Making Glaze Testing Cones

Section: Glazes, Subsection: General

Description

A standard shape and size of glaze test is important to be able to compare one test with another, especially over time (so that old tests look the same as new ones)

Article Text

Joe Schmidt, lab technician at Plainsman Clays, has developed a glaze testing cone that is very practical. Perhaps more important, it is a standard shape and size that is always used, this serves very well for comparison and documentation purposes.

Advantages

Steps to make these:

When dipping these in glaze consider the following:
