Hello! I am new to firing at home and I have an old Duncan kiln in my basement. I have it in my laundry room on a stand and I have been leaving the window open and closing the door to the room when I fire but I can still smell it upstairs sometimes. I have been trying to read up on kiln venting and I'm wondering if this is something I 100% need to do? I'm only doing low fire up to cone 04, does this make a difference?
