We make our soap in small batches, measuring out the vegetable oils, water and Sodium Hydroxide (NaOH). We mix the oils and water/NaOH solution when everything is about 90 degrees F. Once the mixture has started tracing, the solution starts to look like pudding, we pour it into our handmade wooden molds. The molds are wrapped to insulate them. The soap continues to saponify in the molds. Saponification is the chemical reaction that converts the oils and alkali into a sodium salt, which is what we all call soap. 2-3 days later the soap is removed from the molds, cut into bars and then placed on racks for 6-8 weeks for curing. Curing lets moisture out of the bars, increasing their hardness. Throughout the process we measure the PH of the saponifying solution and bars as well as checking for water content and hardness. A saponified bar has no Sodium Hydroxide let. All of it has been used to make soap. Once cured, the bars are hand wrapped and shipped to our customers. That makes a batch of cold processed soap, from our hands to yours!
