Hi, I’ve taught soapmaking almost 30 years. The classes last 3 hours and the students take home a 2 pound batch in a deep dish plastic food container. They get a 20 page booklet that I update often and print out at Office Depot a few days before the class.
Students measure out their fats at work stations and melt in a small microwave but I provide a pre mixed 1:2 lye solution. I do demonstrate making a small lye solution so they can see how to do it and see how hot the solution gets.
I was lucky to have Rustic Escentuals sponsor my classes, providing venue, scents, and colorants. Since they were bought out and moved, the new folks aren’t interested.
This is basically the outline of the class.
A little soap chemistry and safety
A little soap math and intro to soapcalc
Describing what they are about to do using booklet
Showing what they are about to do, modeling proper procedures
Letting them get up and do it while I and a helper supervise and assist.
Everybody takes home their beach towel wrapped container of saponifying soap batter to cut into bars the next day. They also get a few bars of my soap to use while theirs cures. Then they get in a Fb group I make for the class to discuss the results and share pics.
I charge enough to cover my expenses and clear $100 for each student. I will cancel a class if I don’t get a minimum number of sign ups and deposits by the deadline.
A demonstration is a different story. I’ll demonstrate making a 2 pound batch for any number of people, give them one recipe, and a small hotel sized bar of unscented soap.
I hope this helps you decide how you want proceed.
