Arrange the broken cup handle correctly, like you were trying to fit a puzzle together. Apply a thin coat of epoxy resin to both sides of each piece.

When the epoxy resin is slightly dry, start to attach the broken handle together. It is recommended that you work with someone to do this for more stable work. Each time you do this, use washi (painters) tape to secure it tightly in place.

This process may require several attempts. Do not give up and use washi tape to secure it back to its original shape. Leave it for 15-20 minutes to let it completely dry.

Once you are sure it is completely dry, carefully peel off the washi tape and gently sand it with a file.

As described in the previous step, carefully apply mixed lacquer and gold powder over the epoxy resin.

Now your broken coffee cup is reborn as a unique, one-of-a-kind entity!
