Review on Pebeo Vitrea Frosted Glass Marker Painting, Drawing & Art Supplies by Selena Ananth

I have about a dozen different colors of Pebeo Vitrea markers. I work a lot with glass and sometimes you need a little color to highlight an area. It's one of the few products that sticks to glass. I've found it works best on ivory or white. It wasn't as dramatic on a clear glass object. My advice is to check the manufacturer's website. If you only read the side of the pen, you will need to leave the colored item at room temperature for 3 days before it is fully waterproof. The website has instructions for baking at 300 degrees (F) for 40 minutes. Big time saver.
