I had been asked that is there a alternative to silver at emulsion making and is there a research continiue or discarded at Kodak. Answer came from Photo Engineer and he indicates copper but details lost.

I am finding great oppurtinities at widely manufactured metal powders. First is titanium dioxide , it is used at sunscreens , solar cells , paintings , food industry.

I suspect , there might be use in emulsion making also. Its cheaper than steel 3 times and 25 kilograms comes for 30 dollars or less. There is a great use at visible , uv light technology.

If there is a idea sparks in your minds or if you know a technology new , please share and lets open a way rescue from spending thousand dollar to kilograms of silver.

Thank you ,
