Hi Glowteam! I’ve been scratching my head about this one so I’m putting up the ‘please help’ flag: I’m trying to frost / etch some glass bottles and I’m struggling. I’m cutting the tops and bottoms off and then need to front the entirety of the remaining cylinder so it lets light through but is no longer see-through. One proviso though, I’m keen on an efficient solution as I’d like to be able to produce a bunch of these and I don’t want to use the spray stuff as it’s not great for the environment.
My current idea is to place it in a 4" waste pipe full of silicon carbide grit and stones and roll it for days. I’ve no idea if this will work but I don’t want to make the rig to do it if and waste all the power if it won’t. I’ve also head that acid etching is really effective but it uses HF (which is, rightly, highly restricted) or con Sulphuric (which isn’t great either).
Anyone have any experience which might help me do this quickly, efficiently and with minimal effort . environmental impact?
…now I write it down, it a big ask!
