The quantity of heat acquired or lost by a system is given by:
M*S*?T
Where:  M= mass
	S= Specific heat
 ?T= change in temperature

So if the mass of the wood and metal are the same; and the change in
temperature are the same (Taken out of the oven together at the same
temperature), then the only thing left is the specific heat. The item
with the greatest specific heat, in this case the wood, will give out
the most heat and therefore melt more ice.
