Yes, creams load differently than soaps. With Castle Forbes cream I just get a little bit on the tip of the brush and give it about five seconds of of swirling in the bowl then proceed to face lather. A dollop somewhere around between a peanut and an almond should be adequate. With hard soaps like Tabac or D. R Harris I load the brush up to 30 seconds before I start to face lather.
Some creams come in glass jars like Penhaligon's Blenheim Bouquet. Baume.be might come in a glass jar, I think. I understand not liking plastic tubs but one of the best creams, Castle Forbes, comes in plastic tub.
