The listing, Carbon Block has ended.
This carbon block reflects heat and helps to maintain a clean reduction atmosphere, keeping your pieces cleaner through the soldering process. Metal will not adhere to the carbon, making the removal simple and non-damaging.
Charcoal block made from select, close-grained, knot-free wood.
Sorry, I am not a jeweler, I am just a sales person.
I look at a jewelry tools catalog to decipher the purpose of jewelry tools.
Note: I usually do not answer mgs on weekends, during the week, I do it as soon as I can.
Tks., for Stopping-By.
