Roseco Inc. / Dallas, 972-991-9731, 800-874-9436 www.roseco.com is my source for Kerr Labs investment, wax, and other casting supplies for lost wax work. They are listed on the Kerr Labs site They are wholesale only and have reasonable rules to avoid the hassles of retail operations. I walk in to pickup my supplies to save shipping on the fairly heavy investment. The catalog can be requested on line and has a huge selection of tools, equipment, supplies, and books as well as jewelry findings and raw precious metals if that interests you. 2006-08-23
