Homemade solid cream, I use half a catty of Colla Corii Asini, half a catty of antler gelatin, half a catty of tortoise shell gelatin, the three gums add up to a catty and a half, how much yellow wine to put? 1, about the amount of yellow wine should be added and the total of the three gum equivalent, that is, one and a half pounds.

2, on the three gums into powder after in the end to soak in yellow wine for two days, the answer is not necessary. Before I saw the example of soaking with yellow wine to deal with gum and other gums because in ancient times there is no powdering machine, or in the absence of conditions for powdering the use of yellow wine soaking can make the gum into the yellow wine, to facilitate further melting, since you have already been powdered there is no need to soak in yellow wine for two days.

I don't know if the owner is satisfied with this answer.
