This is the oil spot cone 6 glaze that is listed in my glaze page. It is a two part glaze with an iron glaze going under the white glaze. Many variations of this glaze can be made by changing the oxides and the quantities of the top cover glaze . Here these pieces were fired twice as the soak time worked out to be to short to produce the oil spot first time around , and as you see i got an oil spot glaze on speed!!! This glaze seems to give different results with any change in the firing cycle and even from kiln to kiln. So keep a note of your ramp up times and your soak times !!
This is a stoneware paperclay body that i used a slab roller and a texture stamp to make. It has been glazed to cone 6 with the following recipe ,—- Porcelain body clay, dry (low temp porcelain 1250c ) 20% / Silica -20% / Wollastonite – 20% / cal bor. frit 5 % / Borax – 15 %/ added 2% red iron ox. and 1% copper carb. The glaze sits well on the body with no cracks but i would like less shine, but not a bad glaze. This was cone six with a 20 min soak. Next time i will add a bit of fine rutil to give it a bit of life.
