Before you start dry-sifting, put your plant material in the freezer.

The two ways to make them involve manually separating trichomes with the dry sift and ice water extraction techniques.

For dry sifting (also known as flat screening), you will need a silkscreen or a fine metal mesh, usually made from copper or steel.

After the dry-sieve method, hand-rubbing is the second most popular technique.

It’s just as simple as collecting kief through dry-sifting, although the process is slightly different.

It works similarly to the dry sifting method, but it’s all done by a machine.

There are special dry-sift shakers or boxes you can purchase to simplify the process.

When using the dry-sieve method, the length and intensity of the ‘shake’ will also produce varying results.

The highest quality dry sift and bubble hash falls under the full melt extracts category.

Dry sifting your trim to separate the trichomes is another relatively simple method you can use.

If you’re using a box designed for dry sifting, there should be a second screen directly under the first one.

Popularised because of exportation throughout the world, hand-rubbed hash is almost as common in global terms as dry-sieve.

However, a dry-sieve or hand-rub method will never achieve the level of purity that can be achieved by using a more precise form of mechanical or chemical extraction.
