Coastal or Mountains?

Overview

Objectives/Goals Through this experiment I tried to make successful glazes for potters to use made from materials near my home. Methods/Materials I gathered and processed twelve materials from around the area I live in. I created tiles where each material was applied alone, applied in a 2 part mix with wood ash, and applied in a 3 part mix with ash and local clay. I fired 3 sets of tiles to 3 different temperatures, Cone 3, Cone 6, and Cone 10. Results I found that several local materials or combinations of materials could form glazes, especially at higher temperatures. Conclusions/Discussion Our local materials have a wide range of color and surfaces at different temperatures. Materials from lower altitudes seem to have lower melting points. I am excited for further testing and making pottery with my results.

Summary statement
