Making Tetrax in GBP, Pondicherry 2010













The piece did successfully get into the kiln.














It was preheated on gas for 12 hours.
Then slowly fired with wood for 36hrs.





When there was colour in the kiln and I could see the piece, I thought Hussh! atleast it did not blow up!





In the last few hours of the firing I could see a crack on the piece through one of the peeps, which did not seem fatal.







Anyway stopped firing at 900 deg C on pyro, a hundred deg above cone O12 dn. frr various reasons.



I waited patiently for the kiln to cool and then opened the door to see several more cracks.

After the piece cooled further we pulled out the car and goosh there were so many more cracks.

Underneath also there were cracks and some of them were connected on the three sides.






The wood of the drying mold might have been the catalyst for this. who knows....




Anyway, the second piece was brought to the kiln and all the wood sawed out.
