BTW Daniel I forgot to mention, Bergger is also making contact printing paper. If you try it let us know what you think (I wish william would hurry up and give us his opinion). Another alternative is using printing out paper made by Kentmere Ltd. and sold by the Chicago Albumen works

Although they had some problems with coating they have been resolved and are now in full production. This is a wondeful paper and the range of tones and colors that can be acheived with this paper is far beyond anything you can get with Azo. This is my choice of papers when I wish to contact print in silver.
