First claim
Opening claim text (preview).
What is claimed is: 1. A method to produce a cannabinoid glass from a decarboxylated cannabinoid extract, comprising: combining (a) a starting composition comprising a decarboxylated cannabinoid extract and (b) a solubility-regulating composition to produce a heterogeneous composition, in which: the starting composition comprises ethanol, a cannabinoid molecule, and a second molecule; the cannabinoid molecule is cannabidiol, cannabidivarin, cannabigerol, or cannabigerovarin; the second molecule is tetrahydrocannabinol, tetrahydrocannabivarin, or beta caryophyllene; the ethanol is a solvent of the starting composition; the cannabinoid molecule is a solute that is dissolved in the ethanol of the starting composition; the second molecule is a solute that is dissolved in the ethanol of the starting composition; the solubility-regulating composition comprises water; the heterogeneous composition comprises an aqueous phase and a lipid phase; the aqueous phase of the heterogeneous composition comprises at least 95 percent of the water of the heterogeneous composition; the aqueous phase of the heterogeneous composition comprises at least 95 percent of the ethanol of the heterogeneous composition; the second molecule has a solubility in the aqueous phase that is less than 10 grams per liter; the lipid phase comprises greater than 65 percent of the second molecule of the heterogeneous composition; the cannabinoid molecule has a solubility in the aqueous phase that is greater than 10 grams per liter; and the aqueous phase comprises greater than 65 percent of the cannabinoid molecule of the heterogeneous composition; (ii) separating the aqueous phase and the lipid phase to separate the cannabinoid molecule and the second molecule; and (iii) separating the cannabinoid molecule from both (a) at least 95 percent of the water of the aqueous phase and (b) at least 95 percent of the ethanol of the aqueous phase to produce a product, in which: the product consists essentially of the molecules of the aqueous phase that are separated from (a) the at least 95 percent of the water of the aqueous phase and (b) the at least 95 percent of the ethanol of the aqueous phase; the product lacks the second molecule at a concentration greater than 0.3 percent by mass; the cannabinoid molecule has a freezing point; the product comprises a glass; the glass comprises greater than 50 percent of the cannabinoid molecule of the product; the glass comprises the cannabinoid molecule at a concentration greater than 50 percent by mass; the glass has a glass-transition temperature that is less than the freezing point of cannabinoid molecule; the glass lacks a freezing point; and the glass lacks a melting point. 2. The method of claim 1 , in which: the decarboxylated cannabinoid extract is a decarboxylated full spectrum industrial hemp extract, a decarboxylated broad spectrum industrial hemp extract, or a decarboxylated industrial hemp distillate. 3. The method of claim 1 , in which: the decarboxylated cannabinoid extract comprises a plurality of cannabinoid molecules; the plurality of cannabinoid molecules comprises two or more of cannabidiol, cannabidivarin, cannabigerol, and cannabigerovarin; each cannabinoid molecule of the plurality of cannabinoid molecules is a solute that is dissolved in the ethanol of the starting composition; each cannabinoid molecule of the plurality of cannabinoid molecules has a solubility in the aqueous phase that is greater than 10 grams per liter; the aqueous phase comprises greater than 65 percent of each cannabinoid molecule of the plurality of cannabinoid molecules of the heterogeneous composition by mass; and the product comprises each cannabinoid molecule of the plurality of cannabinoid molecules. 4. The method of claim 1 , in which the cannabinoid molecule is cannabigerol, and the second molecule is beta-caryophyllene. 5. The method of claim 1 , in which separating the aqueous phase and the lipid phase to separate the cannabinoid molecule and the second molecule comprises gravity-assisted sedimentation of the heterogeneous composition. 6. The method of claim 1 , in which: separating the cannabinoid molecule from both (a) the at least 95 percent of the water of the aqueous phase and (b) the at least 95 percent of the ethanol of the aqueous phase comprises combining the aqueous phase and a second solubility-regulating composition to (i) drive a portion of the cannabinoid molecule of the aqueous phase out of the aqueous phase and (ii) produce a second heterogeneous composition; the second heterogeneous composition comprises a residual aqueous phase and a second lipid phase; the residual aqueous phase is a liquid; the residual aqueous phase comprises greater than 95 percent of the ethanol of the second heterogeneous composition; the residual aqueous phase comprises greater than 95 percent of the water of the second heterogeneous composition; the cannabinoid molecule of the second heterogeneous composition has a solubility in the residual aqueous phase that is less than 10 grams per liter; the second lipid phase comprises greater than 80 percent of the cannabinoid molecule of the second heterogeneous composition; the separation of the cannabinoid molecule from both (a) the at least 95 percent of the water of the aqueous phase and (b) the at least 95 percent of the ethanol of the aqueous phase further comprises mechanically separating the residual aqueous phase of the second heterogeneous composition from the second lipid phase of the second heterogeneous composition; and the product consists essentially of the portion of the second lipid phase that is mechanically separated from the residual aqueous phase. 7. A method to produce cannabinoid crystals from a decarboxylated cannabinoid extract, comprising: (i) combining (a) a starting composition comprising a decarboxylated cannabinoid extract and (b) a solubility-regulating composition to produce a heterogeneous composition, in which: the starting composition comprises ethanol, a cannabinoid molecule, and a second molecule; the cannabinoid molecule is cannabidiol, cannabidivarin, cannabigerol, or cannabigerovarin; the second molecule is tetrahydrocannabinol, tetrahydrocannabivarin, or beta caryophyllene; the ethanol is a solvent of the starting composition; the cannabinoid molecule is a solute that is dissolved in the ethanol of the starting composition; the second molecule is a solute that is dissolved in the ethanol of the starting composition; the solubility-regulating composition comprises water; the heterogeneous composition comprises an aqueous phase and a lipid phase; the aqueous phase of the heterogeneous composition comprises at least 95 percent of the water of the heterogeneous composition; the aqueous phase of the heterogeneous composition comprises at least 95 percent of the ethanol of the heterogeneous composition; the second molecule has a solubility in the aqueous phase that is less than 10 grams per liter; the lipid phase comprises greater than 65 percent of the second molecule of the heterogeneous composition; the cannabinoid molecule has a solubility in the aqueous phase that is greater than 10 grams per liter; and the aqueous phase comprises greater than 65 percent of the cannabinoid molecule of the heterogeneous composition; (ii) separating the aqueous phase and the lipid phase to separate the cannabinoid molecule and the second molecule; and (iii) separating the cannabinoid molecule from both (a) at least 95 percent of the water of the aqueous phase and (b) at least 95 percent of the ethanol of the aqueous phase to produce a product, in which: the product consists essentially of the molecules of the aqueous phase that are separated
