Mix the
molasses and ivory black in an earthen vessel. In an iron vessel let the
gallnuts infuse in 100 parts
of boiling water for 1 hour, then strain
and set aside. In another vessel dissolve the iron sulphate; in
another,
100 parts of the boiling water. One half of this solution is added at
once to the molasses
mixture. To the remaining half add the sulphuric
acid, and pour the mixture, a little at a time, under
constant stirring,
into the earthen vessel containing the molasses mixture. The mass will
swell
up and thicken, but as soon as it commences to subside, add the
infusion of gallnuts, also under
vigorous stirring. If a paste blacking
is desired the preparation is now complete. For a liquid black
add the
remaining portion of the boiling water 500 parts), stir thoroughly and
bottle. |
