The frits listed on this page are divided into two sections: The first section is a cross reference of some available frits showing where you can substitute among different brands. The second section shows a breakdown of each frit into the Silica/Alumina Ratio, the Molecular Formula,and a Percentage Analysis. Since these formulas were imported from another file I cannot guarantee their accuracy.
Please note: since there may be minor variances in the compariable frit you
select, be sure to test the frit before using in production.
