I recall a posting about sulfur and gold sensitation that PE said should be around 3:1.

On the light farm website they use Steigmann standard aurous ammonium thiocyanate solution (50ml ammonium thyocyanate 1% and 6ml gold chloride solution 1%) which is about 8:1. Is this "strong enough" or a comprimise because of increased fog with increased gold?

It's in the section on glass plate emulsions.

Thanks all
