The 200mm-diameter vegetable (or vegie) sieve is a fine mesh sieve with a wooden handle, used to wash and sieve sample chips normally over a plastic bucket. They allow geologists to clearly identify the rock types when clean and washed.
For those that want extra longevity out of the sieves, we'd recommend the Double Mesh Vegie Sieve. This has a reinforced layer of mesh around the outside supporting the standard single layer mesh, making the sieve more durable.
Note: These are also referred to as field sieves, kitchen sieves or vegetable sieves.
