In one form or another, gold has been used for decorative purposes for over 6,000 years. There is nothing quite like the appeal of gold, its glowing luster gives it a unique appeal that has transcended cultures for many centuries. Perhaps it is the fact that it is easily malleable and can be formed into practically any shape. Maybe it is that gold is highly corrosion resistant, safe from most acids and the weather it is the perfect decoration whether in its purest form or as a plating. Gold plating that is used for decorative purposes should typically be at least 10 microns in thickness, however many items that are made for purely indoor use have been plated with layers as thin as 1 micron.
