Ice Water Extraction~

This method includes using dried flowers and plant clippings with iced water and “washing” the material to gather high potency resin glands for use as a concentrate.

When you isolate resin glands from other material plants produce, you get the purest dose of high quality resin that can be derived without using solvent-assisted extraction.

When you use iced water to make bubble, you’re using temperature, stirring, and wet sifting to isolate the resin glands.

The bubble production process involves putting plant material in a “work bag” along with plenty of ice, then stirring and settling the mixture for a period of time.

You’d be surprised how many resin glands are on leaves that get manicured off and thrown away. Water extraction is a way of getting more usable product from every harvest.

As an added benefit, water-washing removes contaminants and other materials that can affect your health. Because of this washing effect, ice-resin doesn’t have much, if any, taste or smell.

Icewater extraction takes a couple of hours, some preparation, ice made from pure water, and multiple steps.

CO2 Extraction~

Sub-critical CO2 is becoming an important commercial and industrial solvent due to its role in chemical extraction in addition to its low toxicity and environmental impact.

The relatively low temperature of the process and the stability of CO2 also allows most compounds to be extracted with little damage or denaturing. In addition, the solubility of many extracted compounds in CO2 varies with pressure, permitting selective extractions.

Subcritical carbon dioxide can be used as a more environmentally friendly solvent. Subcritical carbon dioxide is used as the extraction solvent for creation of essential oils and other herbal distillates. Its main advantages over solvents such as butane, alcohol, hexane and acetone in this process are that it is non-toxic and non-flammable.

Subcritical CO2 is chemically stable, reliable, low-cost, non-toxic, non-flammable and readily available, making it a desirable candidate working fluid.

Dry Ice Extraction~

Dry ice, sometimes referred to as "cardice" (chiefly by British chemists), is the solid form of carbon dioxide. It is used primarily as a cooling agent. Its advantages include lower temperature than that of water ice and not leaving any residue.

Just like with Ice Water Extraction When you use iced water to make bubble, you’re using temperature, stirring, and wet sifting to isolate the resin glands. Dry ice sublimates at −78.5 °C (−109.3 °F) at Earth atmospheric pressures.

This extreme cold makes the solid dangerous to handle without protection due to burns caused by freezing. USE CAUTION WHEN USING THIS EXTRACTION METHOD.
