Low-iron glass is a type of glass that is made from silica with very small amounts of iron.

Low-iron glass is a type of glass that is made from silica with very small amounts of iron. Iron is in fact what causes a green tint that is visible on especially on larger and thicker sizes of glass. Low-iron glass is often a choice for aquariums, some windows, and other applications where clarity is desired, like frameless glass showers, so that special tile work can be featured without altering the appearance through an unwanted tint. Low-iron glass is also excellent for product displays in the retail environment. It allows the merchandise to shine through naturally.

Low-iron glass is sold under a variety of trade names, such as:

  • • Ultrawhite
  • • Optiwhite
  • • Starphire
  • • Starlite
  • • Krystal Klear
  • • Diamant
  • • Eurowhite

Don’t be fooled by products called Regular Clear Glass. While it uses the term clear, it is not the clearest type of glass available. If you’re looking to have the glass back-painted or coated a specific shade to match your decor, your glazier won't want to use regular clear glass because of the color shift due to the glass quality. All glass does have at least a tiny amount of greenish tint - even low-iron glass. It is impossible to completely remove all of the iron particles. However, low-iron glass is the clearest glass you can buy, and will have far less greenish tint than standard glass. When investing in a beautiful glass shower enclosure, or big picture window that frames a fantastic view, it is well worth it to specify low-iron glass.
