MB2 Speckle  (Mac’s Buff Stoneware Speckle - reformulated) 10kg
 
PRODUCT INFO
 
Our newly reformulated Mac’s Mud Speckled Buff (MB2 Speckle) 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 Speckle has a few key differences compared to the original Mac's Speckled Buff:
- White speckle has been removed due to sourcing issues
- Slightly higher shrinkage
- More vitreous at cone 6
- Increased thermal expansion for improved glaze fit
 
Note: Due to the more vitreous nature of MB2 Speckle, firing above cone 10 may result in warping or bloating. We recommend testing for your specific application.
