POROSITY CODE
Porosity Code

Water triggers the pattern on it as time passes by.
The porosity of the ceramic enables water to be soaked or released while different thicknesses of the pattern emphasize the interaction between water and ceramic in a more visible way.
Molding
In order to emphasize the interaction between ceramic and water, different levels of thicknesses are applied on the surface.
Due to different thicknesses, the abilities of soaking water vary. The contrast of pattern is triggered while the water be soaked into the ceramic. It takes longer for water to pass through the thicker part. The pattern is always changing until the water spreads through all the pores in the ceramic.
Sand Blasting
It‘s harder to manage it because the stencil is easily falling off from the round shape. After trying it out many times, the double layers show their strength to resist the power of sandblasting.
I feel very grateful to be supported by Beuth Hochschule in Berlin when the machine in our school was broken during the time.
Glazing
Glazing
Glazing, to make some part of the surface be sealed. Water can only pass through those unglazed parts, which triggers the appearance of the pattern.

At first, I try to pour water as former experiences, but the effect of water coming out is not visible. To emphasize the effect, I try to pour something that contains pigment. The effect shown here is the result of coffee remaining in the cup for more than one day.
