Galvanic corrosion

Stained Glass Windows: Managing Environmental Deterioration, published by Historic England in 2020, defines galvanic corrosion as: ‘Metal corrosion resulting from the current flow between two dissimilar metals in the presence of a fluid able to conduct the current (for example, water containing dissolved salts). The type and the relative surface area of the two metals determine which of the metals corrodes, and the degree of that corrosion.’
