Degussa Frit 90208

Description: Very high sodium, boron free, high expansion frit

Oxide Analysis Formula
Na2O 28.89% 1.00
Al2O3 9.51% 0.20
SiO2 61.61% 2.20
Oxide Weight 214.63
Formula Weight 214.63

Notes

Commonly used to make crystalline glazes because of the high sodium and relatively low alumina (Al2O3) contents. However other similar frits have much lower Al2O3.
