Abstract


This eksperiment attempts to solve common problems faced in ceramic finish, finishing
ceramic objects have differences to resolve other matters. Glaze is a type of glass coating that
is applied to coat the ceramic objects, this is an interesting layer to be studied, because the
success glaze applications in ceramics is influenced by many factors. Applications glaze on
ceramic objects have a very high level of difficulty, the difficulty seen in glaze formulas,
application techniques, firing temperature, shrinkage of dry matter and the successful
achievement of color after glaze the combustion process. This research is to determine whether
the clay character has an influence on the success rate of the color will appear. The problem
solving method uses the experimental method, this method is considered more appropriate to
determine the level of success of an experiment relating to material containing chemical
elements.
Clay used is a type of stoneware clay has five classes of characters, clay are as follows:
1. Pacitan soil, wet soil has a reddish color, 2. Singkawang soil, wet soil has a whitish colour, 3.
Sukabumi is a brightly colored ground, wet floor is a beige, with 4. Sukabumi, the dark ground,
wet soil has a dark brown color, 5. Bojonegoro soil, wet soil has a light brown color. color Glaze
five characters shall be applied on the surface of clay are: 1. young Greens, 2. Pink, 3. Greenish
blue, 4. Brown 5. Dark blue.
Character clay is relatively large contribution to the emergence of color glaze in
accordance with the wishes or the plan, especially when using a formula based on the glossy
glaze. Glaze formula will tend to be stable when there is a combination of stain with a glaze
oxide, stable formula can also be found on the matt glaze, because it glaze was close or not
transparent. coloring oxides are very sensitive to the character of soil temperature change is
cobalt and fe ,experiment that required in advance if the formula contains two types of oxide
glaze. Burning with the reduction or oxidation also will give effect to the glaze colors will
appear.
Keyword: experiment, color glaze, characters clay.
