Can You Use River Sand to Make Glass? Good Idea or Epic Fail?

Not every source of sand is ideal for glass making. Some river sand has enough silica content (greater than 95% silica) to be considered true silica sand (also known as quartz sand). For example, sand along portions of the Mississippi River contains high levels of silica, as do some beaches in Florida, such as those in Siesta Key.

Silica Statistics and Information

Industrial sand and gravel, often called "silica," "silica sand," and "quartz sand," includes sands and gravels with high silicon dioxide (SiO2) content. These sands are used in glassmaking; for foundry, abrasive, and hydraulic fracturing (frac) appliions; and for many other industrial uses. The specifiions for each use vary, but silica resources for most uses are

Ironsand, also known as ironsand or iron sand, is a type of sand with heavy concentrations of is typically dark grey or blackish in colour. It is composed mainly of magnetite, Fe 3 O 4, and also contains small amounts of titanium, silica, manganese, calcium and vanadium.. Ironsand has a tendency to heat up in direct sunlight, causing temperatures high enough to cause minor burns.

Foundry Sand: Life of a Casting | Reliance Foundry

Ferrous foundries (those dealing with iron and steel) usually use silica sand, sometimes known as quartz sand. Silica sand has long been used in core making, so switching to using the same aggregate throughout the casting process has made the process of managing foundry supplies easier. Silica sand is the most commonly used type of foundry sand.
