Didn't know there was grades of silicate, I adjust the thickness of application to get different results.
I have access to two different grades of sodium silicate. The standard ceramic grade which is fairly fluid and an industrial grade that is used to make sand molds for casting iron. The industrial grade has the viscosity of corn syrup and gives a very different pattern of cracks.
The standard ceramic grade gives a much finer network of cracks as shown in the first two photos below.
While the industrial grade gives a much coarser network of cracks as shown in the last two photos below.
I have found that I can adjust the size of the crack patterns by mixing the two grades in different ratios.
Something you might want to look into.
I appreciate the feedback on the pots.
Regards,
Paul
