The Problem

A quick repair is needed. For example, a brooch loses a stone.

The Glue to Use

A cyanoacrylate-based glue, like Scotch Super Glue Liquid Plus ($3 for .07 ounces), creates an inflexible bond that resists moderate heat and moisture. (This type of glue is not recommended for frequently washed items.)

How to Use It

Coat one side of the break with a thin layer of glue.

Fit the pieces together and hold firmly for 30 seconds. The adhesive will set fully in a minute or so.

Sticking Points

The glue deteriorates if the item is regularly in water or the oven, or used over direct heat.

The joints can yellow and degrade over time with exposure to UV light.

Cleanup

Soak hands in warm, soapy water or nail-polish remover, then knead the glue until it pulls off.

Remove excess glue from an object with a clean cloth and nail-polish remover before it dries, or with fine-grit sandpaper afterward.
