Using wax resist.
Just fired a kiln load yesterday and no fumes - no kiln smell. Guess those new vent tubes I installed really made a difference!
I saw a thread about someone using this product: https://www.mcmaster...3145k67/=16d6at
Anyone have experience with this product? The metal ones from the hardware store only lasted a year, and obviously needed to be changed sooner than I did. So, perhaps I should change them every 6 months if I go with those.
