"The benefits of this new etching methodology over the traditional acid etch approach are compelling, both in terms of safety and in regard to the quality of the bitten work. In 2003, the safety benefits of Metal Salt Etching were scientifically validated by the RIT chemists Dr Paul Craig and Dr Paul Rosenberg (CLICK FOR ARTICLE) in the context of my contribution to Keith Howard's book The Contemporary Printmaker. Key researchers, safety experts and scientists also endorse the use of metal salts for etching. There are several variants of processes, but all are essentially electro-chemical in nature and share many of their basic chemical properties. Metal Salt Etching is becoming accepted as the generic name of salt based etching. I am especially indebted to the essential work of Keith Howard, Nik Semenoff, and Cedric Green that made my own etching developments possible. This web site will be updated regularly to give visitors the latest developments and information on Metal Salt Etching."

Why am I doing this? Surely it is your research project and you should be making your ideas and discoveries visible? You NEED to move this project along ... you need to show a body of research and thinking at the end of the semester ... use the blog to document EVERY aspect of your project
