I raku fired 10 peat slices today, 5 fitted at a time in the raku kiln. I used a mixture of peat ash and glaze medium to brush over them, the same as the text tile. The mixture was added in thin layers with some sprinkled on top. I didn’t sieve the ash but left it chunky. The ware was fired for around 25 minutes to bring it up to temperature.

I layered saw dust, newspaper and smashed (with a hammer) peat crumbs/dust in the reduction bins, when I put the peat slices in I threw peat crumbs over them, which shimmered as it caught fire.

The results – I would like the work to be blacker, which I will try to achieve by completely covering the slices in peat/paper/wood chips. I would like the ash glaze to be whiter, which I will try to achieve by layering the ash mixture and ask sprinkles more thickly. More like the test tile below.

Overall I am happy with the raku firing, happy that the work survived and happy with the blackening and texture.
