==Procedure==

===Initial Steps ~~(feel free to change Nicole)~~===

===Initial Steps===

# Break up (not grind) the [[cannabis]] into small and loose pieces. This increases the surface area for the solvent and maximizes the amount of material to be extracted.

# Pack your extraction tube in a firm manner. Be careful not to pack the tube ~~over~~ as the butane must be allowed to flow through the material freely by the force of gravity.

# Pack your extraction tube in a firm manner. Be careful not to over pack the tube full of [[cannabis]] as the butane must be allowed to flow through the material freely by the force of gravity.

# Cover the open end with two coffee filters and secure with rubber band or clamp.

# Freeze your filled tube in your freezer in an air-tight container (this ~~prevents~~ condensation) for a ''minimum of 2 hours''.

# Freeze your filled tube in your freezer in an air-tight container (this minimizes condensation) for a ''minimum of 2 hours''.

# Once frozen, put on the protective gloves and mask and remove the tube from the freezer ~~and place~~ the pyrex or glass dish in a WELL ventilated space ~~(do NOT skip this part, see warning above)~~.

# Once frozen, put on the protective gloves and mask and remove the tube from the freezer. Proper protective wear is imperative.

# Begin pouring the butane into the tube from the small vent opening on one end. The butane should flow through the material to the bottom end and be collected into the pyrex dish. The tube will become very cold or frozen and ~~near~~ impossible to hold without heat-resistant gloves.

# Prepare the pyrex tray that will be used to catch the butane extract. Place the pyrex or glass dish in a '''WELL ventilated space''' This step is vital to ensuring a safe and explosion proof extract.

# Continue to pour the butane into the tube until it runs clear.

# Begin pouring the butane into the tube filled with [[cannabis]] from the small vent opening on one end. The butane should flow through the material to the bottom end and be collected into the pyrex dish. The tube will become very cold or frozen and impossible to hold without heat-resistant gloves or test tube tongs meant for extreme temperatures.

# Continue to pour the butane into the tube until the exiting butane lacks color and runs clear.

# At this point allow most of your solvent to evaporate from the dish in the well-ventilated space. Agitate occasionally at a safe distance.

===Final Steps===

# Once most of the solvent has evaporated, pour the oil onto a parchment or slick mat and place it into the vacuum.

# Turn on the vacuum and allow to reach full vacuum capacity which is typically around 29 in/Hg at sea level. The oil will begin to bubble and muffin up as the trapped butane escapes the chamber.

# Wait several hours for the muffin tops to fall and the bubbles to stop forming.

# Wait several hours for the muffin tops to fall and the bubbles to stop forming. This activity signals that butane is exiting the B.H.O. as intended.

# Once the activity has stopped place the chamber on the heat source and gently raise the temperature to 100-120 degrees. Be very careful not to add too much heat as this will burn off terpenes and darken the end product. Wait for any remaining bubbles to stop and remove it from the vacuum.

# Carefully try to flip the oil and melt it into the thinnest layer possible. Again take care not to add too much heat or fold air into the product as this will add moisture and trap in gasses which will affect the translucence and smoothness of the end product.

# Place the thin layer of oil back into the chamber at full vacuum. Leave on overnight.

# Repeat the final five steps as many times as necessary to fully purge the oil of impurities.

===Notes===

* Oil making is highly dependent on the strain. A wide variety of different looking products can result from this tek and may range from 'shatter' (the highest grade) to 'crumble' to 'wax' or anywhere in between. High THC strains often tend to "sugar up" and is prized by many for the smoothness of its vaporized taste.

* If you are looking to make a more crumble type product it is recommended to fold the oil into a tight ball and purge it repetitively over and over -- this will cause the oil to wax up, allowing bigger butane bubbles to form. The final purge of this oil will be with a blast of heat to let the large butane bubbles to pull out of the oil. '''Warning''': If this step is done improperly, some butane may become trapped in the almost solidified oil.
