Silicon Carbide and SCM at Cone 6

SCM (with Iron) plus 0.75% SiC, Jen's Juicy Fruit, Mayco Cinnabar (the red blush), and Water Color Green + 1.5% Cobalt Oxide. Hanna's Fake Ash sprayed a little and a ring around the top (which did not drip at all at Cone 6). The liner for this one is Amaco Smoked Sienna. The clay is Mile Hi Aspen Porcelain.


More images from this firing to come. I still definitely got a reduction look at Cone 6, but not nearly as interesting crystals as at cone 8. I have plenty more cone 6 pots for another round of testing (already glazed).

I lowered the temp of my ^8 firing schedule by 80 degrees (peak at 2140), still used an hour hold, and used a fairly slow (-200 degrees/hr) cool down to 1800. The 6 cone was perfectly dropped and the 7 cone was barely bent. For the next firing, I'll be dropping by -150/hr down to 1600 since I'm going to be using one of the MC6G glazes as a liner.

Update 2/9 - a couple of tumblers from the same firing with basically the same glaze...



Before firing...

(and in a different order)
