For a two-part putty epoxy, knead equivalent parts of each color into a ball until the colors mix entirely. Place a small item of the putty between the rocks; after that, push the stones together. When using incredibly adhesives or special jewelry adhesives, apply a adhesive dot to bond a tiny area or glue lines.
Small to Medium Stones
Glue together a series of small stones using a jewelry and metal adhesive, a “super”-style glue, or a liquid, putty or paste epoxy. If you require a clear bond, opt for a clear jewelry adhesive, a super glue or a clear epoxy resin.
