Present Glaze
Current ash glazes usually contain less than 50% wood ash compared to before when the majority of the glaze was ash. The decrease in ash percentage is to give the artist some control over the chemical make up and result of the glaze. Currently, ash glazes are mostly used by artists as a decorative tool, but some still use ash glaze ware. In Korea, the traditional ash glaze composed of only ash and water is used to make functional pottery such as bowls, cups, and teapots. Koreans believe using ash glazed ceramic ware is dramatically safer than using plastic ware because of its lack of carcinogens, cancer causing materials.

Famous quotes containing the word present:
“The technological landscape of the present day has enfranchised its own electorates—the inhabitants of marketing zones in the consumer goods society, television audiences and news magazine readerships... vote with money at the cash counter rather than with the ballot paper at the polling booth.”
—J.G. (James Graham)
