A studio space was set up at the empty Germania hall an old dance hall in Indianapolis here Benton set to work with his sketches Thomas Hart Benton Art a shelf of history books an ample amount of supplies and a crew of assistants this is where the artist would take his sketches and increase their scale to larger cartoons that were lined in a grid pattern.
The full-scale canvass was prepared in the same way then he sketched in the elements in the scene filling the great map of mural sections that he had created it’s at this point the native Hoosier hens began a daily contribution to the work the hens provided the most important element in Benton’s tempera painting technique eggs pens egg tempera technique was somewhat of his own invention.
I would say he started his revival of egg tempera painting in the mid s using translated texts from the century Italian painters and I’ve read these texts myself and they’re often the language is different the measurements are different and many times.
You have to kind of speculate what they really were referring to in the #wikiart text I think he came up with using basically the simplest of these techniques we found a lot of conflicting documentation about what kind of paint meet have been actually used on the murals it seemed unlikely to us.
When we came across a report that said that he had painted the murals in egg white and water which would sort of really be unexpected we had done several campaigns of analysis on the murals the chemical analysis actually supports more that he used egg white rather than egg yolk in his paint in his paint medium well we can we can only speculate why Benton used this particular technique my feeling is is that Benton was fairly nonchalant about his paint mixing techniques
