for some things, thin paper seems best

its been a week or two since i mixed up the emulsion,and started playing with it.  i’ve come to the conclusion that this emulsion works likes thin smooth paper like the butcher paper that i use thick velum paper i sometimes use for bottled emulsion paper negatives and cyanotypes don’t really provide a good negative for me with this emulsion, maybe it is because i don’t use photo grade gelatin, maybe its because i didn’t coat the paper with gelatin first like a sub layer so the emulsion sits too far in the paper, i’m not sure what it is, but the next coating sesison i do, i will coat more thin paper.  i do have some thicker sheets coated, i actually double coated everything to give me better contrast.  i get OK contrast but some of the images just don’t work well.  i have some that worked well, but my success rate is not very high with thick paper.

ive been doing small test sheets, in a 35mm camera to get an idea of iso, and how the images look.  the emulsion is starting to get white and black speckles in it  so i have to use it up before it goes bad, and then i will probably use up my bottled stash and make some more fresh emulsion soon after.
