Oxide Glaze Set — Three Colours

Three oxide glaze bottles in cobalt blue, iron red, and manganese black arranged on a workshop shelf
Glaze is where pottery stops being functional and starts being expressive. I picked up my first oxide glaze set expecting neat, predictable colours and got something far more interesting — surfaces that shifted and pooled in ways I had not planned. An oxide glaze set is the tool that turns a competent piece into a distinctive one.

Oxide glazes have a longer history than almost any other technique in pottery — iron oxide was colouring pots in China three thousand years before the first Canadian studio potter ever opened a kiln. The chemistry is ancient but the results remain endlessly variable, which is precisely what makes them compelling for amateur potters who want surface finishes that carry a sense of depth and movement rather than the flat uniformity of commercial coatings.

What you receive with this set

The set contains three 250 ml bottles of oxide glaze: cobalt blue, iron red, and manganese black. Each bottle is sealed, labelled with the colour name and recommended cone range, and filled to the stated volume. A product information card is included with application guidance — recommended layer thickness, brushing versus dipping, and a note on how each oxide tends to behave at cone 6 temperatures. The glazes are formulated for use on stoneware and suitable for electric kiln firing.
  • Three sealed 250 ml bottles: cobalt blue, iron red, and manganese black oxide glazes
  • Product card with cone 6 application guidance, recommended thickness, and firing notes
  • Formulated for stoneware; suitable for brushing or dipping application methods

What to know before applying

Oxide glazes are sensitive to application thickness — a thin coat and a thick coat of the same glaze can produce noticeably different surface results after firing. Test tiles are strongly recommended before committing a finished piece to a full glaze application. Shake the bottle well before use and stir the glaze in the container during application to maintain consistency. Keep bottles sealed when not in use to prevent evaporation. The glazes are not food-safe without a separate clear overglaze application — refer to the product sheet for guidance.

After hand-over and the defect window

The 30-day defect window covers the physical condition of the bottles as delivered: seal integrity, correct labelling, stated volume, and absence of contamination. It does not cover variation in the fired surface result, as firing outcomes depend on kiln temperature, atmosphere, application thickness, and clay body — all variables outside the operator's control. The product card provides a fired sample reference, but the result on your specific piece will reflect your specific kiln and application.
