[Alt-photo] Re: Was Sulfamic now VDB and pt/pd gold leaf

[Don]

Thanks Sandy. 

I would encourage anyone interested in the Agyrotype process to purchase the
silver oxide or purchase a kit from the usual sources. 

If one decides that they indeed like the process then the effort required
making silver oxide from silver nitrate will be worth while. For the
neophyte it may prove to be off putting and create a built in receipt for
failure.

Don,

Both Sam and I were able to get very high shadow density (Dmax of about log
1.6) using acidified Lanaquarelle with both gold-tone vandyke and
argyrotype. Not sure how Sam acidified the paper, but I used a 1.5% solution
of oxalic acid, soaking the paper for five minutes. Lanaquarelle is a
wonderful paper for this process.

Would add that this work was done in late spring, early summer when RH in
our work spaces would have typically been around 50%-60%.

Sandy
