If you're going to DIY, your tile manufacturer will specify the best materials for installation, generally a modified setting material.
When adding a glass tile accent in a section of stone or ceramic tile, choose tile that's the same thickness for the easiest installation.
Because of the way they balance each other, glass tile paired with wood lends a rich look.
The safest way to clean glass tiles without scratching them is with a 50-50 mix of water and vinegar and then wiping with a cloth.
Consider covering a whole wall (or entire bathroom!) in glass tile for a spa-like look.
