A detailed account is given of the uses and limitations of glass linings and porcelain (vitreous) enamels for metal structures. The discussion of glass linings goes into such matters as nominal composition of glass, production and preparation procedures, application, metal surface preparation, firing atmosphere, equipment design, hydrogen spalling, thermal shock, etching, abrasion resistance, testing techniques, heat transfer characteristics and repair of glassed steel equipment. Test data reported include the resistance of borosilicate glass to five acids (hydrochloric, nitric, sulfuric, acetic and phosphoric) and to three alkalies (sodium hydroxide, sodium phosphate and sodium carbonate).
Topics discussed in connection with the use of porcelain enamel coatings include production procedures, application, nature of metal substrate, thermal shock, and possible industrial uses. 5.4.2
