The Glaze Library

Discover the unique glazes and colors that define Finnish pottery, each with its own character and story.

Our Glaze Collection

Each glaze is carefully formulated to create distinct textures and colors. The firing process brings out unique variations, ensuring no two pieces are identical.

Nordic Snow glaze showing subtle white and cream tones

Nordic Snow

A matte white glaze with subtle cream undertones, reminiscent of winter landscapes. The iron oxide content creates gentle variations in tone.

Stoneware

Smoke Lichen

A muted green-gray glaze inspired by Finnish forests. Copper oxide creates the distinctive green hue, while reduction firing adds depth.

Stoneware

Terracotta Rust

Warm earth tones with iron-rich coloration. This glaze celebrates the natural color of fired clay, enhanced with subtle orange highlights.

Stoneware

Basalt Gray

A deep, rich gray with slight warmth. Manganese dioxide creates the dark base, while the firing atmosphere determines the final shade.

Stoneware

Clay Off-White

A translucent glaze that reveals the natural color of porcelain. Perfect for pieces where the clay body's character should shine through.

Porcelain

Birch Bark

Soft beige with subtle texture variations. The glaze mimics the appearance of birch bark, creating organic, natural patterns.

Understanding Glaze Chemistry

Color development in glazes showing various oxide effects

Color Development

Metal oxides create color in glazes. Iron produces browns and reds, copper yields greens, and cobalt creates blues. The firing atmosphere—oxidizing or reducing—affects the final color.

Glaze texture and surface variations on pottery

Texture & Surface

Glaze texture depends on the firing temperature and cooling rate. Fast cooling creates glossy surfaces, while slow cooling can produce crystalline effects. Matte glazes contain less flux material.

Clay Body Pairings

Different glazes complement specific clay bodies. Our stoneware glazes work with robust, iron-rich clays, while porcelain glazes enhance the translucency of fine white clay.
