Welcome to my blog. I will attempt to make it much more than just a pitiful list of the relentlessly mundane minutiae of my daily existence but if you feel that I have failed try to imagine all the stuff that I haven't posted.

New exciting rocks

The grinding is all done and I have photographed all the successful pieces from my last wood firing. Having survived a truly tenacious cold that struck me down during the Oxford Fair, I have been able to start going through the work - checking codes and assessing what worked and where in the kiln.
This is glazed with one of the new rocks I tried out. It is a pink microgranite from Cumbria. I have been using a pink granite with a very coarse crystal structure from the same area, which gives very stiff glazes that can give a stunning soft chun blue in the wood kiln. From the geology reports I have read I was expecting this small crystal granite to behave in the same way but it is actually very different. It's much more fluid and gives a pale green rather than grey/blue. This piece was in a cooler spot in the kiln with thickly applied glaze and a good hit of ash during the firing.
