Practical guides on thermocouple calibration, heater replacement and firing consistency in dental laboratories.
Written for working dental laboratories: how to recognise thermocouple drift before it ruins restorations, when a porcelain furnace heater has reached the end of its life, and which sensor type your porcelain or zirconia sintering furnace actually uses.
Why zirconia sintering furnaces use noble-metal type S sensors while porcelain furnaces use type K — and what that means for accuracy, drift and replacement cost.
Slow heat-up, dull glazes and visible hot spots: how to diagnose a worn porcelain furnace heating element and what a correct replacement must match.
A drifting thermocouple quietly ruins firing results long before it fails completely. Learn the seven symptoms labs report most often and how to verify a sensor.
