When you have a blacksmith make sure you have the basic things to forge (a anvil hammer and some iron/steel). Example of this is easier to explain heh. Oks say yuor makeing a sword (2 iron) you click the hammer, click sword then it will tell you how much iron it needs. Before you click ok take a look at bit just below it. Then from your inventory just drag and drop the elemental stone you want into that area. Stones = 30% less chance to forge and star crumbs = 10% less ^^
