I would like to fire with slow cool 2 pieces with Randy's Red (using special RIO) and several more glazed with various Amaco Potters Choice layered. Should a slow cool affect the Amaco glaze? I'm using a variation of MC6 cooling cycle that also cools from 1800F to 900F. I did a test last week with Randy's on a normal firing cycle and it turned out pretty nice. Just would like to get a little more red. BTW also put a wash of RIO over the glaze. Anxious to see what happens.

I'll answer my own question. Success!!! This was my first firing with Randy's Red (see pic) Three heavy coats and a brush coat of RIO (special) mixed with water. The Potters Choice glazes did well also. A little more running where overlapped, but I had brushed pretty heavy for the second glaze. Firebrick overlapped with Lustous Jade on the goblets (a bad picture) Iron Lustre with a touch of Firebrick on the edge. Cone 6 hold 15 with slow cooling from 1800-1300 then slow till 900. Dont' think I need this much cooling next time. Will try slow 1800 - 1300. Firing took 17 hr.

(next time I'll make the pics smaller, still learning)

I am truly likeing that coffe cup. I am working on fine tuning my cooling also. Would you mind giving more info as to what you call 'slow' from 180* to 1300* and then 'slow' to 900* That is a long glaze firing. I drop 500*/hr from peak ^6, down to 1800* soak for 20 minutes,, then 125*/hr to 1650* then off.
I am using the MC6 glazes and getting good results except for reds.

The coffee cup's not doing it for me... the bowl is nice, though. Keep it up!

I call it a soup mug or chili mug. My coffee cup is whatever cast off cup(read just before I take a hammer to it) I have handy.
