Are clay cups safe to drink from?

Clay cups, when properly made, glazed, and fired, can be safe for drinking. However, there are important factors to consider to ensure the safety and suitability of clay cups for beverages.


Glazing the interior of clay cups creates a protective barrier that prevents liquids from being absorbed into the clay. Ensure that the glaze used is food-safe and suitable for drinkware.

Firing Temperature

Clay cups must be fired to a sufficient temperature to ensure that the clay vitrifies and becomes non-porous. Proper firing is crucial for creating a functional and safe drinking vessel.

Surface Inspection

Thoroughly inspect the surface of the clay cup for any cracks, chips, or defects that could compromise its integrity or harbor bacteria.

Usage and Care

To use clay cups safely:

  • Wash the cups thoroughly before first use.
  • Regularly clean the cups with hot, soapy water after each use.
  • Do not use cups that show signs of deterioration or damage.


Clay cups that have been properly glazed, fired, and maintained can be safe and enjoyable for drinking, offering a unique and artisanal drinking experience.
