MB2

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.
