Failed cast silicon. From the source: This is a mistake from a university research laboratory- someone was trying to melt some high purity silicon into a crucible, probably graphite. The melter they were using employed a vacuum/argon electric arc melting chamber, with a vacuum-suction casting attachment below where a trap door opens below the main melting chamber and your molten material is sucked down into the crucible (hopefully).
