Sam founded Protostamps after realizing that stamps made for glass art needed to have the material and application considered in the creation of the stamp itself. Understanding the nature of glass as a material enables Sam to identify the strengths and weaknesses of protruded, or extruded stamps. This informs whether any stamp design will register well onto the glass when applied. The transparency of the material alone allows for the viewer to see through the glass and onto the surface itself. Through conversation about the type of glass and use of the stamps, Protostamps designs are always made to fit your needs.
