Guild Wars 2

Dulfy gives the following recipe for infused tempered spinal blades:

Infused version: 1 xxxx Tempered Spinal Blades + 10 Pile of Crystalline Dust + 1 Glob of Coagulated Mist Essence + 1 Gift of Ascension in Mystic Forge

Does it work on transmuted version, too? Or you can never infuse the spinal blades once transmuted?
