by the pound:
G-200 Feldspar WAS a high quality potassium / sodium / calcium aluminum silicate ground to 200 mesh for ceramic applications. Carefully beneficiated and controlled for quality, G-200 offers high potash content and lower iron oxide per unit of alumina than Custer.

The end of G-200, followed by G-200HP was an unpleasant shake up for feldspar users. Laguna Clay Company then offered MFEL S3470* ,a 70 part G-200HP plus 30 part Minspar blend. 

The blend provided most customers with a chemically similar product that could be substituted with a minimum of fuss. Before we could say, “Problem solved…”, another product discontinuation sent Feldspar buyers and technicians back to the process of finding a reliable, sustainable, affordable, product with a chemical analysis and qualities similar to our old buddy, G-200. 

Mahavir Feldspar offers a superior replacement, at a reasonable price and a sustainable, available supply. “Another Choice in Feldspar” a comprehensively educational article written by Jeff Zamek and printed in Ceramics Technical, issue #41, 2015 provided information on some other feldspar choices. We thank Ceramics Technical for additional analysis of other products to inform your choice. Please click here for more information.
