Kathy had a good question about glazing for single firing.  I took her question and incorporated it into a discussion topic on its own, rather than leaving it here in general comments. Find it under this group as a discussion entitled "Glaze Application for Single Firing".

Ah... so this is where I join this group.  I have posted photos of recent single fire work on the single fire main page.  Should I move them to here? Thanks, Susan

I'm baaack! After doing a load of bisqueware last week, I'm back to single firing. I have a load cooling now. I have noticed with spraying 4 or 5 layers that it is hard to keep the wax on the bottom. It tends to get pitted, allowing glaze to stick and then needs to be wiped which enlarges the pit. I think I need a harder wax. I'm using an emulsion wax that is pretty soft and has a pretty greasy feel.

Sorry Gang, I'm a traitor to the cause. Yes, I'm doing a bisque tonight. Oh! The Horror, The Horror.

Need a reason to single fire? How about this. Sunday I threw 11 pots. Monday evening I put handles on 9 of them that were mugs. Tuesday they dried in front of a fan. Wednesday evening ( I have a day job) I waxed and glazed them and got them preheating in the kiln at 11 p.m. Thursday about 9 p.m. I should be shutting down the kiln. Friday morning about 10 a.m. my finished pots should be coming out of the kiln. That's a five day turn-around from wet clay to finished stoneware. With the added tricks of drying your pot with a heat gun or torch and finish drying in your kitchen oven, you could actually do it in three days!

Way to go George. Everything looks great. Thanks for putting them up so we can see them.

George, it really looks like you nailed it. Love the tall mugs and the jug (form/balance) ...and the way your glazing complements the forms. Bravo.

I'm thrilled with the results of my single fire load from Monday. I've posted the results in an album here on cone6pots.

I'm firing my first kiln load of single-fire pots. The glazing went well with some poured interiors, some dipped but mostly sprayed exteriors. One tankard handle separated at the lower join, but that was the only obvious raw glazing mishap. Using Nutmeg, Variegated Slate Blue, C Harris Temoku, Rutile Matte, Floating Red, Water Color Green, Hannah's Fake Ash Blue, Strontium Crystal Magic White. Doing a slow preheat around 212 deg F to drive off the loose water. Then a slow climb up through 1400 deg F. Regular heating and cooling from that point on.
