today i picked up a drum, it had contained vegetable oil. i gathered up all the goodies i needed and in an hour or two the building process was complete. here is my question. i loaded the basket with briquet's and fired her up. all the vents (1 1/4 close nipples with caps) are full open and she is running over 400 degrees. i can easily see this thing going till sun up tomorrow. should it be safe to cook in after that?
