What is the Naked Press?
The Naked Press is a revolutionary rosin press for hash that operates without bags or parchment paper. It utilizes clean, non-reactive 316 stainless steel and glass for all major contact points with the input and output material, providing true 5μm filtration. This new method increases yield, streamlines the process by removing single-use consumables, and, when coupled with a centrifuge, can produce a pure, solventless cannabinoid isolate. All contact surfaces are medical-grade and GMP compliant.
What is the processing capability?
A single operator can process 500-1000g of hash per hour, which includes weighing, loading, pressing, and cleaning.
How does the return to rosin compare to traditional bag pressing?
The Naked Press typically achieves at least a 10% higher rosin return in a single press compared to multiple pressings of bags at different temperatures.
What about the terpenes and other volatiles?
The Naked Press process is guaranteed to retain a higher volatile content than traditional rosin pressing techniques.
What about oxidation of the rosin in the press?
The press has an option to purge with Argon or Nitrogen gas for an inert pressing environment. Proper ventilation and operation in a vent hood is required to operate with inert gas.
Do you have laboratory analysis showing the Naked Press is producing higher quality rosin than traditional pressing techniques?
Are you asking for a white paper that has great numbers on it, proving the Naked Press and Pressing Naked process is better than traditional pressing? Anyone can provide non-peer reviewed scientific looking documents to back up their claims. While we do not provide a peer-reviewed "white paper" to back our claims, we are willing to sign a legally binding contract to deliver the necessary hardware and operating parameters to reproduce the stated claims. The purity of the rosin has been demonstrated on social media platforms. For companies with an OCM license in New York State, material can be processed at a partner facility to allow for direct comparison with traditional methods and independent lab analysis.
What is the price of the Naked Press?
The technology is currently available for licensing at $30,000 USD, with an exclusive for 12 months offered for specific territories. The licensing includes Standard Operating Procedures (SOPs) for processing hash to rosin using the proprietary hardware.
How do I implement the technology in my process?
To implement the technology, send an email to hashcru@gmail(dot)com Your email should include your company name, contact information, and license/permit details. Inquiries are processed in the order they are received. Due to the high volume of interest, response times may exceed one week. A home-use version with 25-micron filtration is being designed but is not planned for release for at least 12 months.
How did the idea for the Naked Press come about?
First we need a history lesson...@asimnplebipedalobserver
The Evolution of Cannabis Rosin: From Forum Discovery to Global Mainstream
1. Ancient Roots: Hashish and Traditional Extraction Methods
Cannabis hashish has existed for centuries—its first mentions date back to 12th-century Cairo, calling out the “hashish-eaters” among the Nizari sect (later labeled the Assassins). Traditional methods—such as hand-rubbing, dry-sifting, and ice-water “bubble hash”—were long-standing techniques to separate potent trichomes from plant matter. These mechanical processes laid the groundwork for later, solventless innovations like rosin.
2. The Forum Genesis: Comphashon Coining “Rosin” (circa February 2006)
Online hash communities played a critical role in modern rosin’s birth. Around February 2006, IC-Mag forum member Comphashon (Chadwick Bastardo) posted a rudimentary extraction method—using heated stainless steel spoons and bowls—to separate cannabis oils from hash without solvents. He dubbed this discovery “Rosin”, inspired by the violin bow rosin he observed from his then-girlfriend’s violin and rosin bag
“Comphashon first came across this weird substance on the side of his double boiler… inspired by his then girlfriend… she had a violin and a rosin bag…” (@Greatgardener)
3. The Rosin Tech Revolution: Phil “Soilgrown” Salazar (Early 2015)
Nearly a decade later, in early 2015, Phil “Soilgrown” Salazar (aka Soilgrown Solventless) reimagined the rosin technique using a common household item: the hair straightener. Working initially with lower-grade bubble hash, Salazar noticed that when pressed under heat and pressure, oil would separate and become dabbable. Upon realizing the potential, he began pressing whole cannabis flowers, birthing what we now know as flower rosin.
By March 15, 2015, Salazar shared his method on Hash Church #25, soon others furthered the rosin technique with innovations like screen filters (e.g., tea bag tech, drip tech). This period marks a pivotal shift—from a niche forum trick to a replicable, accessible, and widely adopted extraction method.
4. Rosin Today: Mainstream Acceptance and Refinement
Flower rosin and hash rosin are now widely recognized forms of solventless cannabis extracts—made simply by applying heat and pressure to flower, kief, or hash. The method preserves terpenes and cannabinoids, offering a clean, flavorful product without using solvents.
In modern production, rosin is often created using hydraulic or pneumatic presses with precise temperature and pressure control—expanding far beyond hair straighteners into industrial-scale operations, and now we have the Naked Press that does not use nylon bags, parchment paper, or mesh wrapped hash. Variations now include “live rosin” made from fresh-frozen plant material, and post-press textures like badder, jam, various trade marked textures, and whipped rosin. Many dispensaries now stock rosin products, and competitive events celebrate the craft’s refinement and popularity. The technique’s rise reflects both consumer preference for cleaner extracts and broader cultural acceptance of cannabis concentrates
The story of rosin is one of grassroots innovation, born from a desire for solventless purity. It began with an ad-hoc experiment on a double boiler in 2006 by Comphashon and evolved into Soilgrown's elegant hair-straightener breakthrough nearly a decade later. This creative problem-solving led many to seek a nylon and parchment-free method for producing rosin.
Traditional rosin production involves numerous touch points that can introduce contamination. Recognizing this, I saw a need for a new process and hardware design that could reduce these risks. By adapting a device from another industry, I developed a solution that allows rosin to be produced in an inert environment, with only stainless steel and glass contact surfaces.
