This reaction can be carried out as a demonstration or class experiment in a well ventilated laboratory provided that the instructions provided here are strictly adhered to.
The reaction can be carried out in borosilicate glass test tubes as a demonstration or in smaller (ignition) tubes by students. The reaction provides an opportunity to show that the properties of a compound are different from its constituent elements.
The reaction must not be carried out on tin lids in the open laboratory as is suggested in some sources. The sulfur may boil or burn releasing sulfur dioxide which is a TOXIC and CORROSIVE gas and may trigger an asthmatic attack.
