Definitely DO NOT use E-6000. I’m trying to envision your project. How are you attaching the tray? Will it sit in the center of the wreath so you can hang the wreath? Does the wreath go all the way around…a full circle, or does the tray sit at the bottom and the wreath arcs from the sides overhead, like 1/2 circle? Are you trying to glue the wreath to the tray? Without details, I’m not certain how to advise. If you’re going to try to glue, I’d use 100% silicone for exterior. It’s thick and stays put. Strong, Water-proof and sun-proof, adheres well to ceramic surfaces. The other recommendation would be to drill two small holes on either side of the terracotta tray and use a heavier gauge wire to connect the tray to the wreath. Hope this is helpful!

I also use the GE silicone glue. I use GE silicone 7X I live in New England and I have kept my garden flowers out accidentally all year and they have with stood both the cold of the winter and the heat of the summer. Best product on the market. I use E 6000 on glass that I want to dry clear GE silicone glue yellows overtime it’s it’s only downfall.

I have always said ‘use what works best for you’. I’m curious though why the silicone didn’t work? But if you have success with epoxy, by all means, stick with that. The most important factor is for the adhesive to hold up in high temperatures if you live in that type of climate. Most of all, I’m glad to see you trying different glues and being determined! That’s the spirit!

Thanks for the suggestion. It may be something another reader may want to try.

Here’s a link to my post about how to drill a plate. It’s very detailed and also contains a video demonstration of how to do it! https://makeitagarden.com/how-to-drill-a-plate-for-garden-art/

Some plates are not drillable…usually if they are too thin (I’ve broken a few myself). Corelle brand is also not drillable. The cracks may be from the E-6000. Glue shrinks as it cures and on thinner glass- particularly if you used a lot of glue- it could crack the glass. I’ve had this happen before with E-6000, so lesson learned. E-6000 is NOT like Elmers; you don’t have to use a lot of it. That’s a lot of torque/pressure on the glass. I would try using thicker glass or using less glue. You might also try silicone (clear) that comes in the squeeze tube. It doesn’t shrink because it’s a caulk and not a true “glue”. Let me know how it goes!
