What is the percentage of lead use in your metal jewelry findings ?
Guyot Brothers uses 85/15 rich low brass in the production of all its decorative stampings and jewelry findings. This materials nominal composition is 85 % copper, 15 % zinc however each batch of material is slightly different and it is not unusual to have what is commonly referred to as "trace amounts" of lead and/or nickel. This link leads to the Olin Brass MSDS sheets and this link leads to a typical Certificate of Compliance for a more detailed reference.
