Gel layer

Stained Glass Windows: Managing Environmental Deterioration, published by Historic England in 2020, defines a gel layer as a: ‘Silica-rich hydrated layer, structurally and chemically different from the original glass, caused when glass is covered with a film of water that leaches out sodium and potassium ions. It represents the first stage in glass corrosion.’
