b'HOT SURFACEMARKERSThe tools required in a smelter or forge and casting foundries must be able to consistently perform and be able to withstand extreme temperatures, and industrial markers are no exception. Our hot surface line of solid paint markers will only begin producing marks when in the stated working temperature, and will provide long-lasting, highly-visible marks that will not run, char, flow, discolor, peel, or crack. With rated temperatures from 120F (49C) to 2200F (1204C), these markers are ideal for use on coils, billets, bars, ingots, and plates.'
