I forgot mention, it is for home tan.
The Formula is: To every 10 gallons of Water, add 5 Lbs. of Salt and 4 Lbs. of Alum. This soluton should test at somewhere around a 2.78 PH - depending on your local water. Soak the skins for 3-5 days. Do not add any Sodium Carbonate to this mixture. Keep it at that low PH.
