The technique of making traditional Moon jars during the Joseon Dynasty was combining two hemispherical shapes with the upper and lower parts to create a large, round Moon jar, which was the most suitable method because there was no electric wheel at that time. Also, the plasticity of clay was not as dense as it is now. It can be further emphasised that the act of bursting is a process of overcoming trauma and escaping oppression by bursting a jar, which is traditionally made but horizontally divided into two pieces again.
Breaking one beautiful Moon jar into two pieces again corresponds to my mind's perverse in my duality. But even in that split Moon jar, there are still irises, and It can be seen that there is always hope to be happy inside me.
