Newb Cube Question

[diablo1ks]

Hey,

I have only recently noticed the following v1:10 cube combinations:

1 Ort Rune + 1 Amn Rune + 1 Perfect Sapphire + Normal (Basic) Rare Weapon = Exceptional Rare Weapon
The item type is upgraded.

1 Ral Rune + 1 Thul Rune + 1 Perfect Amethyst + Normal (Basic) Rare Armor = Exceptional Rare Armor
The item type is upgraded.

1 Fal Rune + 1 Um Rune + 1 Perfect Sapphire + Exceptional Rare Weapon = Elite Rare Weapon
The item type is upgraded.

1 Ko Rune + 1 Pul Rune + 1 Perfect Amethyst + Exceptional Rare Armor = Elite Rare Armor
The item type is upgraded.

There are also unique combinations as you probably know... My question: Can I upgrade Set Items, Crafted Items or just plain or socketed items using any of these formulas? Sorry for such a newb question, it's just these formulas are new to me *slaps myself for not having a clue*

Thanks in advance!
