I drilled a 1.25" hole in some wood, and slotted thought some 1/4" x 1" A36 steel. There's 1/2" of space below. I then filled this up with thermite, around 50g.
Magnesium fuse worked better this time. I sanded it down to remove surface oxide which is supposed to help.
(Auto darkening welding mask is very helpful here)
Glowed for a few minutes after.
The bar came out with zero evidence of melting.
Now for the microscope.....
