Salt glazing is a pottery technique that involves introducing salt vapor into the kiln during firing to create unique surface effects. While salt glazing offers distinctive visual qualities, there are several drawbacks associated with this process.
The introduction of salt vapor creates a highly corrosive environment within the kiln. This can lead to accelerated wear and tear on kiln components, including bricks and metal parts.
Excessive salt release during firing can contribute to air pollution and environmental concerns. Proper ventilation and filtration systems are necessary to mitigate these effects.
The outcome of salt glazing can be challenging to control, resulting in variations in color, texture, and surface effects. This unpredictability may not align with the artist’s intended design.
Glaze Fit Issues:
Salt glazing can lead to glaze fit problems, such as crazing or shivering, due to the rapid cooling and crystallization of the glaze surface.
Despite these drawbacks, many ceramic artists continue to explore salt glazing for its unique and visually captivating effects.
