is there a way to tell what mod an item/block originates from?

I have a number of mods and I know some of them added copper to the world. When mining I tend to find 2 kinds of copper ore, ones with orange dots (Copper A) and ones with goldenrod dots (Copper B).
When I smelt these two ores I get 2 different ingots. In IndustrialCraft when I crush Copper B Ore I get Crushed Copper Ore and when smelted I get what I would have gotten if I smelted Copper A ore.
Now I've been storing Copper A Ingots as blocks in my factory as I suspect that Copper B was added by RailCraft. When I went to get some of Copper A out of a block the ingots I got were a totally different colour to Copper A or B (but I could flatten it to make wires just the same as Copper A).
Now I would like to know which mod created not only the third copper ingot but the two different types of Tin Ore I've been getting. So I am wondering, is there a way to check what mod a particular block/item came from in game?
