A secondary flux at both earthenware and stoneware temperatures, Petalite supplies lithium to clay bodies and glazes. It has a highly alkaline response to additions of copper and manganese. Can be added to clay bodies to increase thermal shock resistance and reduce risk of dunting.

Health & Safety & Disposal

When handling powdered ceramic materials, 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.

Petalite is classified as a non-hazardous substance for supply and transport in the UK. However, as a silicate mineral, its dust can be a respiratory and physical irritant, meaning it is legally subject to workplace control limits.

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