[alt-photo] Re: a new old process

[Alberto Novo]

Just for sharing what I have found:
the name of the method is pannotype (almost equal to the Italian pannotipo), 
and there are some information and even pictures in Internet:
1853 published by the company Wulff + Co.
only used until 1859/60 since the material is very unstable (photographic 
layer easily gets cracked). *displaced by the ferrotype process.
general process: collodion negative on blackened waxed cloth to which the 
photographic emulsion is transferred after it got developed, separation of 
the collodion in a bath of sulfuric acid (1:20)
