Carefully!

Seriously, if you are intending to do this yourself you need to get item called a 'spade bit' or possibly a 'spear bit'. These are designed for glass and ceramic. If you can, I would suggest that you practice as much as you can before trying it for real. If the item to be drilled is important or valuable I would consider getting it professionally done.

This is the sort of drill you need

Possibly even like the one in my link?

Funnel some plasticene around the hole and in that, place some oil.
Then drill away.

I bought a set of spade bits for drilling ceramic tiles last year. I imagined more broken tiles but I was really impressed with how easily they drilled perfect holes through tiles. I'm sure they would go through glass as easily - after all, they are designed to do just that. Being careful is the key though Groupie!
