Silicate of potassa and oxide of lead. Examples —Flint-glass, crystal, and slrass. 

Lime.—This substance, which forms an important constituent in flint-glass, maybe introduced either as a carbonate, or slaked or burned. Limestone, however, that contains proto-carbonate of iron, must be excluded from tha mixture for making white glass. The action of lima is to render the alkaline silicates insoluble, and when rightly balanced by the other ingredients, it promotes the fusion of the whole, and improves the quality, but when added in excess, the glass becomes hard and difficult to work, and subjoet to devitrification. 

No compound of potassium with silicon is accurately known but with silicic acid potash forma compounds, which are known as glass. When the silica predominates, we have ordinary hard insoluble glass when the potash is in excess, the compound is called silicate of potash. It is a glassy mass, soluble in water, and the solution has long been known as liquor of flints. (See, hereafter, under the head of Salts, the silicates, including glass and porcelain).

Si(OH)4. When silica, in the form of flint, or fine sand, or powdered rock-crystal is either fused with caustic soda or potash, or heated under pressure with a solution of one or other of the alkalies, an orthosilicate is produced, possessing the formula Si(ONa)4 or Si(OK)4. These silicates are soluble in water, 2nd as they resemble glass in appearance, they are usually named soluble glass. If hydrochloric acid is added to the solution of one of... 

Diamond (D50) described the types of silica that can take part in ASR. They include quartz if sufficiently strained or microcrystalline, tridymite, cristobalite and glass or other amorphous forms, which occur in varying combinations in opals, flints, cherts and other rock types. Opals are especially reactive. Macroscopic, unstrained crystals of quartz appear to be Linreactive but are possibly not completely inert. Some silicate minerals and volcanic glasses may undergo reactions similar to ASR.
