Customers have asked us to develop a modification to RO-82 that has finer mesh size grog. RO-82M contains about 3% 48M Mullite, making the body smoother, yet incorporating the necessary grog for stability. Other firing and glaze fit characteristics of the body are the same as our best selling RO-82.
