Description:
The quest "Glowstone Doped Silicon Boule" (no 194) states that you need nichrome coils to smelt glowstone doped boules, even though the recipe show it's smeltable at 2700 K aka Kanthal coils. The kanthal coil quest is even linked to it as a requirement.

Screenshots:

Have you updated your quest book recently? The current quest text says Kanthal.

Nevermind, the issue is just you're playing on an old snapshot. This was fixed in ecaa2a6. Update to a newer one.
