    A couple of days ago I mixed some VDB solution. Did the parts in the right sequence, however probably addded them too fast. There is a precipitate in the bottom. Is this ruined or can it be used? Thanks

    Precipitate with VDB is very commonplace. I can usually make it go back into solution by adding a bit more tartaric acid (up to 50% extra(, applying gentle heat and lots of stirring.
