haha, best to do is not stack ure ore, just melt it in 30 a piece, i once saw the succes change of melting each ore (tought on stratics). mayby u can peek there. mostly have nice guides etc. helpes me sometimes to make the best PVP char on my shard (how to make a pk if ure shard only have dexx PK's or only mages or teamers or whatever).

anyway, my tip for u is to just melt it while ure mining, wait till u have a pile of like 30 ore and melt it.
