I understand why you can't and wouldn't want to demonstrate this yourself, but would it be possible for you to make production instructions (and also where to buy pure magnetite in the correct form)? I'm very interested in trying but I need to know the exact materials and machinery it would take to achieve the right results. It sounds like something you could make, find it doesnt work, and then be told you didn't do 'xyz' correctly (if that makes sense). So a clear overview/outline would be very useful here.
