I learned a new word today, bullicante, from @Ownedbybear. This reminded me of a new vase I got from the reseller's treasures. I'm not sure these bubbles are tiny enough, though. It is 8 1/4 inches tall and 3 1/2 inches at its widest point. It is very highly polished and heavy. There are no marks on the bottom. Comments, speculations, guesses and anything else will be gratefully appreciated.
My mind is a bottomless pit of mostly nonsense with the occasional gurgle pop sound as a useful fact rise to the top......
Went to the Tacoma ,Wa Glass museum where they also blow glass. They showed how those bubbles are created. They squirt a thin stream solution of water and baking soda while turning the molten glass.
That's one method which produces what's often called soda glass. It can also be done with moulds, rods and other technques. Good thread here: http://www.glassmessages.com/index.php?topic=30417.0
I’ve been there. Lovely. I think they were demoing something else that day. Thanks for the insight into how it’s done. Totally amazing that they can do it so precisely.
Fascinating. Possible exploding pieces if you use petrol around a spark. It’s is very illuminating as it shows why some are cased and some are not. I’ll have to read it several times to grab all the morsels. Thank you for this.
