Fritted glass is finely porous glass through which gas or liquid may pass. It is made by sintering together glass particles into a solid but porous body.

General

Fritted glass is often disc-shaped, and consists of microscopic glass particles carefully sintered together to have porosity of various sizes.

Porous metal frits are the metal equivalent of fritted glass. They can sometimes be found in drying columns and in various industrial applications.

Maintenance

Fritted glass is notorious for being hard to clean. If a base bath is used, the fritted glass should not be left in it for more than a day, as the base will begin to dissolve the glass bonding between the fritted glass particles. A strong oxidizing solution, like chromic acid, aqua regia, or in extreme cases piranha solution can be used to remove even the most persistent stains. They are one of the few reagents that can destroy graphite, which is known to be a nightmare to remove.
