Terra sigillata crackle.

One of my latest pots. After smoking in a sagger to 600 deg c. I got the crackle effect to stand out a bit more. Had to open the sagger to re-oxidize a bit as it was to dark. Re-oxidized at 400 deg c.

Oil spot glaze.

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 !!
