1844 R. Hunt in Athenæum 1 June 501/1 The exceeding sensibility of the Energiatype is best shown by an attempt to copy engravings or leaves by it.
1859 Encycl. Brit. XVII. 550/2 Under the name of the energiatype, Mr. Hunt published an account of a process in which the salts of iron were used; but he afterwards adopted the more appropriate name of ferrotype.
1918 Photo-miniature Mar. 2 No attempt has been made to give the names of the countless processes introduced in days long past and now obsolete, such as Energiatype, Chrystolotype, Hillotype, [etc.].
2000 R. Hirsch Seizing Light iv. 77/1 The name ferrotype..was originally used by Robert Hunt in the mid-1840s for a paper negative process (Energiatype) that utilized an iron-compound developer.
