Class Codes & Rates:

Code 4131 is applied to insureds engaged in the manufacture of mirrors that range from pocket-size to wall panels of varied types. Glass, plating solutions, polishing, cleaning and protective materials and frames, backs, handles and other accessories are received from others. Mirrors are generally produced by the chemical deposition of metal on glass. For commercial and many scientific purposes, silver is the metal most commonly used. The glass is cut to size, ground, smoothed and in some cases edges may be beveled. Hole drilling, chemical etching, drying, buffing and polishing are also performed. Reflecting surfaces are generally produced by pouring or spraying the appropriate metallic solution over the prepared glass. Heavier coats are obtained by successive applications of the plating solution. For the production of mirrors for scientific instruments, the vapor process is used.
