Product Details

MB2 Macs Buff

Best application: Throwing and hand building, large and small.

Product Info

Our newly reformulated Mac’s Mud Buff (MB2) is a traditional, iron-bearing, plastic midfire clay body made from 100% New Zealand clays. It offers excellent throwing and handbuilding properties, ideal for both small and large-scale work.

What’s changed?

MB2 has a few key differences compared to the original Mac’s Buff:

– Slightly higher shrinkage

– More vitreous at cone 6

– Increased thermal expansion for improved glaze fit

Note: Due to the more vitreous nature of MB2, firing above cone 8 may result in warping or bloating. We recommend testing for your specific application.

– Mesh size 50

– Dry shrinkage 5-6%

– Cone 6 – Total shrinkage 12-13%, Absorption 1-1.5%
