone 6 Glazes" without charge. Please just email us for help with those glazes. The service described in this section is for other glazes with which you are having problems.
Glazes. Some times a glaze will change and not for the better. This can happen for a any of several reasons but the most common is a change in the materials used in the glaze.
Ron Roy offers a guaranteed reformulation service to address such changes. There is a one time fee of $40 - You will do the mixing and firing - most times it takes only one change - sometime two or three.
Clays. Most clay bodies don't come with a recipe; however, there are still ways to help correct some problems. We will be happy to try and help - the cost is $40 per hour.
The information we need.
1. A clear and complete description of the problem.
2. A recipe with the specific brand names of the materials used.
3. A short description of your firing cycle including overall time and cone bend.
4. A decription of your kiln and the controls you use with it.
Sample problems -
#1 Glaze crazes two or three days after firing. Solution - Lower expansion rate - this is an easy problem to solve.
#2 Glaze finely crazed when unloaded. Solution - lower expansion rate a lot - sometimes no solution while keeping the glaze looking the same.
#3 Glaze settles quickly and hard on the bottom of bucket. Solution - change some materials to help keep the glazes in suspension - sometimes an easy problem to solve.
Ron has been fixing glaze and clay problems for 30 years with remarkable success. References are available upon request.
