Zinc oxide influences glaze color more than any other element; zinc already combined in a stain will not harm the color, but free zinc oxide in the glaze can destroy it. For calcium, adding the molecular equivalent of CaO as wollastonite often gives better uniformity – subtract the extra silica it adds, or the glaze surface will suffer.

To compensate for this, Skutt directs more heat to these areas when they design the elements. The fact that we have twice the element grooves in our kilns gives us more design flexibility than some of our competitors.\u003c\/p\u003e\n\u003cp\u003eIt also gives you more loading options since it is always recommended to have at least one element radiating between each layer of shelves.
