A high speed immersion blender is a great way to thoroughly mix up glaze test without sieving, but is powerful enough to break the tiny clumps up far more than slower speed mixing and sieving. This changes how the materials behave in the glaze and can give a totally different result, meaning an immersion blended test won’t necessarily give the same result when scaled up and mixed differently. The temperature you fire to will affect the porosity of your bisqueware, and it will affect each clay differently too.

Where your windows have not been decorated for some time you may find that the areas we make good are to a different shade of paint.
