Here is a set of 6 maple coasters that we have done the fractal burn to and then added a Cobalt Blue color epoxy to the burn area. Each coaster is 3 1/2" square.
After you are done using the coasters, put them back together, if you can, to form the set pattern that the fractal burn created. Set the set on the table top, bar top or hang on the wall as a piece of art.
The set of coasters is finished with a food safe, wood preservative which will help protect against any liquid that may come in contact with each coaster.
