yeah here is the the quote from the post:
"I hope all you Lang smokers are having a nice Thanksgiving!! My birds on the smoker and cooking.
To recap, I added thin UNGLAZED porcelain tiles to my fire box and covered them with shinney side up alum foil and then took readings with my heat gun. The Lang gauge registerd 300F and the chimney gauge read 295F. The front of the fire box read 536F, the back read 483F, the top read 568F and the door read 399F
A couple of weeks ago the bottom, with only alum foil, read 313F. Today, with the combination of the tiles and the alum foil, the bottom read 125f!! Obviously, I'm not losing much heat through the bottom as most of it's going where it's suppose to go -- into the cook chamber. The mate that added the fire bricks had a good idea.
with just the bottom got the temp down to 125 that is a lot more heat going to meat I am thinking about doing the bottom and the sides with the Grill Greats being only 1/4 in I will not loose much space just need to figure out how to put them on the sides.
