Silica also known as silicon dioxide is well known for being a very hard substance. It is most commonly found in sand or quartz and is the main ingredient in glass. Silica is also the main component of many of the bead releases that we dip our mandrels in!

In studies across Europe (Britain/France) amorphous silica has been found to be biologically inert when ingested and inhaled. Warheit ET Al found during that their bio assays that any minimal damage was reversible. In the USA the Food and Drug Administration has found it to be exempt from normal process and it is allowed in food and medicine.

Silica is harmless in other forms it is purely inhalation that can be detrimental to health.
