Case and Acid Solutions for 10K, 14K and 18K Gold. DIRECTIONS:
10K Gold:
Place a drop of 10K Acid on both marks. If the Gold is 10K or higher, the color of
the first mark will be the same as the second (comparative) mark.
If the Gold piece is
less than 10K, the mark will become fainter and eventually will disappear.
If the object is 8K or less, the mark will disappear at a much faster rate.
Eventually, as you develop experience, you will no longer need a comparative
mark as the rate at which the mark fades will be a good indicator.
Place a drop of 14K Acid on both marks. If the Gold is 14K or higher, the color of
the first mark will be the same as the second (comparative) mark.
If the Gold piece is
less than 14K, the mark will become fainter and eventually will disappear.
If you want to test a 12K Gold object, make two marks on the testing stone. Put a drop
of 10K solution on one mark and a drop of 14K solution on the other mark.
The mark with the 14K solution will disappear rapidly while the mark with the 10K
solution should remain visible but with a slight color difference.
Place a drop of 18K Acid on both marks. If the Gold is 18K or higher, the color of
the first mark will be the same as the second (comparative) mark.
Any Gold that's less than 18K will disappear in less than 30 seconds.
Gold that remains on the stone is 18K or higher.
ALL BOTTLES HAVE IMPRINTED LABELS AND COLOR CODED CAPS.
KEEP IT AWAY FROM CHILDREN AND FOLLOW THE SAFETY INSTRUCTIONS PRINTED ON THE CONTAINERS. We do NOT recommend the use of this Kit to test Gold Coins, as rubbing them on the Testing Stone may leave Tiny Marks that, even if invisible to the naked eye, may cause a Significant Drop in their value.
