Jammed Biscuit 2

I had been making pots chiefly for the entertainment of holiday traffic,i.e. in a suitably leisurely fashion,but the numbers of pots still built up [it's been a long holiday period], so,with my gas kiln out of commission,I decided to fire everything in the electric kiln. The pots were all cylinders of one sort or another,and therefore lent themselves to tight packing. With the same pots in a glaze firing [they're all for crystal glazing] I can only get 6/7 in. And yes,that last cylinder was fired on its side as shown.
For those to whom it is important or relevant- I am happy to inform you that Sydney has returned from Canada
