Best Source uses industry standard sizing for its aggregate.


Best Source’ aggregate sizes correspond to sizes specified by ASTM and ISO.


Depth: Best Source aggregates achieve a wonderful transparency enabling you to see into the depth of the products. 

Shape: Most Best Source aggregates are similar in shape and have a fractured glass surface and not a flat, parallel surface. This multi-dimentional shape ensures a secure hold in epoxy or cement. Several of our aggregates are crushed bottles, window glass or crushed mirror.
