I have this gorgeous green heavily salt glazed bottle

The mark looked like Mirek Smisek's .....
until I washed it and now there is not even a remnant of any mark!
What can I use to bring the sunflower mark back.... something dark I would imagine?

This is to remind me to post a pic asap

The bottle ..... and I don't think it is salt glazed any more!
I'm trying out the thumbnail option...... just click to enlarge



the mark ....


This has to have been made by a man with large hands as the strappy handle is very masculine but perfect.
