Ceramic 'Seahares' V2

Key words:Flow,Corlorful,Gentle,Soft Edge

Glazed with Air Brush -1

I chose to use an airbrush for the painting and borrowed James' airbrush to make a connection with a piece that was not used in the ceramic workshop.

Key Point:

The ratio of glaze to water is roughly 1:2, which makes it less likely to clog.
Control the distance between the spray gun and the piece so that no splashes accumulate.
When spraying, try the best possible strength, but do not spray in one place for a long time, otherwise droplets will form.
Master the strength with short, quick strokes at a time for the most even glaze.
You can use a masking object for a white-out effect, paper tape is recommended.

Test Result-Failed

Because of the thinness of the glaze, especially on the edges, the transparent glaze applied by wetting may dissolve the glaze on the edges.
At the same time, because of the undulating shape, too thick transparent glazes in curved areas tend to form air bubbles.
High temperatures may also cause the glaze to disappear in thin areas.

Small Research

I have found that most of the ones that use glazing material with an airbrush use a on-glaze. You can retain the shape and colour of the airbrush relatively perfectly. However, it is worth noting that the firing temperature for on-glazes is relatively low between 700-900, which limits the choice of clay and other glazes. It also inspired me as to whether colour and form would be better retained at lower temperatures.

Glazed with Air Brush - 2

I carried out three different sets of experiments on the last failed glazing case.

I placed the specimens in

High-temperature without transparent
Low-temperature kiln without transparent glaze
Low-temperature with a thin transparent glaze

Test Result

The reverse colour of the test piece without the transparent glaze does not change much and the gradient edge effect can be retained. The high temperature test piece is more vividly coloured than the low temperature test piece. The colour of the low temperature specimen with a thin transparent glaze is more vivid and the gradient does not disappear.

Glazed with Different Methods

I experimented with different colouring methods and glazes to express the theme.

Test Result

Underglazes still need a clear glaze after colouring for best results. Metallic glazes have an unstable effect when fired and should not be used subsequently.
