    I did resilver quite a few dials, but the last one does not look that good. I have no idea why some brownish stains do appear after about a day or two even though the dial is already lacquerd. Any idea's what might be the reason for this?

    They usually disappear if you rub with dry cream of tartar. It is a reappearance of copper, perhaps because it didn't dry fast enough. The Cream of Tartar is a ligand with captures the copper in complex molecules. (My understanding from talking to chemists, I'm no chemist)

    I like the dial centre btw, what clock is that?

    EDIT Re reading the original post, I always leave the dial for a few days before lacquering or waxing as those marks can take some time to come through.

    Indeed you must be right, I did not leave it for a time after resilvering, have to get the lacquer off now and start again.

    Yes the clock I did not show here, only the warped part of the base. But here it is, a grand Liverpool longcase clock which will get a nice place in our home ( thinking off it, where in our home :banghead: )

    Ah the one with the damaged panel. Very good, a four hander. Must get quite crowded all that going through the middle! An early moon roller style given the age of the clock too, looks really good.
