Superfest, chemically strengthened glass
In the east, these used to be in bars all over the place. Bars loved them, because they rarely had to be replaced. The only problem: customers had way too much fun throwing these glasses onto the floor and watching them not break… Until they eventually did, because everything breaks at some point.
The article also mentioned soulbottles, which is modern recreation of these east Germany glass cups.
Very cool.
I’m not finding any claim of superior durability on that site. The statements about material say that they now use more recycled glass and have reduced emissions by 75% compared to the original soul bottle. All of which makes me doubtful that they are still using the Superfest process.
But maybe I just missed it, or they’re actively hiding a major selling point for some reason.

This is the only conclusion I could come to as well. They have it on their kickstarter, but not on their website, which is full of hippie stuff (neutral) instead for some reason. The old version didn’t use the process, and the new version does, but only according to the kickstarter about it.
I have a low tolerance for inconsistent messaging like this. Sketchy
Looking at the updates posted on their kickstarter, they’re saying the project failed and the brand has been taken over by a different company https://www.kickstarter.com/projects/paulkupfer/ultraglass-stronger-and-lighter-bottles-with-ion-technology/posts/4480077
Oh sad. But yeah, not buying that!
I looked them up on eBay, and found a pair of taller glasses for $99, and a pair of smaller ones asking $60.
They’re pretty cool looking. I’d love some, but not at those prices. It’s seems like a good opportunity for someone to reproduce them.
