The essence of casting is the transformation of space and matter, yet exploring the undefined dynamic boundary from the “mould” is what I have been working on. Establishing connections to the "environment" is how we learn. We always create a confined area as we define things. Just like the Casting itself, the mould exists while constructing the identity. And the definition of the mould creates boundaries. The boundary represents a dynamic connection between restraint and transformation, resistance and symbiosis, identification and negation, self and non-ego, inner reality and external perception. Each step in the casting process speaks of transformation in the dynamic boundaries. Through the exploration of different materials in lost-wax casting, I revisit the definition of "boundaries", the definition of "definitions", the boundary of "boundaries", and the relationship of "relationships".
