Appreciate the feedback. Lets me know if I’m on the right track or not. Reach out again if you have any questions. I’m always happy to help. Enjoy making something beautiful for your garden!

Yes. Same side with gems (like the pic in the post) so that it will hang or prop up against window properly. Like if it’s set on a window sill. A dish gives it some dimension that makes it interesting. You can also use seashells, sea glass, driftwood, glass beads (always use glass as plastic ones will fade). Your class can play around with the gems first to see what they like before committing to glue it down. NOTE: Use E-6000 VERY sparingly when gluing the glass to the frame…don’t lay out a bead b/c when the glue shrinks, it could crack the glass! I need to edit my post. I actually had that happen. So just use small dots of glue along the surface. E-6000 is quite strong so it doesn’t take much to bond the glass to the frame.

Exciting! Hope it goes well for you!

Not heard of B7000, but for outdoor use, you always want to look at temperature. All glues are rated for such. Super quick research on B7000 shows 90-C which equates to 194-F, so about 200. That is still a very low heat threshold (though better than E-6000). Some 2 part Epoxy’s are rated at 200. As mentioned in the article, it would depend on where you live and your summer temperatures. If you have prolonged heat, I’d stick with the silicone calk products. They are intended to caulk around the exterior of doors and windows. But you could certainly experiment and discover what works best for you.

As for the mosaic: are you mounting it on the door, or replacing existing glass with your mosaic panel? I do not have enough experience to confidently advise here. I would talk to a contractor or someone in your community that sells glass or works with glass arts. I have heard about those who have used thick glass platters for a transom or green house windows- that the glass is often thicker than the glass panes for standard windows. Many entry doors have glass panels in them that aren’t bothered by ‘vibrations’, so my guess is that if the panel was secure top and bottom and sides…so it’s not swinging loose, it’s probably going to be ok.

I love making garden art, and love being able to help others by sharing knowledge and experience. When I come up against a problem or something doesn’t work out, I attempt to find out why. I also keep an ear out for problems folks experience and in the process, I’ve learned quite a bit as well!
