Measuring Temperatures in Furnaces with Oxidizing Atmospheres

Sep 03, 2018· A kiln is a particular type of furnace used in ceramics. At high temperatures many materials start to react with the surrounding atmosphere. If that atmosphere is very short of oxygen, it may pull oxygen from the material being heated. Such an atmosphere is termed "reducing". Gas heating usually results in an oxygen-deficient atmosphere.
