// Definition
A solventless technique using liquid nitrogen (-196C) as a cryogenic medium to combine trichomes and oil, creating hash concentrates without chemical solvents.
// From the Episode
John discussed safety precautions extensively: liquid nitrogen expands 300x its volume, can cause severe frostbite if trapped against skin (inside shoes/socks), and pure nitrogen in lungs causes suffocation (nitrogen narcosis). Must use insulated gloves and work outdoors or in well-ventilated areas. The nitrogen evaporates completely, leaving no residue, making it technically solventless.
