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.
