Next firing - plans

I plan to fire again within 2 weeks, Friday 21st to be exact. That's the day before half-term and all my tutoring will be finished for a couple of weeks.

I'm going to salt fire this time. I guess once I've done it I'll be salt firing for the next few times as the salt lines the kiln and effects the subsequent firings.

I'm looking at stacking the back of the kiln with my regular glazes, blue, blush, tenmoku and putting some other pieces nearer the front that will get more of the salt.
Also:

- Ash glaze - a combination of local clay and local wood ash.- A basic slip made up of china clay in combination with a variety of ball clays.
- A second slip as above plus nepheline syenite.

Need to order a big bag of china clay tomorrow, seems like I have most of the other stuff.
I'm thinking that I'll gain the effect of the salt and ash towards the front of the kiln near the firebox and that'll get really hot. Further back in the kiln where the temperatures are lower and the salt and ash less I'll rely on my usual glazes. This will mean getting the rear of the kiln up to at cone 9 (1257C) with the front hitting perhaps cone 11 (1293C). There is always some difference in the front and rear temperatures. I'm going to reposition the pyrometer to read at the top of the kiln which will free up two ports, rear and middle through which I can view cones and extract test rings.
