yeah, I know. Maybe should have said "pearl" instead

hahem ... well it's not really better except if you are thinking of sand "biogène" wich is not really sand

I mean don't try to make glass with such a sand

Sodium Chloride bonding is so strong, it takes something damn beyond polar for it to bond with another solid. SiO2(sand) because of its nature(covalent bonding) is next to impossible to separate in everday situations such as yours. Meaning no bonding, no sticking together.

SI needs 4 bonds to be stable while each O atom needs 2 to be stable, thus 2 Oxygens bond with 1 Si. SIO2 uses 2 electrons for each bond (that is they are covalent) so it is tough and does not disolve in water.

my experience is if you cook anything long enough it either:
1. melts and then rehardens
2. hardens
3. catches fire

EDIT:

If I were you I'd try the PETA tard forum....they'd definatly know how to make this.

I think you can make hide glue if you find something dead on the shore.

1 cup collegen

1 cup water

3 table spoons of salt

heat these ingredients at 170 until thick, allow it to cool, mix in the sand, pour into mold, wait until it sets up, take out of mold, dry unlit hard.

Do not allow mixture to boil or get overcooked, as this will break the proteins in the collegen.

ps. this is very syinky, so do outside if possible.

I don't know where you are, but there are two options around here.

You can take the soft limestone and either grind it down to a powder, or put small chunks in a fire, then use the powder dissolved in water as a good binder.

If you have access to gypsum, grind/burn/powder it and you will have a good, but not waterproof binder.

Last, get cornstarch and dissolve it in water, that is what the sand sculpture artists do.

If you need to distill the water from the salt, you can make a small evaporator

1 large plate

1 small bowl

1 large clear salad bowl

put the salt water in the bowl, put the bowl on the plate, put the salad bowl upside down over the small bowl with the edge resting on the large plate, put out under the sun.

you should have pure water in the large plate and salt and whatnot in the small bowl when it is done evaporating.

These are also good things to keep on a boat, just in case you run out of water.

What about saturating it with water and freezing it with liquid nitrogen (simulate winter)?

Use sandstone

JB88 · « **Reply #29 on:** May 03, 2005, 11:00:11 PM »

interesting ideas guys, thank you very much!

i am also experimenting with epsom salts, but it still feels much like cheating to me.

alas, there may be no way around it.

i didnt know that the sand artists use cornstarch. im gonna give that a try tonight.

(i also have experiments going with seasalt and light plaster additives.)
