Yesterday we had yet another firing in our old incinerator - now the barrel/ pit. We were experimenting to see if the pots that we had burnished on the wheel, and before biscuit firing, made any difference to the finished products.
Our results showed it does - they have a better sheen to them compared to the ones that hadn't been burnished first. On both firings ( non burnished and burnished pots )we used the new Renaissance wax and this also improved the appearance of both lots.
The pots we put in were large ones and we also wanted to see if they would survive the direct heat from the flame. They did this too as the photographs show.
This pot was placed in a paper bag. The paper bag was filled with sawdust and seaweed strips.
This pot had copper wire wool wrapped onto it, and copper carbonate sprinkled around it.
This pot had onion skins, pineapple skins and spent ground coffee placed into its bag. It had copper carbonate and salt sprinkled around the outside. We think the salt contributed to a slight spotting of the glaze.
The rest of the day was spent glazing some pots, which seem pretty ordinary now, to fire in our gas kiln. We lit it at about 10 and it has just been switched off now 6.30pm. It has been a slight reduction firing. Once again we will have to wait until tomorrow for the kiln to cool down, before we can have a look at the results.
