Not reducing in the gas kiln

 We fire our big gas kiln to 1280 and in the last part of the firing we normally do a period of reduction, before finishing off with an oxidising atmosphere. During the last few firings we had a lot of pots spoilt because of the over reduction - the oatmeal/blue glaze had come out almost brown and all the aqua pots had turned red when not needed. Also, we had a large sculpture to fire that someone had given us and didn't want to put it under too much stress, so we decided in the last firing NOT to have any reduction and have got some lovely pots out!

The oatmeal/blue colour has turned out great - blues, lilacs and pale green patches.

It is something we will do more often.
