Tango glass from Czechoslovakia got the name from a popular Argentinian dance of that period (1920's-30's). I don't exactly know why cased bright colored glass was associated with lively music or costumes. I suspect they were trying to capitalize on a trend by association.
Cased glass was produced well before the tango trend but it was usually decorated with all kinds of enamel application and didn't have the detailed rim (it also did not have the full color range).
These polka dot application pieces stand out as one of my favorites. They unfortunately have so few color combinations- red, orange and yellow are the only colors I have seen them in. The "dots" are smoothed into the glass so another layer (or step) was added; meaning they are complex even though simple to look at. Production steps might look like this:
1-gather dollop of crystal case glass
2-gather color base (in pebble form)
3-gather crystal casing (in pebble form)- Blow bubble
4-apply polka dots
5- shape in a form or mold
6-apply rim band
7-cut and transfer pontil
8-polish rim and set to cool
9-polish (grinding wheel) pontil on the base
This application technique was also used by Jean Beck (German), Reichenbach, and Poschinger
