Cone 5  B Mix with Speckles. This clay has the same working properties as your favorite B Mix WC-401. This is a mid temperature, smooth, porcelaneous stoneware that  is very plastic and workable. This clay prefers slow drying and ample compression on rims and bottoms to avoid cracks. It's currently only stocked in our California facility and ships from there.
