Reinstalling used glass tiles

[giddonah]

These tiles were installed with nearly 1/2" of smelly goopy glue (the consistency of play dough) in large patches which had air gaps behind them (kind of like an ant farm). They were installed nearly flush with a paper think layer of some kind of grout sealer between each tile. The backs of the tiles have an almost plastic feeling and have striped grooves across them.

Is there a problem using thinset?

They're all scraped and will be cleaned with chemicals to make them squeaky clean. We begin tiling this week. We're going to try to make it without a grout line. We'll put them up like bricks with mortar on the edges and squeezing them together.
