Color & Surface
Frit, powder, oxides and precious-metal leaf — how colour gets into and onto glass.
Colored Frit
Crushed coloured glass, sieved to a grade, rolled onto a hot gather.
Glass Powder
Finely milled colour for a soft, even wash over the surface.
Metal Oxide
The raw oxide that gives glass its colour, and the chemistry behind it.
Gold Leaf
Gold and precious-metal leaf applied between gathers for lustre.
Grinding Medium
Silicon carbide grit and the carrier that feeds a grinding wheel.

Furnace & Heating
The furnace, the crucible, the glory hole and the annealing oven — the heat the whole studio is built around.
Gathering & Blowing
Pipes, hoses, blocks and pads — how glass gets out of the furnace and into a shape.
Shaping & Tools
Jacks, shears, tweezers, pliers and paddles — the hand tools that turn a bubble into a vessel.
Annealing & Finishing
Kilns, controllers, files, pads and wheels — cooling a piece without cracking it, then finishing it cold.
