Tinned Copper Wire: Boiled with Cream of Tartar and Grain Tin (Spon's Workshop Receipts)

Copper wire tinned without melting any tin: grain tin or tin shavings are boiled with cream of tartar and water, and the copper boiled in the same liquor until tin comes down on it as metal. Spon gives the receipt for copper and brass in general. Here the copper is wire. Not given: how long to boil. Source: Spon, Workshop Receipts, first series, p. 336. Picture: the receipt.
