What kind of slag glass? What is it? Era? Worth anything?
I'm stumped again. Cant find another like it to know what it is besides cute. Light can be seen through the glass between the crimpled edges and center circular area. Approx 5" diameter. Center is just slightly larger than a votice candle-I wouldnt think that was it's purpose. No marker mark that I find. What is it?Any idea when made? Any value? Thanks in advance.
