He discusses also the occurrence of the cuprous oxide layer which is said to have been described by Sage as early as 1779.
Firstly, by no means all bronzes which have been dug up, even though from the same excavation, show the layer of cuprous oxide.
It is soluble in boiling hydrochloric acid, but it is not reprecipitated by water, as is the case with cuprous chloride.
