Melite-40 is an iron aluminum silicate with traces of calcium, magnesium, carbon, and sulfur. Adding the iron to the glass in a dilute form provides for better mixing of the raw materials resulting in better amber color control. Melite-40 can be used in bulk and weighed directly from a bin, thereby resulting in less manual labor than that ...
