This open arrangement doesn't, I think, get more pieces into a given
space, but it does allow the heat to circulate faster and more evenly,
and is besides a great muscle-saver.

The discs can be made of any scrap clay, preferably with added grog.
We make them in all sizes and different thicknesses up to $". They
are grooved, dried slowly between boards, biscuit-fired, and dipped
in kiln-wash. If a student has overdone the glaze and it drips off
the foot, no harm done - the disc can be tossed out. Short of this,
they last a long time, and shelves need cleaning and rewashing only

once a term.
