Use that cast iron box fer an ashtray. Get yerself a 9x9 cake pan, put yer chips and chunks in there, cover with aluminum foil, poke bout 5 er 6 holes in there, that prevents the flare ups, after your smoke dies down ta near nothin, pull the foil, shake the pan a bit an yall ready ta get more smoke outa them chips an chunks. Better then the original.
