Bohemian Tango Glass?

Having seen Czechman's Bohemian red Tango glass ashtray, I wondered if these were also Bohemian red Tango glass made for condiments? Metal is silver plate, would probably date from the 30's looking at the style of the set, but not 100% sure. Bought these at auction yesterday too! Like them very much, will be on the table today after a bit of sprucing up!! Thanks for your interest!!
