In the gas kiln I fire the pots that are glazed with carbon trap shino glazes. I use a variety of these very distinctive glazes – but mostly I make use of a recipe that I gleaned from an American potter called Dick Lehmann. This is a rich and dramatic glaze covering the spectrum from amber to charcoal and is incredibly variable. Remarkably, it is profoundly affected not only by the atmosphere in the kiln but even by the weather on the day the pots are dipped in the glaze. Owing to the sodium carbonate in the glaze, it crystallises as it dries. On a very hot day this crystallisation process creates unusual striated, rippled effects on the glaze. After fifteen years spent exploring (perhaps obsessively) the possibilities of carbon trap I am still surprised by it. Even perplexed. But it is sometimes so beautiful that I keep pursuing carbon trap perfection.
Method:
Pots bisqued, then dipped in glaze.
Decorated with liquid wax emulsion, iron rich ash glaze, globules of ‘sang de bœuf’, sprinklings of rose ash.
Fired to 1280 in pretty fierce reduction (from 885C).
Liquid gold lustre brushed on rims after firing.
Pots fired once more to 730 C.
