Float glass, clear, extra clear: what is the difference?
They are different types of glass, among which to choose according to the application: in this article we will clarify
What do you mean by float glass and what is the difference with extra clear glass? Making some clarifications can be useful, to appreciate the quality of a product finishes.
“Float” glass, or “clear glass”, is the most common type of glass and is characterized by the typical greenish nuance, which depends on the presence of iron oxide in the composition. Its name comes from the English “float”, because the production process involves a passage in which the glass is floating on the molten pond.
There is, however, another, more valuable type of glass, called “extra clear glass”. It is a colorless glass, completely transparent thanks to a special treatment that eliminates 90% of iron oxide and the selection, already at the origin, of a particular type of silica, clearer than that normally used.
Extra clear glass is a brighter glass. For its exceptional transparency it is also used when enamels are applied, because it does not alter the final color. It is therefore the ideal choice for furniture and interior design projects, because it illuminates and embellishes the final results.
