Investigations into the Crater......

Lava, Crater and Froth Glazes
Investigating unknown territory!

As  you probably are aware by now- this is a blog all about my Raku work. Well, a long time ago -when starting out at Uni,  I first began my work in clay using  stoneware electric kiln firing. This was way before "getting the bug" for Raku in my final year.

I've dabbled a bit with lava glaze effects in the  Raku kiln more recently, and that went fairly well- so I've been doing a spot of research into higher temperature firing with lava glazes and slips.

No harm in that I thought. About 30 glaze tests later and umpteen fired test bowls, it's been "Interesting" to say the least. I quite like the fact that the results are so tactile and yes just like Raku- so unpredictable. The silicon carbide in the glaze and slip- also add a slight element of Reduction-very subtly -albeit nothing like working with Raku. Some of the crater glazes produce huge bubbles which can be rubbed down with a pestle to produce a dry crater surface. All very exciting and at this stage I'm still very much a beginner. But I am beginning to see a future in working with these exciting and unpredictable surfaces- I may just have got the "bug" all over again....

Some more Crater glaze test results

I've been blathering on about Crater and Lava Glaze recipes here and on Facebook too. I suddenly "got the bug" as well as a commission- (more on this later) so hence the rather manic activity testing out glazes and destroying kiln shelves in the process with runny, bubbling glazes.

I tested 2 recipes- after first trying the usual recipes from the internet and in various books. As I suspected - few of them gave satisfactory results- either it was "pilot error" or the glaze authors just happen to neglect to tell you that vital missing  ingredient, kiln temperature or soak time etc! (Know the type of thing?)

Anyway I resorted to testing 2 standard glaze recipes which I've had for years. A turquoise matte and a Lucy Rie white stoneware. The jury is still out on the turquoise variant- but the white is rather nice. A little suggestion from Potter Jan Lewin Cadogan
put me right by suggesting to mix the glaze …

Wobbly bowls

18 years a "potter" and only now can I really say that I can make a great,wobbly rimmed tea bowl!
They're rather fun to do and are achieved by pinching up clay between thumb and forefinger on three sides, then throwing on  and using the edge of a rib to incise patterns in the wet clay. Turning is a bit of a bugger afterwards, but they're getting there...

New work at Galleries just in!

Lots of new pots just arrived at Builth Wells at Erwood  Station Gallery. Also new stock just in at Sota Gallery in Witney.
Goodbye little pots!
