[alt-photo] Re: Dichromated Gelatin Formula

[Kurt Nagy]

I have used a 3.5% gelatin mix (7g or one packet of Knox in 200ml water).  Following that, to get 20% in 200ml you would need 40g of gelatin.

Someone may check my math because I'm horrible at it but it seems right to me, if I'm understanding your question right.
