Revêtements associes :

grès, grès cérame, grès étiré, grès émaillé, faïence, terre cuite, pâtes de verre, émaux, pierres naturelles (marbre, granit, etc.).

This is simply taken from a list of materials that can be stuck using a certain make of adhesive (mortar). I've got all the others, but have drawn a bit of a blank on 'grès étiré'.

I think when it's glass, it's something to do with being 'blown' - but as this is sandstone, could it be 'wind-blown' - as in an arty/rustic type of stone tile? It did get some googles, but I wasn't sure. Thanks for any help.
