Welcome to Sigma Surfacing. We develop simple inventions for established technologies.

Our Projects Page introduces you to our most recent inventions.

We seek high quality global development and licensing partners to help move our new technologies through commercial development into worldwide sales and welcome the occasion to personally demonstrate the inventions and explore their potential commercial value to you.

For over forty-five years, Howard Newman – bronze sculptor, silversmith, painter and draftsman – has created fine art. For the past two decades, Howard and Mary Newman have been restoring unusual objects of art made of metal and other materials as Newman’s Ltd. You can see illustrated examples of their many restoration projects here.

The accumulation of Howard’s research in developing novel methods and tools for his work resulted, in 2011, in the creation of Sigma Surfacing, LLC, through which Howard, along with Len Katzman began to develop the experiments into patentable, licensable new products.
