Gold-plated domes and roofs – their splendour shines into the distance
A dazzling gold dome in the sunlight or at sunset is visually striking and will thrill any onlooker, not just photographers. Very few people know that the gilded domes on churches or mosques, for example, have been shimmering for centuries. The secret behind this long-lasting splendour is gold leaf. No other surface has this kind of durability. Domes and roofs are the best examples of the incredible strength of gold leaf – even in harsh environmental conditions, such as rain, wind, frost or intense sunshine, this wafer-thin gold covering does not lose its brilliance.
Gold leaf outdoors on domes and roofs
Gold leaf is incredibly resistant to sun, water, wind, weather, temperature fluctuations and most freak weather conditions. The greatest danger to gold leaf comes from the physical impact of human hands – but when installed at a lofty height, this is not a realistic risk for gold-plated domes. Due to the temperature, it should be pointed out that external, gold-plated domes and roofs do not need any protective varnish. The brilliance of a gold-plated dome in the light would be diminished by any coating and the durability of the gold plating would also be considerably reduced. Thanks to temperature fluctuations outdoors, the mixtion expands in summer and contracts again when temperatures fall in winter. This causes any varnish topcoat to crack. After a few years, the varnish then comes away from the mixtion with the gold leaf and is carried away by wind and rain.
