This is really cool and thanks for sharing the details. Now I want to see coke bottle glass effects. :-) https://www.nathanallan.com/product/bottle-base-textured-gla...
That's really interesting. I wonder if you could achieve it by a combination of the glassmorphism effects on my page with some neuromorphism effects: https://www.justinmind.com/ui-design/neumorphism
With a quick google search, it looks like you can find some which mimic the 'coke bottle bottom' shape with shadow and light.
