Deep Forest Green: The Glaze Behind Our Boldest Bead

Deep Forest Green: The Glaze Behind Our Boldest Bead

Green is one of the oldest colours in Chinese ceramics, and one of the hardest to control. The Forest bracelet leans into it fully: a deep, earthy forest green on the largest bead we make. Here is where that colour actually comes from.

Green from earth and fire

Ceramic greens are not pigments painted on; they are colours pulled out of metal oxides by the heat and atmosphere of the kiln. The classic route is the celadon family, where a small amount of naturally occurring iron in the glaze is fired until it turns green. A second route uses copper. In both cases the final colour is decided less by the recipe alone than by how the kiln is run.

The data: A celadon glaze with around 1.8% iron oxide and a trace of titanium fires to a classic green. True celadon needs a minimum of about 1,260°C in a reduction atmosphere. The same iron can read blue-green when fired with reduced oxygen, or a warmer yellow-green when fired in open, oxygen-rich air.

Atmosphere is everything

That last point is the craft. Iron is sensitive to oxygen: a reduction firing, where the kiln is starved of air, pushes the green cooler and bluer; an oxidising firing, with plenty of air, pushes it warmer and yellower. A potter chasing a specific forest green is really managing the air inside a kiln at over 1,260°C — which is why depth of colour, not just the hue, is a mark of skill.

Why 10mm changes everything

The Forest bead is 10mm — the largest in the LUMI range. Size changes how a colour behaves: a deep green over a larger, rounder surface catches more light and reads with real weight on the wrist. Substantial without being heavy, grounded without being loud.

What to look for

On a rounded bead a good green is never flat. Where the glaze runs a little thicker — around the curve of the bead, in the slight recesses — the colour pools and deepens; where it thins over a high point, it lightens. That gentle gradient across a single bead is the sign of a real, melted glaze rather than a sprayed-on coat of paint, and it is why a deep green looks alive in changing light instead of staying one dead tone.

Greens like this also sit in a long line of high-fired Chinese glazes that pull their colour from iron and copper in the body of the glaze itself. The Forest bead is a modern colour in that family — chosen for the wrist rather than the shelf, but made the same way: by fire.

Built for the wrist

A glaze that earns its colour in the kiln also wears well outside it. Once a high-fired green has vitrified, the colour is part of a hard, glassy surface rather than a coating that can flake, which is what lets a single bold Forest bead take daily wear and keep its depth. The craft that makes the green beautiful is the same craft that makes it last.
