Clay Bodies<br />
Suitable clay bodies remain an ongoing problem for many reasons. Probably the most comfortable<br />
firing range for these glazes I use is around Cone 3. <strong>The</strong> best bodies for this are fine earthernware, or<br />
terracotta w ith sli ps. I am pinning my hopes on the new high bisque regime with PB 1 03. At cone 4/5<br />
Walkers Mid-Fire works very well and as I soak for 2-3 hours at about Cone 3, this has produced good<br />
results for teapots, beakers etc. I no longer use a special fitted glaze inside these wares as I don't like<br />
the change <strong>of</strong> surface and colour; plus I ran into internal/external glaze fit problems, particularly with<br />
teapots.<br />
I keep all the bubbled, glazed pots until the end <strong>of</strong> a run when I refire them w ith one or two sprayed<br />
coats <strong>of</strong> the glaze set up to a near gel with CMe. In fact, I now glaze all pots by dipping, fettling and<br />
then spraying with two coats <strong>of</strong> CMC set-up glaze.<br />
Kilns need to be well ventilated, preferably outdoors. In my experience, reduced lustre requires levels<br />
<strong>of</strong> reduction beyond those usually used, <strong>of</strong>f the scale on an oxygen probe.<br />
