| ABSTRACT |
|
The study is an attempt to prepare the raw graze can replace the lead glaze that has been used for a long time as Korean Kimchi-jars. 1) The batch of the glaze that show the similar properties and appearance of lead-glaze were 40% of Yongin or Anseong Yakto, 40% of Ash and 20% of Anhydrous-Colemanite. It's Seger Formula was {0.86 CaO 0.02 MgO 0.12 KNaO} {0.26 Al2O3 0.0007 Fe2O3} 0.92 SiO2 0.3 B2O3 2) The firing temperature of selected glaze was 950-1050℃. 3) As the content of anhydrous-Colemanite was increased, the thermal expansion coefficient was decreased. 4) The color of leadless raw glaze was translucent light yellow. It was possible to obtain the same color as lead glaze by Fe2O3 and MnO2. |
