Mackinac Bridge Copper Coaster

$35.00

These Copper Slate Tiles are all hand made originals and no two are alike!
They are made from acid oxidized on heavy gauge copper using a ten day 42 step process. The copper sits on 3/8" slate and is sealed with multiple layers of commercial grade bar top epoxy. This stops any further oxidation and protects your artwork for future generations. Rubber feet protect your surfaces from abrasions. These weigh almost a pound each! Each piece is Hand made.
