The sizing in both of these papers is, as mentioned, a chemical problem for siderotypes of any sort.

I've printed cyanotypes, salt prints, and kallitypes on both papers with great success after switching from oxalic to sulfamic acid pre-treatment of the paper to neutralize the sizing.

(Does that answer your question? If not, elaborate and I'll try again!)
