Hello everyone, I have a wood stove that I've been using for 12 years. I noticed at the end of last winter, The mortar type liner inside the firebox is coming up. I got a few chunks of it when I was cleaning out the ashes. Can someone tell me what this liner is made of. I need to replace it before winter gets here. I looked at it today and I can take my ash shovel and lift most of it up. This is the mortar that is in the bottom of the firebox. Someone told me they had firebrick in theirs, but this is not a brick, it's more of a mortar
