By heating alkali silicates under CO 2 at high pressures, alkali carbonates are reformed to an extent depending upon temperature, pressure, and chemical affinity. The CO 2 thus existing homogeneously dissolved in the glass, and other anions and oxygen similarly dissolved and in chemical equilibrium are termed “melt‐residuals” (Schmelzrelikte). Their importance in planing, coloring, decolorizing, machine‐working, vacuum bulb, and electric‐lamp manufacture is discussed.
