Permanent white pen to write on glass?

[PixieHot]

I'd like a permanent white pen to label glass bottles that will (hopefully!) be filled with lovely homemade liqueur. Ideally, I'd like the own to be fine. Amy recommendations ?

pen / Any

They sell some in my local art supplies shop but not sure what make but there are some here

Thanks wonky! I'm having a last minute wobble about possibly using tags instead (so that the bottles could be re-used). Hmm.

IME even a permanent marker will wipe off glass with elbow grease.

Glass painting outliner and put the bottles in the oven as instructed.

You can use porcelain pens, they are dishwasher proof :) u can buy them on ebay
