Crystalline Glazes
[back]
Crystalline glazes are a very cool way to complete a work.
They do need a soak at around 1250 degrees C, so they won't work on all bodies.
The photos on this page show some of the test pieces I made for a Materials Science project.
This glaze used 2% Nickel Oxide as a colourant. The large crystals are zinc silicate. The very small crystals were identified as tridymite.
Below are some of the optical microscope photos (scanned - but didn't come out too well).
These photos are of various samples made during the project. Some are of a 2% Cobalt Oxide coloured glaze, the rest are of glazes using 2% Nickel Oxide as the colourant.
