please. quick help re: potassium oxalate. VD and kallitype printing

hi all,
i am trying to order chemicals for my van dyke and kallitype printing. i am new and trying to get it right......do i need potassium oxalate for clearing or can i use regular stop bath?

please let me know if i am getting what i need or if i am buying something that i do not need.
i guess i will wait to see what you all think. here is my list so far for van dyke and kallitype printing

silver nitrate

ferric oxalate

rochelle salts

borax

sodium sulfite

sodium thiosulfate

tartaric acid

ferric ammonium citrate

sodium citrate

sodium carbonate

potassium oxalate

and maybe oxalic acid and potassium ferricyanide if i need them.

all comments are welcomed. i am just trying to place one order. i was going to do it tonight....but i guess it can wait one or two more days.

thanks

eddie

ps.

is the ferric oxalate from artcraft chemicals the one i want (ie trihydrogen ferric oxalate [H3Fe(C204)3])

I order all of my ferric oxalate from B&S because of its purity so I can not answer about the chemical from artcraft.

You do not need potassium oxalate for clearing, but as a developer. The two primary developers I use are ammonium citrate and potassium oxalate. For clearing I use a combination of sodium sulfite and EDTA.

I do not like Rochelle salts because like many workers, I have difficulty with the longevity of the print when this developer is used. Apparently you have garnered much of your information from the book "Making Kallitypes", by Stevens.

If this is true, I suggest you do a search on this forum and on Unblinking Eye for better info on printing kallitypes. Much of what is in Stevens book is refuted by workers in the field. Some of the more up to date methods will yield more permanent prints, with fewer chemicals and problems.

i will continue to do research. i am asking because tyhe research i have done so far is very confusing! according to the potographys formulary the potassium oxalate is for clearing....(page 4).

i am not trying to do Platinum Palladium printing

thanks
