To be as similar as possible to the old G-200 feldspar, Laguna Clays blended 3 parts Minspar and 7 parts G-200 HP to produce this material.
However G-200HP was then discontinued so Laguna Clays began importing Mahavir Feldspar from India.

Old Blend Feldspar. What is that?

Old Blend Feldspar. What is that?

Laguna Clay sells a substitute for the no-longer-available G200 feldspar. G200 HP is higher in K2O and lower in CaO than G200, Minspar is an ideal addition since it's K2O is much lower and CaO much higher. A 7:3 G200HP:Minspar mix produces a chemistry that is remarkably close (on paper) to G200. They label this blend "Old Blend". They also list a product called "New Potash" in their pricelist, that is G200 HP.
