Chemical Tempering Furnace – Multiple Chambers The Lumina M is a high volume multi chamber chemical tempering oven used for mass production of thin glass products requiring zero optical distortion. Chemical tempering ovens use the process of iron exchange. By immersing the glass into a Potassium Nitrate chemical bath the sodium irons close to the glass surface are replaced by larger potassium ion atoms. As a result of this chemical exchange the glass has a stronger surface layer. Products using chemically tempered glasses include mobile phones, digital cameras, copy machines & aircraft windscreens.
