Numbers 16:36-40 - The Fire Pans
36 Then the LORD instructed Moses, 37 "Tell Aaron's son Eleazar the priest to take out the censers out of the flames and scatter the coals far away, since they are holy. 38 As for the censers of those rebels who died, fasten them into beaten plates to line the altar. Since they brought them into the LORD's presence, they're holy. They are to become a reminder to the Israelis."
39 So Eleazar the priest took the bronze censers that had been burned and beat them into metal plates for the altar, 40 to serve as a memorial to the Israelis, a reminder that no unauthorized person, who isn't a descendant of Aaron, is to attempt to burn incense in the LORD'S presence, so that he may not become like Korah and his group, just as the LORD had spoken by the authority of Moses.
