Right. One of my two aluminium-foil trays has sprung a leak, and 
the sauce from a rather large shepherd's pie is coating the floor 
of the oven with syrup. We'll get to "cleaning your own oven" 
next week. 
In the meantime I seem to have lucked into a soil sterilising 
tray for free. The pinhole won't matter to me when I pop a few 
trowel-fulls of composted soil into the tray to bake it to kill 
off weed seeds (aka pumpkin seeds and the like, that the worms 
didn't eat). Question is:
        1) how high a temperature and
        2) how long.
I'm guessing that the boiling point of water 100C or 212F will 
kill off most seeds. I'm also guessing that if leave it in too 
long I'll end up with a tray of chemical ash, with little 
humustic (?) value.
Any takers? bakers?
