Same Pot



Yes this is the same pot I posted photos of earlier, once in the burnished leather hard stage and the other in the bisque fired stage.

Burnishing the pot in its leatherhard stage gave it a smooth shiny surface and it retained that surface after the firing, but to give it a higher gloss I polished the pot with a bit of paste wax.

One thing I learned after the firing was that the copper carbonate if applied directly to the pot during the "loading" stage will mar the smooth shiny surface. You can see the greenish powder sprinkled on the pots in an earlier post and if you look closely at the top rim of this pot you'll see the effects of the copper carbonate.

In this first firing I also only had two burnished pots. The rest were unburnished, and although they had the same beautiful flash marks from the fire, the surface was rough and had a mat finish.
