I recall the Marsine used to craft the DRPG Stained glass. According to NEI it has no uses and the stained glass has no recipe. Unless this was changed to be a trade. Marsine doesn't seem to be used for anything.

Firestock and Veilo doesn't seem to have any uses either. I don't remember what they was used for in 1.4.7 either.

Veilo never had a use, it was going to be fuel in an experience condenser.

So Veilo is basically crud used by Leorna to scam people who think it has a use? It should be removed or given a use.

Lol. Yeah, the machine will be added, or the trade temporarily removed.
