Before hash had standardized quality terminology, the word full melt was frequently used without a consistent definition. Material that merely sizzled could be described as full melt, even when it did not melt cleanly. The six-star system was developed to bring order to that language, giving hashmakers and consumers a shared, observable standard.
Oakland: When Full Melt Needed a Definition
During the early Oakland hash-bar era, bubble hash was frequently described as full melt.
According to the original account, the term was often applied to material that produced little more than a sizzle.
Many consumers had never encountered genuine full-melt hash and did not understand what the classification was supposed to represent.
The challenge was establishing a way to evaluate melt without relying exclusively on someone lighting the product and describing the experience.
Bizarre Brothers and the Measure Z Hash Bar
Justin Benton, known as Space, and Josh Korpio of Bizarre Brothers Brain Taffy helped organize melt behavior into a standardized system.
The work developed through their Measure Z Hash Bar.
The objective was to establish a common language that could distinguish bowl-grade hash from material suitable for dabbing.
Importantly, the system separated melt performance from flavor preference.
A product could have desirable flavor without necessarily achieving the highest melt classification.
Jeff Church Helps Define the Standard
Jeff Church, called Dorky Jeff in the original account, played an important role in establishing the classification parameters.
According to the original account, his contribution helped clarify what the six-star designation actually represented.
The standard was based on two central observations:
How completely the resin melted.
How little material remained afterward.
Six stars were not intended to describe a brand, flavor preference or general impression of quality.
They represented a specific behavior under heat.
The Screen Becomes the Standard
Testing relied on tight-mesh stainless-steel screens.
These provided a consistent surface for observing how hash behaved when heated.
The original account also credits Dave Watson and BC Bubbleman with helping refine the terminology.
Their contributions helped popularize the expression clear dome, which distinguished genuine melting behavior from simple sizzling or bubbling.
The Six-Star Classification
The original system organized hash performance into six levels.
1 Star — No Melt: Does not meaningfully melt.
2 Stars — Sizzle: Produces a sizzle.
3 Stars — Half Melt: Forms a haystack-like residue.
4 Stars — Puddle: Melts into a puddle.
5 Stars — Clear Domes: Produces clear domes with a visible crater.
6 Stars — Full Melt: Melts completely through the screen with almost no residue.
The classification gave hashmakers and consumers a visual reference.
It also helped separate different levels of material without relying on subjective descriptions.
From Forums to Hash Culture
The system spread through online discussions, hash bars and longer educational conversations.
The original account identifies ICMag as one of the important platforms where the terminology circulated.
Conversations hosted by Shango Los featuring Cannabis Reverend, Jeff Church's identity, helped reinforce the definitions.
By 2016, star ratings had become common terminology within serious hash circles.
Rosin Changes the Conversation
The rise of hash rosin changed how consumers discussed solventless products.
As rosin became increasingly prominent, the traditional melt scale lost some of its practical role.
According to the original account, six-star terminology increasingly became shorthand rather than the result of actual screen testing.
Products were sometimes labeled six-star without being evaluated using screens, heat or residue observations.
This created confusion because the original system was designed specifically for hash melt behavior.
It was not intended to rate rosin or flavor.
Why Six Stars Still Matter
The original account argues that six-star classification should remain connected to measurable behavior.
It is not simply a description of a product's appearance or reputation.
The distinction matters because loose use of the terminology can weaken the meaning of the original standard.
The caption also notes that melt is not a complete measure of purity.
Some genetic varieties can leave a five-star-like film even when their resin is extremely clean.
For that reason, the account advocates additional repeatable measures, including screen performance and residue observation.
Legacy: Melt Is the Metric
The six-star system helped establish a shared vocabulary for evaluating bubble hash.
Through the contributions of Bizarre Brothers, Jeff Church and other members of the early hash community, melt behavior became a measurable standard rather than a marketing claim.
Its central contribution was separating genuine full melt from simple sizzling.
The system remains meaningful when used for its original purpose: evaluating how resin behaves under heat on a screen.

Puffin Farm's hash maker states flatly, "This system was created by the Bizarre brothers in Oakland CA to grade hashish at their measure z hash bar," and publishes the screen-based scale the draft reproduces: 1-star no melt, 2-star minimal melt, 3-star boiling into a haystack shape, 4-star boiling to a puddle, 5-star clear domes leaving a crater of bare screen, 6-star melting through the screen with almost no residue; all ratings are done on a screen, and 4-star and above is dab-grade, matching the draft's bowl-grade vs. dabbing distinction.

Church (a.k.a. Reverend Cannabis) is credited in the intro with working "to develop and implement the Medical Marijuana Hashish rating system for consumers and patients," and gives the 1–6 star definitions in his own words — 1-star basically no melt, 2-star presses and melts a tiny bit, 3-star melting into a lump, 4-star boiling flat into a puddle, 5-star big clear domes that push contaminant to the edges and leave a crater of bare screen, 6-star the consistency of hash oil — and confirms flavor was deliberately left out of the star rating system.

In Richardson's own first-person account, he and Skunkman Sam — Dave Watson — coined the terms at the Cannabis Cup's Pax Party House in Amsterdam in the early 2000s: "when it melts away like this I call it FULLMELT (the hash will drop down and melt like water, almost passing thru a tight mesh screen)," and at the highest quality "you will see Giant clear domes pop up out of the bowl. Thus the term Fullmelt Clear dome was born." He adds: "Years later my friend Jeff came out with a star rating system based on melt factor of your water hash. 1 Star being barely a sizzle, and a 6 Star a water like substance that melts downward."

This sourced history of bubble hash identifies David Paul Watson (Skunkman Sam) and Marcus "Bubbleman" Richardson behind the full-melt and clear-dome terminology, and states that "the star system used by the community today was invented by the hash maker, glassblower, and Bizzare Brother SPACE — also known as Justin Benton," dating his coinage of the system to 2016 and recording that Benton died in October 2021.

A current industry explainer confirming the scale remains the standard vocabulary: ice water hash "is rated with a one- to six-star rating system, with six stars considered the best"; 3–4 stars is mid-grade "half-melt" hash that leaves some impurities behind, and 5–6 stars is full-melt hash that leaves no residue behind.
