Hello to all,
Somewhat high on Oxycodone, I have read chapter 1 . The first thing I noticed is that the initial swelling of the gelatin is carried out in a solution of KBr, rather than in distilled water. I never tried this. But, given the fact that, in 2010, the chemistry of gelatin is still not fully defined, I wonder if there could be a difference between swelling the gelatin in water, then adding KBr and doing it the Author's way.. There could be a difference in the way in which the Br is dispersed along the strands of gelatin. This might lead to a difference in rate of emulsification and in ripening.
Pure speculation!

But this is pure speculation on my part.
