Dear Karen:
The risk of chemical attack is real but you know what?... I would go for it! I mean, you're talking about saw-cut and unfilled travertine, right?
I don't think that the splatters of acid will eat into the stone to the point of creating a real problem. And even if every 10 years or so it will reach the point that you will have to replace a few tiles (which I doubt), what's the big deal?...
The patina has nothing to do with it. If you want to know what patina really is, Google it!
May I ask you now to please read and e-sign our Statement of Purpose at:

Ciao and good luck,
Mauri
