I'm working on a repair of an old table. the wood is mahogany, the real stuff. the finish is shellac. I did the repair to the wood parts and started into the finishing.
I mixed up a batch of shellac from some garnet flakes I had, but it didn't completely dissolve. the liquid turned the right color, but the partially softened flakes remained floating around in it, and a test drop of it remained gummy for days. so off to the store to buy another $25 ounce of bug spit.
got the new stuff. mixed up a batch. it was completely dissolved in under an hour. all's good, on with padding. got a few rounds padded on last night and went out. got in late, went to bed. got up this morning, went out to the shop. the surface was nice and hard, so I proceeded with another round. went well, and as I was closing up the pad in a ziplock baggie and putting the parts in order I noticed that the jar of shellac has what appears to be solids settling out in the bottom. hmm... a shake... no change... get a stir stick and give it a poke. it's like a mass of stiff jelly at the bottom of the jar. I got it free of the jar bottom and shook it some more, but it doesn't seem to be wanting to go back into solution.
what gives? was I just way wrong on my mix proportions? I just sort of guesstimated, an inch or so of flakes in the bottom, the jar full to about 3 inches with alcohol. I even went and bought a fresh can of alcohol for this one...
