Blistering Effects

  • Materials - Fluorspar

    Fluorspar generates gases that can produce vivid blistering for special purpose effects.

Crawling

  • Materials - Magnesite

    Magnesium carbonate is commonly added to glazes, especially at low fire, to make them crawl (it shrinks and cracks the glaze layer at the low end of firing and then its high melt viscosity pulls the glaze melt into islands). This often produces dramatic visual effects, especially if the crawling glaze color contrasts with the underlying body or slip. Additions vary from 10-30% depending on the host glaze.

Texture

  • Materials - Bone Ash

    Bone ash encourages strong glaze textures; however, too much can produce crazing or blistering.

  • (Glossary) Slip Trailing

    A technique of adding a relief pattern to a clay surface by trailing lines of slip (clay in thick paste form) using a tube or nozzle (like cake decorating). The raised lines and strokes are often colored and create a surface that is both visually appealing and tactile. Slip trailed lines are often a...
