The greenware is loaded onto kilns, and fired up to 1300 degrees Celsius for more than 12 hours, or called bisque firing. Vitrified and now having a bisque finish, the items are no longer porous. The process ensures that products do not leak nor absorb moisture. Items are again polished through sanding and grinding for an even smoother finish.

If items require glazing, color is first applied before the glaze and once again fired at 1100 degrees Celcius for about 8 hours. Cayana products only use transparent glaze that have passed international tests for lead and cadmium.
