What's the Difference between Silica Sand and Play Sand?

Moisture Retainment. Silica sand is ideal for projects requiring good drainage, as it retains less moisture than play sand. This feature makes it a better choice for use in aquariums and horticultural applications, such as potting mixtures and garden beds. On the other hand, play sand's higher moisture retention makes it great for building ...

5 differences between Silica Sand and regular Sand | M&C

Silica sand is composed of almost pure quartz grains, while regular sand is composed of a mixture of minerals such as feldspar and mica, along with some organic materials. This makes silica sand more uniform in terms of its composition, size, and shape. 2. Purity. Silica sand is much purer than regular sand because of its mineral composition.
