Dichromate sensitizer Help / Challange!?

Hello Fellow TLovers,

Does anybody have info on using dichromate (crystal form) as a sensitizer - not diazo. I know dichromate is no longer used due to its toxic nature but where i am from i have no option.

It would help if somebody had some kinda formula as to how much of dichromate should i add to X amount of emulsion. And also the kind of exposure would best suit the stencil.

Thanks a lot guys but so far i haven't found any help with using dichromate, not many are familiar with it - it seems.

Thanks Again - Peace
