1 The damaged teapot should be bonded with colorless, transparent and unchangeable adhesive and mixed with appropriate mineral pigments. After bonding, use a cotton ball dipped in alcohol to clean up the excess adhesive, so as to avoid forming a light film after curing and affecting the effect.

When filling the vacancy, self-made purple sand powder is mixed with adhesive as filling putty. After filling, add color, use Chinese herbal medicines and chemical reagents to make tea dirt, and then wax to make patina.

Adhesives include latex, shellac, 502 glue and epoxy resin. At present, CH-AAA super adhesive is better.
