Chinese Bakelite is an "affectionate" term given certain sets by many collectors. These sets test positive to the typical "home" test like that other bakelite and catalin tiles.  However, there are quite a few differences -- Chinese Bakelite has cellulose in the formula,  after sanding these tiles down I have personally observed a "stringy" residue after sanding.  Another major difference in these tiles is that they are carved not "Hot Pressed" like the more common Bakelite and Catalin tiles.  The designs can be very intricate and delicate.  When you look closely at these tiles you will see the edges are often very sharp, the only exception to that are the tiles called "pillow tiles", which have obvious curved edges. 

I hope you enjoy the sets I have up and I will be adding more information to help you differentiate these tiles from others.
