The wife's cast iron skillet recommends a heat spreader thingy to
go between the element/glass top and the skillet , and the copper
ones are priced ridiculously . I'm off to scrounge a 1/4" Cu plate
today , but thought "well, I already have some aluminum..." .
So the obvious question is : is this safe ?. I know the element itself
gets hot enough to melt Al , but what about the glass top ?.
Also , does Al put off toxic fumes when it's hot ?. What do the big
giant heads say? ...

Not being from Easter Island, I'll leave the "giant heads" thing lie ..

but most baking pans in existence and also most stovetop pans (ever heard of
Calpholon?) are made of aluminum.
