For mean seawater temperatures of 15–25°C, olivine sand (300μm grain size) takes 700–2100 years to reach the necessary steady state sequestration rate and is therefore of little practical value.

I too have found ramming necessary when using SS to bind Olivine sand. I use a common dead-blow plastic hammer. It does not ram like green sand as the SS sand will push up in the mold near an area I might try to really pack hard.
