The photo shows a view from above of a Hirsch funnel, which is a large amount of very dark purple, paste-like substance plastered across one side and the bottom of the funnel. The filter flask in which the Hirsch funnel is seated is partially visible below, and its contents appear to be purple as well.

The photo shows a pile of dark purple, almost black paste-like solids on a piece of weighing paper.

The photo shows a laboratory scale, upon which a pile of black solids on a piece of weighing paper are resting. The solids are in several large chunks, but look considerably drier than in other photos on this page. The screen on the scale reads “1.2877 g.”
