What full melt hash is
Full melt hash is a solventless cannabis concentrate made by separating trichomes, the resin glands on the plant, and pressing or sieving them into a hashish that liquefies completely when heated. No butane, propane, ethanol, or CO2 is used. The resin is collected by ice water, dry sieving, or static separation, so the finished product keeps the plant's native cannabinoids and terpenes.
"Melt" is the grading term for how fully that resin liquefies on a hot surface. A full melt sample pools into a clear, oily puddle and leaves little to no charred plant residue. Lower grades bubble, darken, and leave ash or a burnt crust.
Full Melt Hash Temperature for Dabbing: What You Need to Know
Why melt matters
Melt is not a THC percentage. It is a purity indicator. Melt reflects how much of the sample is actual resin head versus plant matter, broken trichome stalks, waxes, and leaf fragments. Intact trichome heads melt. Stalks and leaf do not.
Best Strains for Full Melt Hash
- Full melt (5 to 6 star): clear puddle, near-zero residue
- Half melt (3 to 4 star): partial puddle, visible residue
- No melt (1 to 2 star): chars, sputters, leaves dark ash
How to test melt at home
Prerequisites: a small glass or quartz surface, a torch or heat source, a metal dab tool, and a pea-sized sample.
full melt hash without a press
- Heat the glass or quartz surface until it glows, then let it cool for 10 to 15 seconds.
- Place a small piece of hash on the tool and set it on the hot surface.
- Watch the first 5 seconds. Full melt spreads into a translucent pooling liquid.
- Note the bubbles. Fine, fast bubbles signal resin and terpenes. Large, slow, sputtering bubbles often signal trapped moisture or plant wax.
- Let the surface cool and inspect the residue. A faint ring or clean glass indicates full melt. Dark crust or ash indicates stalks and leaf.
- Wipe the surface and repeat with a second sample to confirm the result.
What affects melt quality
- Trichome maturity: ripe, intact heads melt cleaner than immature or ruptured ones.
- Separation method: ice water hash, dry sift, and static tech all aim for head-only resin.
- Screen size: 73 to 90 micron screens catch prime full melt heads.
- Post-processing: gentle low-heat pressing preserves melt. Heavy heat or pressure can smear stalks into the resin.
- Moisture and cure: properly dried resin melts evenly. Wet resin sputters.
- Storage: cold, airtight, dark storage keeps the melt grade stable. Warm storage oxidizes terpenes and dulls the melt.
How to use full melt hash
Full melt is dabbed at low temperature on quartz or an e-nail, roughly 450 to 550 degrees Fahrenheit, so the resin vaporizes instead of scorching. It also works in a dry herb vaporizer layered between flower, or crumbled into a joint. Because it is solventless and aromatic, low temperatures preserve the terpene profile and the clean melt you paid for.
