A simple suggestion; instead of "green glass" all over the place, allow basic-grade glass to be of a color correlated to the sand.

Regular/yellow sand; Green (so the color's still an option)

Black sand: Dark glass. (Dark grey)

Red sand: Red glass. (dark red)

White sand: Pale glass (light grey)

That is all.

Is that REALLY how it works?

So then I guess that is a no. That is not how it works.

How about a by-product of bar creation is 'iron residue' or something along those lines, which can be mixed using reactions into a glass creation, and making colored glass?

((The uranium glass is very interesting.))

Glassblowing promises to become much more interesting! Finally a use for all the different minerals. It would also have a nice overlap with other industries that use dyes and pigments, like painting and clothesmaking.

For the time being, it could be diversified into faint green, light green, green, and dark green.

Sand of different colours could come into play in the magic arc.

Also, for what it is worth, it has been suggested a few times already. Big surprise, given that we have some 300 pages of suggestions...

A chance to ask questions to a glassblower here.. http://www.reddit.com/r/AskReddit/comments/7kyfr/ask_a_glassblower_anything_youd_like_to_know_ill/

It yields interesting things like:

Its actually pretty hard to embed things in glass. The glass when being worked with is around 2100-2300 degrees, so most things just burn instantly. One thing you can get into glass is copper. Pennies work too sometimes, as long as they are real copper and not the zinc kind.

It is a glass plate. It is encrusted with a !!kitten!!.

The charred kitten corpse adds flavor.

I really gotta get started on the "Defeating unbeatable creatures" suggestion... (yes it is related)

Since glass coloration is generally done using minerals and chemical products of them, it would make sense for dwarves to use them, and it would give glass a nice value boost. I'm not sure how many of the common examples COULD be done, but certainly enough to provide some variety and use for currently-useless stone.

I'm bored, so here's a list of possible glass additives already in dwarf fortress:

Brimstone (Sulfur) -> royal blue
Brimstone + any flux stone -> deep yellow
Pyrolusite (Manganese) -> clear glass in small quantities, amethyst (purple) in higher quantities
Cobaltite (Cobalt) + Potash -> blue glass
Tin oxide (Can use tin for simplicity) + Arsenic (Colbaltite, Realgar, Orpiment, etc) + Stibnite (Antimony) -> white, opaque glass
Copper -> dark red, opaque glass
Copper oxide (Not sure how to differentiate between this and Copper) -> turquoise
Iron oxide -> bluish green
Iron oxide + Cobalt -> rich green
Nickel -> violet - blue - black, depending on concentration
Nickel + Crystal glass -> purplish
Nickel + Cobalt -> decolors lead glass
Chromite (Chromium) -> very dark green - black
Chromite + Tin oxide + Arsenic -> emerald green
Cadmium (Bi-product of smelting Sphalerite into zinc) + Brimstone -> deep yellow (toxic)
Silver (Mostly in the form of silver nitrate - not sure if it fits period) -> orange-red - yellow
Gold -> rich ruby color (known as Ruby Gold)

I thought I saw uranium oxide as an additive to make fluorescent green glass on the second wiki page somewhere, and there were more. Rutile, among others, is an uranium ore.

I'm not sure if cobalt or chromium would be smeltable, and I'm confused about "brimstone + any flux stone" - the flux stones are all very different, so how would they result in similar color changes?

Oh, and you could distinguish copper from copper oxide if, for copper oxide, you just use some ore made out of it.


By the way, keep in mind it isn't exactly clear what "crystal glass" is in DF. I don't think it's lead crystal glass, since that would require lead and probably wouldn't require rock crystal. My only guess right now is that it's simply very high-purity glass made from pure quartz crystals.
