http://lesjorgensen.com/other-good-bits/lithopanes This is an overview of creating a Lithophane from a common PVC 6 in pipe using high-resolution digital (infrared) cameras, software to port a bitmap image to CNC router software, and the finished product off of a Thermwood CNC router. http://lesjorgensen.com/other-good-bits/lithopanes First mentioned circa 1825, this process involved carving a picture out of wax, then, using a lost-wax casting process, the picture was finally cast in porcelain. Light then transmitted through the reverse bass-relief porcelain was seen as a picture. Dramatic and popular for its time. We have been working with this old process in new ways: using digital photographs and computer numerical controlled (CNC) machine routers that carve relief into Coiran-like materials and PVC. Adapting the photographic process as well as the software for the routers, we have been able to achieve dramatic results. http://lesjorgensen.com/other-good-bits/lithopanes http://classiccustomwood.com/?page_id=642
