Marking glass for identification

[Brew Matt]

I am looking to put some sort of identification mark on some glasses on the underside so it doesn't detract from the glass itself.

I think those dymo type stickers or marking pen will just wash off. Worried about engraving in case a crack develops.

Any suggestions on how to do this would be appreciated.

Try using etching paste. You can get it from Spotlight

Acid etching kits are available from art supply stores.
They work well.

A Dremel equipped with a diamond bit.
And a steady hand.

Second tugger (ergh that sounds awful)

My wife does acid etching with her jewellery. Looks awesome.
edit spelling.

Be "very" careful of the etching creams - they have an ingredient that causes seriously nasty issues.

Glove up - be careful - and avoid any skin contact.

Having said that - they (etching creams) do a great job on most glasses (some glass resists the etch more then others)

A decent engraving shouldn't crack the glasses, I've done plenty at work and never broken one
