The heat blued finish put on some steel parts by clock and watchmakers is quite dependent on a consistent, even heat being applied to the part. Smaller parts like short screws can be heated on a thick piece of brass with holes drilled to accept the threaded portion of the screw.
Larger parts are best heated on a bed of brass chips, held within some sort of tray. For some time I've been using a tray cobbled together from brass scraps, so in this video I make a more permanent version.
