This isn't a chalk marker. It's a chalkBOARD marker. Think of it like a paint pen, but instead of regular paint, it applies chalkboard paint. Once you have followed the directions, the surface can be used like a chalkboard, especially with the Bistro chalk markers that SRM is also now carrying.
I experimented with the marker on a glass vase. The marker is not recommended for glass because it isn't permanent on glass, but you can still have a lot of fun creating with it so long as you don't mind the chalkboard being fairly temporary. I have a list of tips for working on glass on the SRM Stickers blog today.
Next I am going to try turning a framed piece of glass into a chalkboard, or maybe a mirror. So many possibilities! And, of course, I'll be trying it out on a layout soon, too.
