How much liquid glycerin should I add to a puck of VDH deluxe to make it even more lubricative? In US measurements.
I've never added glycerin to any of my lather personally, but from what I gather it's only a drop or 2.
I would add clay instead of more glycerin.A soap maker would tell you how much you have to add,but I believe that with a spoon would be more than enough.
I use to add it to my underperformers and I would add 6-8 drops in the bowl. I wouldnt worry about skimping b/c it doesnt seem to impede the lathering ability and will rinse off after the shave.
