Project Proposal: Ceramic Tangrams

I have been working with the geometric shapes for a while and came across the idea of making ceramic Tangrams focusing on the line between play and fragility of the ceramic material. 
Older antique tangrams are beautifully carved and exquisite, made out of ivory, wood, jade, clay etc. But today most of them are just blocks of wood with different colours. I have been looking into different glazes and thinking of different ways to create this fun yet challenging ceramic blocks.
While I am hyper excited at the idea of making tangrams, a part of me wonder if it is considered 'art' to create something that is old and classic. What new stuff would I bring to the table? where is the line between art and design. Can well crafted design and marketable items still be considered art? It brings back to the whole Fontana and Melotti article where stuff made to be used in the home can still be classified as art or do they just become industrialised objects?

While some of us know about tangram, here is an interesting and brief article summarising tangrams, it's history and how it has come to be the world's first puzzle craze.
