Full melt is a solventless cannabis hash, most often made with ice water, that turns to liquid and leaves little residue when dabbed. It sits at the top of the hash scale because it keeps plant matter out. The name comes from how the hash behaves on a hot nail or in a vaporizer.
Understanding Full Melt Bubble Hash
What is full melt?
Full melt is a grade of bubble hash, not a strain or a flavor. Hash makers use the term for resin that melts into a pool with little char. A true full melt leaves a faint ring or no residue after a low-temp dab.
Hash that leaves dark ash, bubbles hard, or burns is not full melt. Those batches may still work in a bowl or a joint, but they do not meet the melt standard.
What does six-star mean?
Six-star is a shop term for hash at the top of a melt scale. The scale varies by maker, so the label alone proves little. Ask for a melt test or a batch COA before you pay a premium.
How is full melt made?
Full melt comes from ice water extraction. Flower and trim go into ice water, get stirred, and the trichome heads fall through a set of filter bags. The collected hash is dried and sorted.
Cold water and gentle agitation keep trichome heads whole. Broken heads release plant oils and chlorophyll, and those hurt melt quality. Makers use freeze dryers or cool rooms to remove water without heat.
After drying, the hash is sieved and graded by size. Smaller, cleaner heads tend to melt better. The top grades are handled with cold tools and stored cold.
Full melt vs other concentrates
Full melt is not rosin, shatter, or crumble. Rosin uses heat and pressure. Shatter and crumble use solvents. Full melt uses water, ice, and screens.
Full melt vs bubble hash
All full melt is bubble hash, but not all bubble hash is full melt. Bubble hash can range from cooking grade to six-star. The melt test sorts one from the other.
Full melt vs rosin
Rosin starts with hash or flower and uses heat and pressure. Full melt is the hash before that step. Some makers press full melt into rosin to get a product with a longer shelf life.
How to test full melt
Do a small melt test before you buy or dab a new batch. Heat a nail or banger to a low temperature, apply a rice-grain piece, and watch the pool. Good full melt bubbles, turns clear or amber, and leaves little dark residue.
- Use a clean banger and a low temp.
- Start with a piece the size of a grain of rice.
- Watch the melt: bubbles, color, and residue.
- Wipe the banger with a cotton swab after each test.
A melt test can fool you if the banger is too hot. High heat burns any hash and leaves char. Use low heat and compare batches side by side.
How to use full melt
Full melt works in a dab rig, a vaporizer, or a hash pipe. Low temp dabs preserve flavor and reduce char. Some people top a bowl of flower with full melt for a slower burn.
Dabbing full melt
Use a low-temp banger and a small piece. Full melt can bubble up the walls, so keep the load small. Clean the banger after each dab.
Vaping full melt
Use a vaporizer made for concentrates or a device with a concentrate pad. Full melt can clog coils made for thin oils. Check the device specs before you load it.
Storing full melt
Store full melt in a glass jar in a cool, dark place. Fridge storage works for longer holds, but let the jar reach room temp before opening it. Moisture and heat degrade hash.
CBD full melt: what to check
CBD full melt is made from hemp flower with low THC. The label should list CBD, THC, and total cannabinoids. Ask for a batch-specific lab test, not a generic COA.
Lab tests should cover cannabinoids, pesticides, heavy metals, and microbes. A COA that matches the batch number tells you what is in the jar. Skip products with no batch match.
Full melt CBD hash can contain trace THC. Check local laws and the label before you buy. Hemp-derived products are not legal in every state.
What makes full melt good?
Good full melt has a clean melt, a strong smell, and no visible plant matter. The color can range from blonde to dark amber. Color alone does not prove quality.
Fresh hash smells like the source flower. A hay or chemical smell points to old material or poor storage. Melt quality and lab tests matter more than a pretty label.
FAQ
Is full melt the same as live resin?
No. Live resin uses fresh frozen flower and a solvent. Full melt uses water and ice, and it starts with dried or fresh frozen material.
Can you smoke full melt?
You can smoke it, but dabbing or vaping gives better flavor and less char. Smoke from any hash carries tar and irritants.
Does full melt get you high?
That depends on the cannabinoids. THC-rich full melt can feel potent. CBD full melt may contain little THC, but check the COA.
Why is full melt more expensive?
It takes more flower, more labor, and tighter handling to make hash that melts clean. Low yields raise the price per gram.
