I use a 15 gallon stainless pot. Add water boil, then put the comb or cappings in. The heavy stuff falls to the bottom and honey dirt etc mixes with water. Try to clean cappings throughly with water before going thru heating process. Once everything is melted I run thru a corse strainer. Then thru a finer mesh. Let the block solidy with water. Once cooled overnight, pull out block and scrap the bottom clean of dark slum gum wax. With brood comb I repeat the process twice to get more slum gum and have cleaner lighter wax. Brood comb sucks, its smelly and a pain in the butt dealing with caccoons. With brood comb I think their are better altenatives such as steaming or solar, but havn't tried those. If I had a presto pot I'de porbably only use it for cleaned wax.How do I melt 10 pounds of wax or more at a time , I'm just trying to melt it and get the impurities out , I'm using a presto pot for heating it and pouring but thought I would keep it just for pouring and keep it clean .
