I have started to use everyday objects in my artworks since 2011. I kept seeking inspiration from commodities in daily life. By bringing in life experiences and imagination, I made installations by abandoning the original practical functions of objects. This artwork Depth is one of my illustrations of the concept I have discussed above. This piece of work not only reveals our way of thinking in post-‘80s but also inherit the manufacture craft of traditional glass. I hope to discuss the possibility of transforming materials and converting values through artistic creation.
