It's best to use epoxy resin glue. Generally, there are two components. Now use them together. Apply a little external force after bonding, such as winding with thin wire (don't wind it at the bonding place), mainly to apply force to the joint. Let it dry thoroughly for a few days before use.
Use AB double glue and epoxy resin glue. Pay attention to the need to leave it for a period of time after gluing, and let the glue dry completely before taking it. Use the method of fracture bonding to see if it can be completely bonded, and the cracks that can be bonded are better handled.
If the jade is broken, it can be glued with AB double glue. However, there are traces of re-adhesion after the jade is broken, and there is no way to restore it to its previous appearance. If you want to restore the original state, you can go to the jewelry store to rebuild it. If you don't want to change to another style, you can let the jewelry store professionals inlay it.
You can go to the hardware store to buy AB double adhesive and epoxy adhesive. Don't take it in time after sticking, let it dry thoroughly for a few days before taking it. Other repair methods: broken bonding. The fracture of jade is also repaired by gluing in modern times. Repaired well, even "shoddy".
