PSH 540i slip is vitreous stoneware which fires to a deep brown-black at cone 6. When bisquing, keep items apart to avoid discolouration. Not recommended for
microwave ware; clay becomes hot.
PSH slip is packaged in sturdy plastic pails with a plastic bag liner. There is a $9.00 refundable deposit on pails. Also available packaged in boxes, minimum 20. The charge per box is $3.00 (non-refundable).
