Craft Glass?

[RUMBLETiGER]

I apologize if this has already been answered someplace, I've done some searching and can't seem to find an answer.

How does one craft glass? In all the official Craft listed options, I've seen nothing with glass. Windows exist, glass vials, potion containers, beakers, and the like are all commonplace in the D&D world.

What are DC's and info for crafting glass?

Well, presumably you could simply have Craft (Glass / Glassmaking) or something similar, depending on how narrow or broad a skill you would want it to be. I would set the DC based on what the PC was trying to craft. Something simple, like a vial or beaker or something might be simple to typical, with a DC of 5-10. Probably a 10 for windows, figuring they are done from panes, and not a large single sheet of glass, which I would rule is more difficult. Something extremely artistic, like glass figurines, could be a DC of 15-20. Glass itself (making the actual glass from silica) should probably only be a DC5 for someone trained in this skill.

Remember, the rules in D&D are not set up to cover every single possible trade and craft the could exist. That is what a DM is for. It is your DM's job to determine this sort of thing.

Thanks for the info. I was just hoping that there would be official rules for glass. I mean, there's Craft-weaving! Glass vials and window panes have to be more useful than baskets for the typical PC.

Fun facts: It's simpler to make a pane of glass (traditionally a square or diamond a few inches across) than it is to make a glass container (vial, bottle, cup, etc). This is because a pane is essentially a vial that was mashed flat, whereas a bottle has to be carefully spun to ensure the air bubble inside the ball of hot glass stays put.

Making modern style windows with sheet glass won't really be possible without magical interference or 16th century technology (Float glass - Wikipedia, the free encyclopedia).

I'd raise the DC to a base 15 for just about anything, just because that's kind of the base standard for most Craft skills.

Oddly, clear glass is harder to make than colored or "smoked" glass. You need to purify your material more.

So while your "raw" material is simple sand you also need potash, caustic soda, or other caustic to extract the oxygen during processing, and other agents to counter the natural colors from your raw materials and to clean out impurities.

Sea sand will contain sodium borate, which makes nice sparkly glass, but also sodium chloride which you want to get rid of.

Lots of technical details, certainly enough that we don't need to get into them. All they do is set the DC for formulating the glass to begin with, and for crafting items from it.

To be most specific, the occasion that sparked this line of questioning was the Glowing Orb spell from Spell Compendium. You can make a permanent magic lightbulb that varies in illumination intensity depending on the creator's will or another individual with an INT or WIS of at least 13. The material component to this spell is a glass sphere, worth 50gp, an object with a hardness of 0 and 2hp.

I'm thinking, what would be the appropriate craft skill and DC to successfully make one of these?

I'd probably consider it to be a "high-quality item" from the Craft table, and go with DC15. And I think a Craft(glass) would be appropriate. You might even get away with Craft(Alchemy) if you assume that skill includes glass-blowing skills to make their lab equipment.

I'd find it more useful to make a glowing orb from a steel ball. Then you don't have to worry about breaking it if you drop it. Not sure your DM would okay you to do that, but I certainly wouldn't have any issue with it.

If he does, cast glassee(sp?) on the iron ball first to make it transparent.

Does 3.x even have that spell? I think that is just an AD&D spell isn't it?
