Health & Safety & Disposal

  • When handling powdered ceramic oxides in the UK, you must wear an FFP3/P2 face mask and nitrile gloves to prevent inhalation and skin contact.
  • 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.

Tin oxide is not classified as a dangerous substance for supply or transport in the UK. It has no official GHS/CLP hazard codes (H-phrases). However, the fine dust can be hazardous if inhaled, requiring standard PPE and workplace ventilation. 

Dispose of as normal industrial waste, in accordance with local/regional/national/international regulations.
