Some simple bonding compounds using superglue and various powders. Wear appropriate PPE when playing around with superglue. I like the idea that some simple repairs can be made with commonly available ingredients....which reminds me...I have a self watering trough to repair...cinnamon might be involved I wonder whether curry powder would work similarly?
No eye protection... Amateurs!! Neat idea for modeling small items or doing emergency repairs! Maybe some release agent like silicone spray would help with removal from the molds.
