Specialty Frits


Frit is crushed glass, ranging in particle size from a fine powder to fine, medium, coarse and mosaic. It is made from crushed, screened and cleaned COE tested sheet glass. It is used by artists as a coloring agent or used to created decorative effects when blowing glass or fusing. Often used to achieve the effect of painting on glass.

Metallic Irid Frit

Metallic Frit is to give a silver/gold metallic shimmer in fused work. Doesn’t look like much in the bottle but once fused it will stand out. It IS different from rainbow irid frit. It looks best over dark colors or black to achieve the dramatic multi-layer metallic shimmer. It is available in Medium, Coarse and Mosaic sizes.

Clear Rainbow Irid Frit

Rainbow Iridized adds a mother of pearl shimmer to your fused work. It is made from Iridized glass which has a surface treatment where a layer of metallic oxide is bonded to the hot glass surface just after the sheet forming, resulting in a colorful, shimmering effect.

Red Reactive Frit

Comes in both opal and transparent. This frit works with chemistry and heat to create stunning effects. Red Reactive has elements that will react to the metal content in other colors and create unique color shifts and rings. A normal reaction would be a very thin line in a reddish hue around the added glass embellishments. Reactive Guide – Oceanside Art Glass (oceansidecompatible.com)


(this info from Coatings by Sanburg)

Dichroic coating is made by melting Quartz Crystal and Metal Oxides. These Materials are vaporized with an electron beam gun, and the vapor then attaches and condenses onto the surface of the glass, forming a crystal structure comprised of as many as 30 layers. Dichroic frit is not sheets of glass with a dichroic coated smashed up. It is already frit and then it is coated with a dichroic coating. That means that more of the surface is coated. Approximately 80%. It also comes in colors but the black and the clear are the most popular.
