Though we don't use this technique, it is useful to be aware of it. 14k Gold Fill is not the same as gold plated. There is around 100 times more gold in gold fill than there is on plated wire. Gold filled looks like and usually wears as well as karat gold. Often referred to in the UK as rolled gold, Gold Fill is very hard wearing and unlike gold plating is unlikely to wear off, even with use. Gold-filled pieces must be at least 1/20 by weight in gold to be classified as gold-filled.
