If you are abrasive etching glass awards, you already have the equipment and materials you need to etch on marble, and suppliers are offering marble plaque kits that have everything else you need. It is a simple matter to expand your offerings so your customers have something new to select from, and it will only cost you the price of stocking a few of the plaques in different sizes.
The plaques are available in several standard sizes like 6 X 9 inches and 8 X 10 inches, and include a flat, polished piece of marble (usually green marble), a nicely finished wood frame, and hardware for hanging the finished plaque on the wall. All you have to do is do the etching.
