-Silica can be obtained [[In-situ resource utilization|in-situ]] directly from the martian regolith.  However is is usually mixed with contaminants and will usually require a separation process before it can be used for martian industry.  There may have been geological processes that have concentrated silica into easily usable forms.  Silica production for glass has en [[embodied energy]] of 6-15 MJ/kg.

 Silica dust is a known cancer causing agent.  Dust collectors and atmospheric treatment systems will be required in production areas.
