Dave, Custom Building Products makes a Glass Tile Premium Thinset Mortar, which would be sold by Home Depot, but I don't know if it would be stocked at your local Homer's. Can't vouch for it personally, never used it, but it's specifically aimed at your application.

While the relatively recent ANSI A137.2 publication specifically for glass tile doesn't specify a particular mortar or mortar type, it does note that not all A118.4 mortars are created equal and some may not be suitable for glass tiles. That's almost certainly why MAPEI requires the additional polymer additive for their mortar when used for glass tiles. Some of that may also have to do with the different types of glass and in your particular case where you're not actually bonding to glass, that would add a further complication.

I agree with Goldstein that talking directly with MAPEI (they have a good technical phone line response) about your particular tile might be a good idea.

The A118.10 waterproofing membrane portion of your equation requires nothing more than a modified mortar meeting A118.4.

My opinion; worth price charged.
