Bisque firing

Bisque firing


"Nearly ready for bisque firing"Been working hard to fill the kiln and very excited to be nearly ready for the bisque firing!
This is the first firing when the clay forms are heated to drive off water and change the clay physically and chemically into the permanent hardened structure which can no longer soften and change shape. The process is started gently, gradually heating up to temperatures just under 1000 degrees - the faster the temperature rises the riskier for cracks... Then allowed to cool equally slowly until the kiln can be opened.
The resulting bisque ware is still porous enough to absorb a little water from the glazes which are then applied so they can bond to it in the second higher temperature firing.
Ive been enjoying more sculpture - hand modelling octopus, snails and flowers onto the pots Ive thrown and turned. Nature is endlessly inspiring!
But its a little nerve racking trying to dry and fire them intact- this thinner and more delicate the sculpted additions to the pots, the more likely they are to crack or break off...
Fingers crossed and 129310 and 129310 and 129310
