Robust glass machines are used to create robust glass from red sandstone obtained from the Oo'glog and Sophanem red sandstone mines. Use of the machines requires completion of As a First Resort.
The robust glass machine located just southwest of the mud bath in Oo'glog belongs to a dwarf named Rutmir Arnhold. A second machine in the Ithell Clan district can be used just like the one in Oo'glog, but can also turn crystal-flecked sandstone into crystal glass.
