Grain growth restrainer

Post by jeand »

Hello everybody,I've made some silver halide plates based on the diffusion method
described by Jeff BlythWorks very well!
But now I want to try to mix AgNO3 + LiBr directly in the gelatin.
But in this case, I must use some grain growth restraining agents because AgBr grains have the bad tendancy to agglomerate and then increase grain size.Does anyone who knows what I can use as grain growth restrainer ?
In some publications, I found that PVA (Polyvinyl Alcohol) can be used but what else ?Thanks in advance.Jean
