What does 14k ty mean?

I found this question in the Gold and Precious Metals category. The karat is a measure of the purity of gold alloys. Gold in its pure state has a melting point of 1945 degrees Fahrenheit. When alloyed with other base metals the melting temperature of the resulting alloy is changed. 18K yellow gold has a melting point of 1675 degrees Fahrenheit and 14K yellow gold has a melting point of about 1550 degrees Fahrenheit. Gold more malleable than any other metal and can be hammered into foil so thin that it is almost transparent.
