What glazes don t need to be fired?

While traditional glazes require firing in a kiln to reach their desired appearance and durability, some modern glaze alternatives do not require firing and can be used for decorative purposes on clay surfaces.

Non-Fired Glazes

Non-fired glazes, also known as cold glazes or non-fired finishes, are formulated to provide a glossy, transparent, or matte finish without the need for firing. These glazes are suitable for:

  • Decorative Pieces: Non-fired glazes are often used on decorative ceramics that will not come into contact with food or water.
  • Mixed Media Art: Artists may use non-fired glazes to enhance mixed media artworks that include clay components.
  • Temporary Projects: Non-fired glazes can be applied to temporary projects or prototypes.

Application and Curing

Non-fired glazes are typically applied to the surface of the clay piece and allowed to air dry or cure. Some non-fired glazes may require additional curing time or a sealant to protect the finish.


It’s important to note that non-fired glazes do not provide the same level of durability, water resistance, or functionality as traditional fired glazes. They are not suitable for functional pottery or items that will be exposed to moisture or heat.


Non-fired glazes offer an alternative way to add decorative finishes to clay objects without the need for kiln firing. However, they have limitations in terms of durability and functionality, and their use should be carefully considered based on the intended purpose of the ceramic piece.
