Sand quality should affect glass quality and color

Well, yes--as long as there are methods of refining the quality of "found" sand.

Cleaning, heating, filtering, possibly treating it with acid, etc. Might be a task for the Alchemist's?

I was thinking more on the lines metal impurities giving glass color if not filtered out, not shifting sticks and bigger rocks out of the mix.    It is my understanding that white sand is better than black. Not entirely sure if you can even use all types of sand indiscriminately

Obsidian.
It have to be smelted into clear black glass. Dixi.

As for the sand as veins as the title states, it is mearly a matter of adding the appropriate entry to the raws to make it appear like any other vein.  In fact, just nearly copy and entry and adding the the sand tag should be all is needed if i am not mistaken.

Pilsu: Quality and color are probably going to be two different (if often closely related) questions, though.

There are, ofcourse, many different levels of filtering and refining, from the crude removal of impurities (separating sticks, rocks, dirt, organic matter; from a substance we would recognise as "sand"), and the not-so-crude purifying of that sand, to highly sophisticated adaptations, like lens glass, ballistic glass, or optical fibre.

It seems (to me) like it should be possible to-more or less-refine sand to a point where it becomes a basic, but very high quality material, for adding many different colors and other attributes to. What level of refining a DF alchemist of whatever skill level is capable of, is ultimately going to be up to Toady.

Color, on the other hand, is more likely to remain relatively constant, provided the chemical composition is identical--regardless of whether you're talking about a master glassblower intentionally coloring a flawless crystal goblet, or a lightning bolt accidentally coloring a chunk of half melted desert silt.

The crude shards of green bottleglass you can find scattered under a freeway bridge, and the fine Gibson uranium glass you might find in a gallery, are both recogniseable as green glass.

Again, the *quality* of that color--the purity, clarity, richness, depth--can be affected by refinement and adaptation of the ingredient substances, and the processes we put them through, but those are probably going to be slightly separate ingredients and processes, for each individual shade and hue.

Which comes the next point, different colored glass.  It would be interesting for glassmaker to make different colored glass (especially glass blocks), so it opens possibility to highly elaborate murals (I want stained glass roof).

I went to a glassblowing place recently, and melting glass is possible, but lets in impurities and is usually only used to help the other components of glass, such as silica, to melt, which speeds up the process greatly.

I think this is the question of time and game version, as the Toady already written some minerals used for coloration in ceramics.

Imo you shouldnt be able to tunnel through said sand veins it should collapse in an instant if you try to dig through.

1. Sand veins can be one meter height.
2. Why don't sand soil collapse? ;-)

3. I wonder why sand_soil tag won't work in matgloss_stone_mineral...

[Mayama]

Yeah it aways bothered me that you can dig through sand like its solid rock.
Sand should act more like a fluid but thats another suggestion ^^
