Terra Sigillata

 

                                                                                                       

  

So these three bowls were moulded with a pinch technique and then fired in an outdoor sawdust firing with terra sigillata glazing and iron, zinc and copper oxides. It's a technique used and taught by philadelphian ceramicist Jimmy Clark. The surface feels like ebonite, which I quite enjoy and favour over the usual rigidity of high fired pottery. The oxides generate the colours auburn, green and yellow. Black patches are created by soot (that doesn't rub off by the way), clean spots appear white. After an overnight bath in vinegar.
