Featured Late 1700s Air Twist Ale Glass

I'm new to this type of glassware. I'm trying to figure out what kind of twist this is. It's a double twist, but are both twists glass or does one look like glass and the other cotton? Thanks so much, Janice

 

All-glass...one threaded, the other matte finished.
Looks like a very skilled technique.
Very simple overall, an' Elegant!

 

Thank you!

 

You might want to search on eBay "Latticino" stemware. Although I don't think yours is latticino but it will bring up many similar glasses to give you a ballpark idea of what they are. Also search Air twist Stem. for more similar goblets.
I LIKE them and they are definitely interesting!

 

or .. Georgian Cordial.... or wine glass...opaque twist...

 

DSOT = double-series opaque twist
also 'cotton twist'

Thanks, Tallcakes! I have more of these late 1700s glasses - I think I may have the Jacobite one shown in the article - so this is a great reference for me. I really appreciate it!

 

I think I had a Steuben with that swirl once.
