You can use this Glass Cup for a flower pot and other decorations for homes and offices. I use The art-time tempera paint before engraving. I use different settings to get different results for testing as in the uploaded file. So you can know which setting is better for your project. I also test for the rubbing paints. You can see the photo of the Black add, Gold add, and silver add. So you can think about which color is better for your project. Thank you
