What are the disadvantage of using silver?
Unlike pure gold, silver will eventually tarnish and go dull. Silver can be cleaned of tarnish by soaking for a few minutes in a mixture of half a cup of white vinegar and 2 tablespoons of baking soda. Afterwards, rub the silver gently with a soft cloth. Or, on silver jewellery, use a dry soft-bristled toothbrush or similar.
