purchasing test acid for 9kt Gold in the US

Post by sheely213 » March 17th, 2019, 11:13 am

kt I do a lot with vintage and antique jewelry and cannot find a source for the 9kt test acid. The only sources I have found are in the UK and they cannot ship to the US. I am not as sophisticated as many of your users. Wondering if anyone can offer some help?
