			* Used steel wool as soruce of Fe, hoping for fast dissolving in Al. Does not work well.
			** Too large volume, makes packing into crucible difficult
			** Starts burning after while being added to liquid Al
			** Tried wrapping in alu foil, in tight packets. Sort of ok, but very, slow to dissolve, borax get in everywhere , mess.
			** Next time either skip Fe, or try shavings from a file of drilling swarf.
			** With filings, iron will still take a long time to dissolve in Al
			* Current crucible handlling tools are inadequate for the oven.
			** All tools must be long enough to never have to reach into the oven, and preferably stick out at least 30 cm from the edge
			** Crucible lifting tongs, that are lockable
			** Long, fine stainless steel tongs for adding metal
			** 2 x Long stainless stirrer / prodder
			** Stainless spoon, with long handle
			** Pouring rings should be custom made for each crucible type, to ensure maximum stability. Make sure handles are easy to pick up then ring lays flat on the table or floor.

			** Set up crucible so that maximum of operations can be done without opening the door
