How do you Reamalgamate shellac?
Use denatured alcohol on shellac, lacquer thinner on lacquer, a three-to-one mixture of alcohol and lacquer thinner on a lacquer/shellac mixture. To reamalgamate the finished surface, apply solvent along the grain of the wood in quick, long strokes; work quickly, and don’t let the brush get dry.
How do you fix an Alligatored finish?
Alligatored shellac or lacquer usually responds nicely to amalgamation (applying a solvent to partially dissolve the finish). Stroke on the solvent with a fine artist’s brush until the finish softens and fills the cracks. Let the finish re-harden overnight, then buff the repair with some paste wax.
How do you revive old shellac?

Does shellac need to be sanded?
You should always lightly sand in between coats of shellac with sandpaper in the range of 320 to 400. Doing this helps the next coat to stick on better, and it also removes any flaws that may have been created in the application process. This ensures that small flaws don’t compound over time.
How does reamalgamation of an old finish work?
Reamalgamation is a grand revival technique that can make alligatored, crazed, cracked, and scratched furniture look like new. Basically, reamalgamation is the near-liquefication of a marred finish so that it dries solid and unblemished. It works like magic, it’s easy, and it can eliminate the need for a refinishing job.
