Important Updates!!! December 1, 2023

Due to rising costs of production we must increase our prices by 6%. The new price is effective January 1, 2024. We apologize for the inconvenience. Thank you for your patronage. 

Thanks for visiting Mackie's Slip, Inc.!

Mackie's Slip in Seminary, Mississippi has been the South's superior earthenware (ceramic) slip since 1968. Mackie Newton created his own formula to produce the best slip around. His secret is printed on every box, "Good Water Makes Good Slip". His son, Heber Newton, now ensures that the quality of the slip stays consistent.

Mackie's Slip has minimal shrinkage and an extremely good greenware strength. Our slip complies with ASTM-D4236, rated NONTOXIC, and is fully compatible with the nontoxic low-fire glazes available from Amaco, Duncan, Gare, Laguna and Spectrum.

When properly fired to Cone 04 maturity, the slip is nearly pure white. Only fire the slip from Cone 04 to Cone 06 to ensure compatibility with all major brands of glaze and underglazes.

Our slip is packaged in 2-gallon boxes, premixed and ready for casting. A single 2 gallon box of slip weighs approximately 30 lbs. A full pallet of Mackie's Slip is 80 boxes (160 gallons), and weighs 2450 pounds including the weight of the pallet.

We are also a leading distributor of Alligator Clay and Laguna Clay.
