Tricks & Tips To Make Full-Melt Dry Sift Hash


Bubbleman, an expert in the art of hash-making, reveals his tips and tricks for producing beautiful full-melt hashish. Learn the secrets to isolating the gland heads filled with cannabinoids and flavorful essential oils—all without the use of solvents or ice water.

The process of extracting full-melt, dry-sift hashish requires three separate screens. The example shown here is my Bubblebox, but you don’t need it to produce dry sift—only the screens. The box uses three, at 140u (microns), 107u and 70u. Three screens will give us just the control we need to produce the kind of full-melt dry sift that is, in my opinion, the holy grail of hash.

So let’s open up our Bubblebox and get started. If you don’t have a Bubblebox, you can order one at If you’re not as committed to having top-quality tools, you can buy just the screens for less than half the price. As you can see, the Bubblebox is built to last, with bird’s-eye maple and double-strength hinges. The screens come with a wooden cover on top and a set of keys to lock it when you’re done using it. If you decide not to purchase the box, you can get the screens stretched over frames by your local silk screener.

Using the Screens 

Originally, I created this box for people who didn’t normally make or even smoke any hash. I figured they could break up their joints over the screens and collect the resin that way. Really, though, what I unwittingly ended up doing was to teach them how to make great dry-sift hashish.

The top screen on the Bubblebox is 140u, which is the perfect size for gland heads to fall through. Some strains may have larger heads, but generally 140u is a safe size for the top screen. Breaking up your nuggets into powder is ideal for dry sifting, and this top screen will keep the majority of the plant material on top while allowing resin glands and other particles to fall through.

Using a stiff card, gently rub the cannabis over the screen. (I used my ski-pass card here, but any rigid card will do.) Be sure to get as much of the resin to fall through as possible. Just remember when you do this that you’ll also get a lot of contaminants passing through the screen. But that’s okay—that’s the reason we use several screens, even though it makes for a longer cleaning process.
