Definition of sharp sandCategorized under "General"
Definition as written by Terry:
An angular-grained, jagged sand, not rounded like beach sand. It is often recommended (in large quantities) as an amendment to loosen clay soil (along with compost); or to mix with sphagnum peat moss to create potting or starting medium.
It is also called builder's sand, although the two terms are not technically interchangable (sharp sand has a wider variety of grain sizes; builder's sand is mostly meidum to coarse grained.)
Where purchased, it should be free of clay, loam or other particles. If using it for potting or starting medium, you may want to rinse it, using a piece of fine screen to remove any sediment or other particles.
