Where to buy frag tiles?

It's a sedimentary rock, and almost nothing but calcium carbonate. But I suppose your concern is a valid point, so why risk it.

I bought half a box of 2x2 "unfiinish, unfilled, tumbled" travertine tiles in the past from Rona, and use a 2" diamond hole saw(cuts like butter!) to make round disks.

I'm not real keen on travertine since it is a natural stone product, the possibility of metals in it is there. That's a risk I'm just not willing to take no matter how small it may be and no matter how many people "haven't had a problem".

ibve been using the stuff from homedepot for years and have quite a bitin my system with no adverse affects.
