Chrysanthemum Teacup by G.T. Marsh & Co.

Hi Everyone!

I love this tiny see-through cup. I was given it for free at a yard sale in Saint Helena, California, maybe a couple years ago.

Were these made strictly as art?
Was there ever a matching saucer?
It doesn't seem very practical. Someone warned me if I put hot water in it it may crack.

Does anyone collect these? I don't have any others and feel it should be with someone who collects Asian art or china or teacups.
Also, any special care instructions? I don't leave it in the sun, that photo was to show how thin it is.
