Morgan Crucible was established in 1856. See http://ubshwiki.ballarat.edu.au/index.php/Morgan_Crucible_Co.

A crucible is used to hold small amounts of chemicals during heating at high temperatures. The lid covers the bowl so nothing escapes, or to keep oxygen out of the reaction. (http://wiki.answers.com/Q/What_is_a_crucible_and_how_is_it_used_in_a_laboratory)
