Quartz is not the same as glass. Sand made from quartz won't release silicates like playsand or pure silicate sand will! :hihi:Does all types of sand release silicates? Are some worse than others?
For example, I've seen a great looking sand called "unipac maui quartz sand". It doesn't say anything about silicates but isn't quartz same as in Glass etc which release silicates?

Ah ok.. so Quartz sand should mean it has NO or little silicates?If quartz sand releases silicates into water, all water on the planet would have lots of silicates in it. Quartz doesn't dissolve at all in water. Quartz is a crystal form of silicate, while glass is a non-crystal form, and also doesn't dissolve in water. If it did, any glass object kept wet would become somewhat frosted, and that doesn't happen. Water soluble silicate is sodium silicate - water glass - a different compound.
