20 VITREOUS ENAMELING 



Springer, L. What precautions should be taken in replacing soda or potash 



(in glasses and enamels). Sprechsaal 52, 362-3 (1919); C. A. t 14, 809; 



J. Soc. Chem. Ind., 38, 902A. 

 Treischel, Chester. The cause and control of blistering in sheet-steel enamels. 



/. Am. Ceram. Soc., 2, 774-81 (1919); C. A., 14, 107. Experiments show 



that hydrogen has much to do with this. 

 Vielhaber, L. Fuel consumption of muffle kilns in the enameling industry. 



Keram. Rundschau, 27, 293-4 (1919); C. A., 14, 811; /. Am. Ceram. Soc., 



3, 83-5 (1920) ; J. Soc. Chem. Ind., 38, 862A.

Landrum, Robert D., and Frost, Leon J. Titanium enamels. /. Am. 

 Ceram. Soc., 3, 316-21 (1920); C. A., 14, 2688. The good qualities 

 resulting from the use of titanium seem to more than offset the bad 

 ones and it seems possible to overcome some of the difficulties and de- 

 velop enamels of very substantial practical value. 



Lindemann, W. C. The electric cleaning of metals for enameling purposes. 

 J. Am. Ceram. Soc., 3, 252-5 (1920). The electric cleaning process is 

 superior to the older scaling or burning off method. 



Metallic coating for the rust proofing of iron and steel. Bureau of Stand- 

 ards, Circ. No. 80; /. Am. Ceram. Soc., 2, 844. 



Shaw, J. B. Fish scaling. J. Am. Ceram. Soc., 3, 489-97 (1920); C. A., 

 14, 2689. Chemical composition has very little bearing on the subject 

 of fish scaling. It is probably due to a number of contributory causes, 

 which are discussed.
