WHY DO WE APPLY A TIN LAYER ON COPPER PANS ?
Known by professionnals for its excellent heat conductivity, copper slowly oxidizes. It gradually tarnishes to a black colour up until it reaches its famous grey-greenish tint. If this oxidation has the advantage of protecting the copper, it can on the other hand be a source of intoxication. This tint is the ultimate degree of oxidation of copper, which is particularly harmful in case of ingestion. This is why it is essential to tin your copper utensils.
Only exception : Jam basins : no tinning required since the sugar counteracts the oxidation, hence a sparkling copper after cooking jam !
L'Atelier du Cuivre offers retinning service for your pieces with two possible finishes, brushed finish and polished finish.*
* Please bring your pans and pots directly to the Workshop so that we can judge the condition and the possibility of repair.
