Mother: Gold is alloyed because in it's purest form, it
easily be bent with bare hands, or get scratched or marre
An alloy is any mix of metal with other metals, use to give the material certain desired
properties, like: increased hardness, variations incoloi lower melting points, higher melting
points, or even lower price.
Gold purity content is categorized using the carat syste . Depending on the ratio of pure gold to
other alloys, the gold used in rings and other jeweller is usually categorized as 10k, 14k, 18k,
22k and 24k. We use K or ct or sometimes kt for carat.
The higher the carat, the purer the gold. 24k gold is Iso called pure gold or 100 per cent gold.
This means that all 24 paits in this type of gold are ll pure without traces of any other metals.
22K gold means there are 22 parts of gold and 2 par of other metals.

points, or even lower price.

Gold purity content is categorized using the carat syste . Depending on the ratio of pure gold to

22K gold means there are 22 parts of gold and 2 par of other metals.
