Glass for over tiles behind cooker

[Blonde moment]

I have stone tiles on the wall behind the cooker. Although they have been sealed I would like to put a clear glass splash back directly behind the cooker to protect the tiles further. Can it be screwed on through the tiles?
Would I get the glass from a glazier? Grateful for any advice.

yes and yes.

but tell the glasier what you want it for, also be aware once fitted dirt / dust / grime may get stuck behind the glass (unless you run a seal around it)

Thanks Breezer for quick reply. Did not think of dirt lodging behind glass. What do you suggest as a sealent? Do you mean clear silicone or something similar.
