VDB emulsion needs at least 1 day of ripening period before usage. If
not, you'll loose the image in wet processing...

You should be able to make a good VDB by mixing the three separate
solutions, tartaric acid, silver nitrate and FAC, mixing them in the
usual manner and then coating your paper straight away. I have never had
any trouble with precipitates and have not needed to wait for things to
mature. I buy my own supplies from European chemical suppliers such as
Sigma Aldrich or Johnson Mathey as the on costs are less... I believe
that there are branches of such companies in Turkey.
