<p>Rust resistant, scratch resistant coatings are formed on glass containers during passage thereof through a tunnel at 500-720.degree.C by forming a first fluid stream by passing dry air through a bath of tin tetrachloride, forming a second fluid stream by passing dry air through a bath of phosphorous trichloride or phosphorous oxychloride, combining the two fluid streams to form a fluid coating stream, and introducing the fluid coating stream containing tin tetrachloride and phosphorous halide in a weight ratio of between 2:1 to 9:1 into the tunnel to contact the hot glass containers and form a coating on the glass containers.</p> |
