If you are willing to test samples, it might be wothwhile to test one of my emulsions. I think that everyone on this forum makes gelatin based emulsions. I am an an Old Hippy and make emulsions based on modified PVA. The rheology is very different. I will send you some. Just tell me where to send it.
I assume you are equiped for protecting your liquids and spun plates drom light? To keep it simple, I can send you a sample sensitive to only blue light.
How large a sample do you need ?
