Forget the expensive kits that have multiple different vials of acid - get only the 18kt gold testing bottle and you are set to test for both gold from 14k up to 24k or silver from 675 up to 999!
How does it work?
Gold:
For 14k gold the 18k acid will eat away the gold in about 8,9-10 seconds, any other base metals will dissolve almost instantly, the 18k gold will stay and not disappear
Silver:
The magic here is great! All silver purity from about 600 on up will turn a chalky white and not dissolve with this acid and as time progresses and you do more tests - by the whiteness of the chalk left over you will be able to tell the difference s in the metals purity.
The ring in the photo had a little of both 18k gold and 950 silver.
Have fun! Cheap!
Nice post. I am been looking for that kind of products. Which kind of vendor do you use?
I went on ebay and purchased the cheapest 18k acid I could find, Back then it was $5 with shipping i believe and so far its been lasting me about 4 years.
OK. Thanks! Have some unstamped silver I need to test for purity.
VEry cool. This would come in very handy.
If you get a good enough sturdy bottle you can even have a flea-market kit, though I have run into some persons that really don't like someone testing their 'word'
Thank you for your continued support of SteemSilverGold
