Precise temperature regulation of the bluing bath is essential for achieving durable, true-color blue finishes. The Brownells stainless steel bluing thermometer is meticulously sealed for use in caustic bluing baths. Each thermometer undergoes calibration and is rigorously verified for accuracy. Inexpensive, poorly constructed thermometers are a leading cause of bluing failures and we believe that any company selling such products to gunsmiths lacks a comprehensive understanding of the bluing process. The Brownells bluing thermometer features a 6 inches stem, with only 3 inches required to be submerged in the bath, providing a 3 inches safety margin to keep the dial above the salts.
