Ceramic Glass Vs Tempered Glass When you are looking for fireplace doors, it is important to know what kind of glass will work best for both you and your fireplace. Whether you have ceramic or tempered glass fireplace doors, both will increase the efficiency of your fireplace. However, there is a big difference between having ceramic and tempered glass. Ceramic glass has a higher thermal shock rating than tempered glass, at approximately 1400F. The thermal shock rating is the temperature at which cracking will occur from the result of rapid temperature change. An easy tip to keep your home cozy this winter is to keep your glass doors closed. This will keep your fire from sucking all of the warm air out of your home. ONLY DO THIS WITH CERAMIC GLASS. Ceramic glass can handle higher temperatures than tempered glass. Ceramic glass allows more heat to radiate from the fire and into your home. Also, it visibly differs from tempered glass - it has a slight amber tint to it. Besides being a great option for your fireplace doors, ceramic glass is also suitable for use in cast iron stoves. Fireplace doors normally come standard with tempered glass. Tempered glass is also called safety glass because it shatters into many small cube shaped pieces. Tempered glass is quite strong; however, it has a lower thermal shock rating at approximately 600F. Do not keep your fireplace doors closed if you have tempered glass. With its low thermal shock rating and higher temperature, they are more likely to crack.
