Numbers 17:2-5 describes the covering that was made for the altar from the fire-pans of Korach's rebels:
[...] 4 And Eleazar the priest took the brazen fire-pans, which they that were burnt had offered; and they beat them out for a covering of the altar, 5 to be a memorial unto the children of Israel, to the end that no common man, that is not of the seed of Aaron, draw near to burn incense before the LORD; that he fare not as Korah, and as his company; as the LORD spoke unto him by the hand of Moses.
From v.5 it sounds like this was a covering for the incense altar, not the bigger one. From v.4 (and earlier) it sounds like the fire-pans were beaten flat and joined together somehow.
Was this formed into one big sheet or was it individual plates joined (hinged? linked?) together?
Did this cover stay in place while incense was being offered, or was it just a cover during "off" times and it was removed when the altar was to be used?
Was it used only in the Tabernacle or was it brought into Israel and used in the Temples as well?
Can 250 fire-pans be turned into a cover of that size? (How big is a fire-pan, anyway?)
(This question arose out of today's parsha chat.)
