I got a new batch of 100 sheets of Rives BFK from my favorite supplier, Bostick & Sullivan, today. I’ll be having a sizing marathon this weekend getting all that paper ready for gum printing. I’ve not tried a lot of other papers yet, to keep the variables down, but I’ve been quite happy with the Rives BFK so far. It’s a 90# watercolor paper with good wet strength, and I’ve been able to coat up to five layers so far without having to re-size. After I get through this lot, I’ll have to try the Lana Aquarelle I have sitting around. I’m also going to try using an alum-based hardener in the sizing instead of glyoxal because it’s not exactly practical to try and size paper outdoors in this weather, and my basement darkroom doesn’t have good ventilation.
