GSPT - Frit Softening Point 1170C

Mined in the south-western part of Germany, it is said to be excellent for brown slips and glazes.
Sometimes compared to Albany Slip although it has a little less fluxing oxides, higher Al2O3 and a higher iron content (their datasheet claims 3.3% porosity at cone 04 whereas Albany is close to 20%, 8.5% fired shrinkage whereas Albany is around 2.5%).

The analysis provided by Carl-jaeger.de added up to 101 without the LOI, we have scaled it back to 95 to allow for the LOI.
