Finding carat of gold


#1

Hi all, once again I’m hoping for a little help from all you
knowlegable people out there. My father in law gave a gold crown
w/a solid gold tooth. How do I find out the carat of that tooth? This
is all beyond me, help please! Thank you so much, Lisa

Lisa, Most dental gold is around 16 karat (not “carat” ) If you need
to nail it down closer than that, I’d recommend a gold testing kit
which lets you compare the action of an acid - usually aqua regia -
on a scratch mark of your unknown sample against a scratch from a
needle of known karat. The only thing more accurate would be an assay
from a trusted refiner. Good luck!

Hi, Dental golds vary from about 10 kt. to as high as 22kt. Most
’older’ crowns if cast, are probably 18kt. and if fabricated they are
probably 22kt. Skip
