I am also interested in locating detailed technical on
the process of “tinning”; a plating technique where molten tin is
rubbed onto copper to create a silvery effect.
The simplest method is to use Oatey 95 tinning flux (Homedepot should
have it)

For the heavier coat on copper pots etc . The parts are pickled clean
and the heated pot is rubber with molten tin with a sal ammoniac
swab.

Astrogal Press has a very interesting book on early coppersmithing
which describes the apprentice whose duty was retinning copperware.
It amounts to careful heating and rubbing granular tin on with a
very coarse fabric using sal ammoniac as the flux.
