Details
“A silky, tangy kaolin with a soft, mineral-rich melt.”
Sour White Clay from Pretoria is a kaolin-based clay celebrated for its smooth, silky texture and distinctly tangy flavour. Dry pieces are slightly firm but crumble easily, transforming into a soft, melt-in-the-mouth texture when moistened, with a characteristically sour, mineral-rich flavour and a damp-earth, petrichor-like aroma.

Known for its high kaolinite content, it has long been part of regional clay traditions. Because the clay is unrefined and naturally sourced, small impurities may occasionally be present and pieces should be checked before use.
