Zoe,
When I was a guest artist in Latvia, right after the USSR break up, I
was given a lump of red earthenware and a lump of very high (^12)
chamotte clay. I was told that I needed to make some pieces for the
exhibition at the end of the month. I went to the Baltic sea , 2 blocks
away and gathered several bags of sand. I sifted the said. Added the
sand to the earthenware and chamotte. I came up with a stoneware that we
fired in an Olsen fast freddie.
Anyway, my point is this. Use the sand for a clay body and NOT a glaze.
Also, we used some sand from the beach in Spain. The pieces crumbled
AFTER bisque firing. I use a similar clay in Italy for Architectural
ceramics. It must be soaked in water within 24 hours of the bisque or it
disintegrates. Unless the sand is better than 200 mesh, don't bother.

You can make glaze out of anything if you can get enough heat onto it. It's
even easier if it's a fine particle size.
Beyond that, the answer is, as it always is in ceramics, "It depends". It
depends on the chemical composition of the sand, the particle size, what
temperature you fire to, what (if anything) you add to it, and on and on.
The only real answer is try it and wee what happens.

You would have to know what the sand was made of to really KNOW how to
use it. Some sand is silica, some is calcium based (sea shells, coral)
or some other rock/mineral. They all act differently.

Possible? I have some jars of sand from the beach that is a couple of
blocks from where I grew up. Can I make glaze from it?

ZoeJ,
i'm assuming your beach sand is silica (normaly), not calcite.
i used the following recipe. one of my coffee bowls at the
studio is with this glaze.
sand 40,
K-spar 60,
clay 10-15.

Hi ZoeJ
I'm afraid that the beach sand is most probably just course silica
(flint). It is a very useful glaze ingredient, but only if it is ground
up very fine . That will be slow hard work unless you have access to a
ball mill.
If you do and can, then just substitute it into any glaze recipe that
you already have that calls for silica, flint or SiO2.
Best wishes

Zoe, Next time you glaze, have your beach sand handy. Glaze your
pots in your favorite glaze, and very quickly, before glaze begins to
dry, sprinkle your beach sand on the pot, or you can even roll the
pot in the sand, although this takes some practice. You will get
some interesting results.
Good Luck.

sand" is actually red muddy clay.

I tried the following with sand ...and whee, what happened!
I cannot get fireclay here for the love of any diety.
I am still trying naked raku slips and trying to work out what to use
instead of fireclay. The last test was with
Aluminum Hydrate, Kaolin and beach sand dominating the mix. Tom B. helped me
to get these three ingredients together.
The slip hung on, and went through the firing well. When I began to chisel
the pots, the slip just slid off like wet sand, because I guess that it is
all it was. When the pots were very cooled down, I dipped them into the
fjord, just to get them completely cooled. The predominately sand slip
brushed off, no fusion or hardening of the slip, and beneath were very black
pots that shined up well with bee wax. They probably would have looked
exactly the same, if reduced without the slip on. The slip did not inhibit
the reduction at all.
Moving on to a new recipe with sand for the rough, but going back to
Zircopax instead of Alumina Hydrate. I got that slip to crackle, but the
pots were too wet that time, and blew up. I reduced some of the fired
shards and could see the process happening.
I did not think about posting this at all as it is not too astonishing, but
Paul's wee and the sand, well, put me in good spirits and made me talkative.

Careful when paking the kiln, the sand from the sand pots does not drop down
to the pots you may have in the firing that would not benefit from a dusting
of sand. Sand gets all over in the kiln and it is hard to see.

you could make all kinds of gritty,textured mixtures by mixing the
different sands with clay, with slips, and with any existing glaze.
Not too cerebral and definitely not too functional.

Philosopher's can spend a great deal of time arguing about what is real or
'real' or "real" etc.
In the meantime, perhaps you could in this instance dispense with test tiles
and move straight onto something fairly large, made out of industial
porcelain. Alternatively, you could simply place a sheet of litmus paper
over the target area and take careful note of any changes that occur.
