Definition - What does Blasting mean?
Blasting is a term used to denote making concentrates, such as hash oil, by forcing a solvent through the plant material to pull out its oils. Butane is one of the most common solvents used to blast cannabis plant material. The cannabis is packed into a glass tube. Butane is then forced through one end of the glass tube and as it flows across the plant material, the oils seep out the other end of the tube.
Hydrolife explains Blasting
Blasting using solvents can leave a residue in the concentrate, which alters the concentrate's taste and can also be inhaled when the product is smoked or vaped. Many medicinal marijuana users avoid concentrates that have been created via blasting with a solvent.
Blasting using solvents can also be dangerous because of the flammable solvents. The process is sometimes referred to as open blasting. Closed loop extraction methods are a viable alternative to open blasting cannabis.
Blasting is a common method used to create butane hash oil (BHO). It is also used to manufacture honey, honeycomb, wax, glass, whip, comb and honey toast.
