Sand molding is a metal equipment casting method that provides a desired design shape to the end product by pouring molten steel or other metal into a sand mold and letting it solidify in atmospheric temperature conditions. The products produced by sand molding are made in specialized factories known as foundries.
Traditionally cast iron was cast in sand, link to a Wikipedia page about casting in sand. And I have also seen other metals cast in sand, like pewter and silver. And as indicated in the comments on the question, other materials can be used as well. Like plaster, ceramic, and even some kind of rubber for pewter.

The glass most people are familiar with is sodalime glass, which is a combination of soda (also known as soda ash or washing soda), limestone, and sand. Although you can make glass simply by heating and then rapidly cooling silica, the manufacturing of sodalime glass is a little more complex. By adding soda (sodium carbonate), the melting
Replace the pebbles with sand, so the proportions are 1 part cement to 3 parts sand. If you are making a small piece, experts say go down to 1 part cement to 1 part sand. Or, don’t add sand. Concrete sculptors say that the secrets to success are your creativity, willingness to practice, and to experiment. That goes for concrete, too.

Aragocrete is made from a mix of portland cement, aragonite sand, and water. This mix is formed into shapes and dried. After drying, aragocrete is soaked in tap water to hydrate it, called "curing" the aragocrete. Cement absorbs water and releases stuff that raises pH, alot. Curing aragocrete makes it safe to use in aquariums.
I made a batch about four months ago, using a mix of argonite sand and course shell grit that I bought from petland discounts for around $12 a bag. There is a complete step by step guide on the GARF website. garf They also recommend putting acrylic shavings into the mix to make the rocks lighter and to encourage coraline
fractions for glass making. BIS specification shows that (–600, +300) μm] fraction [A] should not be more than 50% and (–300, +125) μm fraction [B] should be 50% minimum. The mass percentage of A and B is found to be 29.9 and 70.1% (ratio =1:3.34) which satisfies the size specifications for glass making sand.
