The Glass Alchemy Portland Gray frit is an innovation developed to fill a gap in the borosilicate palette. Before its creation, no gray glass rods were available. Existing gray preforms tended to turn almost white, making it difficult to create realistic pieces like shark sculptures. The Glass Alchemy Portland Gray rod introduced the first opaque gray in the industry, based on neutral #5 on the gray scale.

Portland Gray frit is a glass powder designed for use in glassblowing or sculpture. It is a small-particle version of the Portland Gray rod, making it easier to melt and manipulate. This opaque gray frit is perfect for creating works with deep, uniform gray tones, ideal for solid sculptures or pieces requiring monochromatic shades.

The Glass Alchemy Portland Gray frit is particularly appreciated for its ability to create monochromatic works. Whether for solid sculptures or projects requiring a clean and uniform finish, this frit is the ideal choice.
