Izgubljena formula Janeza Puharja [Elektronski vir]
Govori o slovenskem izumitelju fotografije na steklo z vidika tujega opazovalca, Škota Robina Crichtona, ki se sprašuje, kako in zakaj ga častimo, saj je v zahodnem svetu malodane neznan. Crichton se ...odloči, da bo slovenske trditve raziskal kar sam. Puhar namreč trdi, da je za svetlobno občtljivo tvarino uporabljal živo srebro, žveplo in jod, pa morda še lak, s katerim je na koncu zavaroval emulzijo. A njegova prava formula ni bila nikoli in nikjer obelodanjena.Ves svet pa seveda ve, da še nihče ni uporabil Hg, S in J za izdelavo fotografij, saj niti sami zase, niti v skupnih spojinah ti trije elementi niso svetlobno občutljivi. Zato se Robinu porodi ključno vprašanje: so torej štirje Puharjevi originali, ki trenutno obstajajo na svetu, pravi ali samo zmota slovenskih zgodovinarjev in muzealcev?
