There are many files that I have copied from Stampin discuss forum from our wonderful demontrators that explain tiles. Here is the general break down of all these files in a nice neat outline. I made some of these last night and they are great. The Kyrlon Fixative will allow the tile to not sweat moisture.
1. Purchase marble tumbled tiles from Home Depot. Nine in a box...usually around $6
2. Ingredients:
Black Stazon
Kyrlon Fixative Spray (craft stores)
Stamp set of choice: (like Sun Ripened II also the new Ageless Adornment )
Background set: (example: french script)
Stampin Pastels (work great!)
Sand Paper
Cookie Sheet
3. Wash and Dry tile
4. Lightly sand tile and then wipe off with dish towel
5. With stamp of choice stamp on tile with black stazon
6. Let dry (this is the hardest part)

Just a few minutes of waiting
7. While waiting, us same stamp and stamp on scrap paper, then cut image out
This can be used to mask image on tile so you can use the background stamp.
8. You can increase dry time by using the heat gun
9. Once image has dried, mask with scrap image, and stamp background stamp with
stazon color of choice (some say you can use classic pads as well).
10. Let dry
11. Color in image with stampin pastels
12. Place tile on cookie sheet in 350 degree oven for 15 minutes. This will set the tiles.
Some use the heat gun to dry, that's fine. But if you have several you are doing at a time
then I like to use the oven.
13. Once set, then you can lightly spray the fixative on the tiles.
Done....they look great. For coaster stick 4 little felt dots on bottom. For display use a small
plate stand.
