- Wear a wipeable apron, polyester overalls, or similar. Clean or wash frequently.
- Always clean your studio with a wet sponge rather than sweeping to stop dust from becoming airborne.
- When preparing glazes, add the dry material to water, not vice-versa, to minimise dust formation.
- Do not allow eating and drinking in the studio and thoroughly wash hands when leaving.
- Never eat, drink, or apply cosmetics in areas where clay or glazes are handled.
- Ensure emergency eye-washing facilities are available in the room.
- Review official guidelines regarding studio ventilation and chemical management routinely.
In the UK, magnesium carbonate is not classified as a hazardous substance under the GB-CLP (Classification, Labelling, and Packaging) regulations. Therefore, it carries no formal hazard codes. Safe for general handling but generates dust that can mechanically irritate the eyes and respiratory system. Ingestion in high doses can cause gastrointestinal upset.
Dispose of this material in a safe manner and in accordance with local authority requirements.
