adding granular feldspar or stone to clay body
If you wanted to make test tiles with 1.5%, 2.0%, 2.5% & 3.0% SiC you could mix up 4 glazes, or you could mix up a 3.0% glaze and "dilute" it with commercial glaze. You can then make a smallish quantity of an x% glaze by mixing 1 volume of the 3.0% glaze with (3.0/x)-1 volumes of the commercial glaze. (I would use a small syringe).
