Fretz uses seamless extruded tubing made from a malleable brass alloy that contains 70% copper and 30% zinc to make these blanks. The tubing is cut and then the edges are cleaned up on a belt sander, then annealed and then given a basic tumbled finish.

Keep in mind when making convex (domed) forms, the doming will make the diameter of the finished piece smaller. When making concave forms, the size of the finished piece will not be affected.
