Abstract: A method for producing a coated glass or ceramic article having a surface formed primarily from silicates, comprising the steps of contacting the uncoated glass or ceramic article in a gaseous atmosphere at a pressure of at least 700 Tort with a silane and a carbon source for a sufficient time at a temperature of less than 35.degree. C. to form a coating on and in the glass surface, wherein the coating comprises a silicon-carbide-containing layer having a thickness of at least 100 angstroms and containing 35 to 55 atom % carbon, between 15 and 30% silicon, no more than 10% elements other than silicon, oxygen, and carbon, and the remainder oxygen. Glass and ceramic surfaces having the indicated compositions are also part of the invention.
