The Doyenne of Ash Glazes

There are a number of reasons why the subject of ash glazes has been on my mind in recent weeks.  One of the best is that, just before Christmas, I was given a lovely little dish by Katharine Pleydell-Bouverie, one of Britain’s real pioneers of studio pottery.  She was known for the subtly of the colours on her pieces which she achieved through the use of ash glazes.  This little dish looks as if it might have been a test piece.  It is only about 10cm diameter.  Mind you, if my test pieces looked as good as this I would be in Heaven!

The glaze is a very subtle green.  The crazing is interesting as it is smaller where the glaze is thin and larger where it has pooled in the dish.  It has also drawn a lot of iron out of the clay causing a delicious toasted ring.  Every time I look at it, and I do so very frequently because I cannot quite believe it is mine, I think about the experimental ash glazes which I tried for the diploma.  Most of my test glazes are sitting on a shelf in the studio and I begin to wonder why on earth I am not having another go with them because they certainly showed some promise and, given the relationship between my pieces and place, there is a good reason for using local ash as well.  It might give my work something even more.

Probably high time I explored my own ash glaze tests a bit further.

 

Testing Times

This week I have been experimenting with a new clay.  I love the feel of working with porcelain but I would really like to reduce the amount of warp which I get in large pieces so I thought I would have a go with some molochite grogged porcelain.  I confess that the jury is well and truly out over this one.  It came out of the bag wet and floppy but when I left it to dry for a bit it became rather fractious and crumbly.  It was a beast to build with – it felt horrible to the touch and did not really want to join to the found materials at all.  I have gone large because that is, after all, the point and I am going to fire to at least 1230 to see how it behaves but I will certainly need a lot of convincing!

yesterday, at a get together of the Diploma students we were talking about clay as you do at 10:30 on a Friday evening, and a number of my contemporaries have also been having a go with a few new clays.  There were some very favourable reports of a white stoneware/porcelain blend from some and so that might be the next one to try but in the meantime, I am open to suggestions – how do you get a lovely smooth, workable clay with the qualities of porcelain but without the warping?
