Building a carbide furnes.
for this project you will need
chipped lime
crushed charcoal
a carbon rod
a welder
when makeing carbide you dont want to use powdered lime as it will blow out of the furnes, you need some thing thats denser. your charcoal also should not be too fine or it will be blown out too.
you will also need a steel crucible to melt the lime in. I have noticed that if a cast iron pot is used, it can crack and if that happened with a full pot full of molten carbide.... I think you should get the point. the size of your carbon rod should be a certain size so that it will work correctly (i'll talk aabit more about this later when it comes to runnig your furnes, just remmber the size of the rod determines the size of the furnes. AMPS to size of rod.)
I haven't finished this project but, i am working on it! if it interested you iam sorry its not finished yet. if you would like to know more just ask away iin the comment section below.

A man named James Turner Morehead from Spray, North Carolina invented the carbide furnace around the turn of the century and patented the idea. Lucky for him he did because he founded Union Carbide, the largest producer of calcium carbide in the world.
I've attached the drawing from Morehead's carbide furnace patent.
My book, The Flight of the Hog Wild, is partially about prisoners of war during WWII in northern Korea who were forced by the Japanese to manufacture calcium carbide using a Union Carbide-type electric arc furnace. I bet the Japanese bought the rights from Union Carbide before the war.
