Query: Good "Keep Warm" Trivet for a Wood Stove

Including the three tabs that stick out (about 1/4"), the trivet is ~8-3/8" diameter (it would not fit in a pot with an inside diameter smaller than this). The three supports are ~3/8" diameter bosses that hold the trivet ~1/8" above the stove top (or pot bottom). The trivet is made of ~1/8" thick cast iron, so its total height is ~1/4".We bought two of these to use on our wood cook stove. When the stove is very hot, placing a pot on top of one of these helps keep the food from burning. This design has very little contact with the stove though, so--unlike a little "cereal" trivet rescued from an old McClary Charm wood stove--we can't use it to make cereal over a typical fire (does not let enough heat get to it). For this use, a little more stove contact would be nice. You need a really hot fire to actually cook on this. That said, this is very effective for keeping things warm on the stove without burning them.
