Depends on the thickness of the coated layer of gold on the steel,thicker the longer. As for the duration of its lasting,its exposure to moisture and corrosion (air,sweat,oil) and general wear and tear will all influence it.

Depends on the thickness of the coated layer of gold on the steel,thicker the longer. As for the duration of its lasting,its exposure to moisture and corrosion (air,sweat,oil) and general wear and tear will all influence it. A steel object's gold plating should be preserved in Vacuum and not suffer any wear and tare or exposure to moisture and corrosion to last for ever!!

How long the steel oats will last, depends on the temperature of the area in which the oats will be kept. If it colder than normal, they can last up to 6 months, not cooked. If they are prepared, they would only last a week at most.Ê
no, the colour of gold depends of the alloy in it. you can plate it but it will not last very long.
The gold rush in Ballarat lasted 13 years
