You guys forgot to add the fact that enchanted sheet metal is needed as well in this recipe. The following was taken directly from eqtraders.com:
Silvered Weapons -
appropriate molds, enchanted sheet of metal (from HQ ore), enchanted bar of silver, flask of water (use forged weapon recipes above to determine which molds to use)
(recipe orginally required that enchanted sheets of metal be forged only by human smiths in a human cultural forge. This was reported to have been fixed in June 5)
The following are NOT valid silvered weapons: two handed sword, ******* sword, morning star
To enchant the ore you need an enchanter with the spell that allows them to do it (enchant steel?) at level 49 or 51 I forget. Have fun.
