How can I repurpose broken glass, plates, & pottery I saved for years?

Stepping stones made from cement. These pieces can be added to the top layer.

Make them into beautiful art like this : https://www.hometalk.com/diy/decorate/rooms/left-over-broken-glass-mosaic-art-piece-6874465

Make a beautiful mosaic!

Use them as mosaic tiles! You can tile a table top, garden stepping stones, picture frames, lot of things!

Thanks for the link & suggestions- very cool. I had considered that but a lot of the pieces are not flat so would needs to be broken really small to lay flat. I thought about covering a plant pot but not sure what would hold the pieces on securely.

Chopped up pieces and those that don't lay flat will give your final piece character and will make your design much more interesting!!! Just not on stepping stones---it could cut someone's feet!

I have seen people mention E6000 glue (small tubes) and locktite Power Grip (large tube) for adhesion. Any other suggestions? Also, will grout hold up on a vertical surface like a planter?

Thanks!
