Hi, I'm going to put a firebasket in my fireplace and have a few questions... 1. the inside of the fireplace is currently rendered. Although we won't be using the fire very often, am I right in thinking that the inside of the fireplace will go black after a while? In which case, I'm thinking that we need some tiles or something on the render (I presume you can clean the black off tiles but not from render?) 2. Can you use any heatproof tiles inside the fireplace (assuming such a thing exists!) 3. Do I need something under the firebasket, as ash would just fall straight onto the hearth. Many thanks indeed!
