proper temp for iron sulphide production?

[Glacial_Refluxer]

When fuseing iron and sulphur together what temp is
required? Can this be done in lab glass?

[calcium]

Fusing iron with anything would require a crucible, not lab glass. Porcelain or graphite?

The reaction of iron and sulfur gives off alot of heat, if your useing finely divied iron such as steel wool, once its going it should keep going.  Try it on a really small scale to get a feel for the rxn.
