 Melting the Iron Crucible
+Approximately 1.9 grams of iron works well (seven pellets).
+The pellets need to be melted into one big blob. The photo shows a good iron melt.
+{{::iron_melt.jpeg?400|}}
+  *Give yourself 30 minutes for this task.
+  *Be patient during the melting, it takes time for the heat to spread from the hot spot.
+  *Let all the iron reach the same temperature, then decide if you need more electron current.
+  *If the electron current is too high, you might see glowing sparks ejected from the melt. Like the sparks that shoot out of a camp fire.
+  *As melting proceeds, the metal puddle will have better thermal contact to the crucible. Therefore, heat will dissipate faster and more electron current might be needed.
