This is not, however, to be regarded as the invention of lead glazing, since, as William Burton writes (“Ceramics” in EB, p. 706), “lead glazes were extensively used in Egypt and the nearer East in Ptolemaic times.” He adds, “And it is significant that, though the Romans made singularly little use of glazes of any kind, the pottery that succeeded theirs, either in western Europe or in the Byzantine Empire, was generally covered with glazes rich in lead.”
[3031] For these works see Berthelot (1893), III, or Lippmann (1919), who follows him. I have not had access to E. Wiedemann, Zur Chemie bei den Arabern, in Sitzungsberichte der physikalisch-medizinischen Societät in Erlangen, XLIII (1911); and his Die Alchemie bei den Arabern, in Journal für praktische Chemie, LXXVI (1907), 85-87, 105-23.
[3032] The full title is “Compositiones ad tingenda musiva, pelles et alia, ad deaurandum ferrum, ad mineralia, ad chrysographiam, ad glutina quaedam conficienda, aliaque artium documenta.” The MS, Bibliotheca capituli canonicorum Lucensium, Arm. I, Cod. L, was printed in Muratori, Antiquitates Italicae, II (1739), 364-87. It is described by Berthelot (1893), I, 7-22, whose comparison of it with previous treatises I follow.
