Hi there,

I have a small casting project I am doing for a friend. I am going to use the lost wax technique. I have done this years ago and my memory is a little fuzzy. Perhaps someone can enlighten me.

I am going to make a crucible out of iron pipe by welding a bottom on it and making a lid and tools to lift and handle it for the pour.

I can't remember if I need flux to clean the aluminum before the pour. I know I will need a ladle to clear off any slag that floats, but what about flux? And if I need it what should I use for flux?

Of course I am going to preheat the mold as hot as I can make it, about 500 degrees in the oven. I think this should work.

Any help will be greatly appreciated.
