Ceramic refractory logs are different from ceramic fiber logs because the material they are made from is similar to reinforced cement. Ceramic refractory logs are made through a process of pouring powdered ceramic material and cement into a mold and letting it dry before coating it with heat-resistant paint.
While all gas logs are made to withstand high heat, ceramic refractory gas logs are much more durable than ceramic fiber. Because of the higher quality of the material in ceramic refractory logs, they do tend to be more expensive. Though, when you invest in the more expensive gas log set, you will find they can last 10 - 15 years before the paint begins to fade & show signs of use. A ceramic fiber gas log set usually shows signs of wear around the 8-year mark.
Another benefit of ceramic refractory gas logs is that they aren't as porous as ceramic fiber logs. Ceramic fiber gas logs can absorb odors in the air and put off the smell of your favorite dinner days after you ate it. Though ceramic refractory gas logs don't absorb odors as easily, they can still attract animal hair and dust.
