oundry supply has silica sand more than likely, I used it when I worked in the sand foundry section of an art bronze foundry. Use with a lot of ventilation and or face mask. Mike Gordon

I'm getting a nice sand from Edgar Minerals in Florida - the same people
who mine and market EPK (Edgar Plastic Kaolin). It's a clean sand, somewhat
river-washed, so it has slightly rounded edges: gives strength and opens up
the clay without being too abrasive. Lots of meshes and combinations
available.

no, most beach sands are not silica, they are sea shells, calcium.  (ocean)

the best sand for pottery is commercial silica sand.
it has sharp edges and works as aggregate.  and it is clean.
home depot etc will have several kinds.
i never use play sand...dirty as can be.
and, you have no idea what it is??

the sand from the mid-east deserts are round.  perfect spheres.
they never use it for building.
like the snow of Antarctica...perfect circles...like marbles.
years of blowing in wind...rolling along the floor of the land.

i shipped 200 lbs of minnesota silica sand to dubai when i taught
there.  it was a god send.  i mixed it with local clay to make a very
nice local body we fired to cone 1.
