Stoneware White Casting Slip


Stoneware slip is packaged in 2-gallon plastic bags, 2 gallons per box.


Note (9.24.21): We have made the decision to cease production and sales of our earthenware and stoneware slip indefinitely. Slip is labor-intensive to produce, requires a great deal of valuable manufacturing and storage space, and is more a regional product due to expensive freight costs. We will continue to take orders until October 15 and will manufacture as we can until these orders are filled. We will refer business to other suppliers such as Columbus Clay, Laguna, and Standard, in addition to local suppliers. Contact your nearest Mayco distributor to order. 




Mayco’s Stoneware Casting Slip is generally buff in color and vitreous at cone 6. Suitable for use in microwaves and dishwashers, pieces that are meant for long-term use are cast with stoneware slip because of its strong durability. Shrinkage: 14 1/2% ± 1% @ C/6. Absorption: <1 1/2% @ C/6. Slip is regularly tested using Mayco and competitor’s glazes for fit and performance; no shivering or crazing has been observed. Glazes designed to produce crackle patterns do so flawlessly. Mayco’s Stoneware Casting Slips are AP certified and conform to ASTM-D4236.
