Silica Sand For Use Under Slabs

Nov 03, 2016Firing flat during glaze firing requires some silica under them, to allow movement. On larger pieces I have also used alumina hydrate, takes less and allows more movement. However, be sure to vacuum kiln afterward. Do not get too pushy with the temps during glaze firing either 250F and hour or so. Programming a cooling cycle does not hurt either.
