But he insisted that he could not live with the present metalizing.

He developed an improved silvering method, which would become the standard for coating first surface mirrors (known as the "Brashear Process") until vacuum metalizing began replacing it in 1932.

Vacuum metallizing was used to deposit aluminum on the large glass mirrors of reflecting telescopes, such as with the Hale telescope.

Vacuum metallizing is a process where a metallic coating material is placed in a vacuum chamber with the workpiece to be coated.

Vacuum metallizing involves heating the coating metal to its boiling point in a vacuum chamber, then letting condensation deposit the metal on the substrate's surface.

He is the engineering and systems manager of Providence Metallizing Inc., in Pawtucket, R.I., a company that applies finishes to metals and plastics.
