TBH, this thread should be moved to Making Stuff Together like other dude suggested. You have no idea how or if this is even possible and you aren't listening to anyone. This isn't an IC. This isn't "hey, I have this product, would you be interested in mass producing it". This is "hey, I have an idea that everyone says is impossible and I don't care, would you buy it?"
You don't have a design, you don't have a manufacturer, you don't have a price, you don't even have a specific glass picked out (there are lots and they all work different).
Lot's of people would likely be interested in glass stems, but before you gather interest in people buying them, you need to prove what you want is even possible. Until you are able to make a prototype, I don't understand the point in running an IC. It's all just hypothetical.
