Experiments on
some Precipitates of
Metals & semi Metals
By M. de Beunie
This Academician’s design was to inquire whether by the
solution and subsequent precipitation of metals, he could
not discover such colors as might be highly useful in arts
and manufactures -- those which appear to afford the
most durable colours are exhibited in the following table.
