Will I have to pay customs charges? Orders to the US and EU ship with duties and taxes prepaid, so there is nothing further to pay at customs. Customers elsewhere are responsible for any import duties and taxes applied by their country." or "International orders may be subject to import duties and taxes applied by the destination country, which are the customer's responsibility. If your country is not listed, email hello@glost-glaze.com and we’ll arrange a custom order.

Food safety depends on the specific glaze, the clay body, and how the ware is fired. Many of our glazes are suitable for functional surfaces when fired correctly and fully matured, but results vary. Always test on your own clay and in your kiln, then check for stability, cutlery-marking and leaching. Read our full guide here: Food safety in ceramic glazes.

Each glaze has a recommended firing range listed on its product page. Firing cooler or hotter can change colour, surface and fit, and may affect durability. If you choose to fire outside the recommended range, run small tests first on your clay body and kiln schedule. We do not guarantee results outside the stated range or in atmospheres other than those specified.

Our sculptural glazes (White Lava, Pink Lava, Moss, Lichen, Sea Foam, Crawl) build texture and dimension: surfaces that bubble, crawl and shift in the kiln. Our functional glazes give smooth, stable, even surfaces suited to everyday ware.

Yes. All GLOST glazes are lead-free.

GLOST glazes are formulated as brush-on glazes. Apply 2 to 3 thin, even coats with a soft brush, letting each coat dry fully before the next. Our glazes are handmade suspensions, so some settling between uses is normal; mix or shake thoroughly before applying.
