Get a silicon baking sheet from a store that sells kitchen gadgets. I got one that's 16x11". Canadian Tire sells them here.
I've always just used a pyrex pie plate or measuring cup if I blast thru a tube. Can sit the pie plate on top of a pot of simmering water to get the last of the butane out with stirring. Let the butane boil off at room temp before heating it at all then over the hot water to get the very last out. Been doing that for years but prefer to use boiling balls and distill the butane for reuse to get more mileage out of each can. Can do about 4x as much per can as blasting and letting it all evaporate. Tricky tho.
Heating this up to inject into vials with a glass syringe and short, blunt needle.

don't bother.look into rosin or old fashioned hash making.

apologies if I sounded like a dick.I just think it's over rated and it's being done by too many people who don't know how to do it safely or have the right equipment to do it safely.I was in Colorado not long ago and the shop had oil cartridges strictly co2,so that's a sign to me on top of what I already kind of felt uneasy about.I may catch flak for my opinion,that's fine.I just don't think the dude at home is purging off all the butane completely/safely.

Cooking that shit is definitely dangerous... dabs are nice on occasionally.. but I'd have to agree that they're overrated.

I maybe should have specified. Flat-bottom boiling balls to distill the butane from one to another into the deep freeze connected by a 20ft coil of copper tubing. I basically keep everything int the freezer the use the butane like it was ISO. Soak the pot in a mason jar with butane then filter it into a boiling ball, put the stopper with the copper tubing leading into the freezer to another bb to collect the butane that boils off leaving the BHO behind. Rinse and repeat with the captured butane.

Most people shouldn't mess around with highly flammable/explosive stuff like volatile solvents but I'm not most people so I'm OK. I let the bulk of the butane boil off at room temp so there's not enough left in the oil when it goes into the plate to cause a fire. I also have a diploma in chemistry and worked as a chemist in a hazardous waste facility for a few years.
I built a still that holds a whole can of Coleman's camp stove fuel so I can cook it out and get the naphtha leaving the gunk behind and use it for cleaning up ISO extracts or for extraction from pot. Make EverClear with it too.
Homedistiller.org for all sorts of info.

Well I'm no chemist but I'm not a dummy. Of course I want the cleanest product for my customers.
That's why I'm here. I need to figure out how to do it right.
So far I'm thinking I will get this closed column thing. I can add butane inside in a porch area with no electricity. If there is a problem I'll stop and let it blow out the door. But the closed column should hold it all in safely. When I'm ready to open it up I will do so outside away from the building and into a Pyrex floating in warm water.
Then let it boil off until it's safe to go inside.
From there I will have a vacuum pot on top of some sort of heat source and vacuum it til it's clean.
Sound about right?

Sounds about right as long as this closed column can hold the pressure. Butane boils at -0.5C so when I do mine everything has sat in the freezer for hours and the butane is liquid and can be used like ISO.
If you shoot the butane into a warm column it will turn into a gas right away but I'm not sure exactly what you're doing so no use babbling on atm.
I've never worried about purging. If you live in a city you probably breathe in more hydrocarbons that are a lot worse than butane residue in a day than you'd get from toking a whole oz of BHO. Standards must be set tho for consumers to be safe and that's a good thing.
The whole concept of using heated and vacuum purged oils as medicine sounds wrong to me. Most of the terpenes are lost and they have as yet unknown synergy with the various cannabinoids so whole plant extracts that are made without volatile solvents sounds to me like the best way to medicate.
If getting high is what it's all about to you then BHO is the way to go. As far as I'm concerned dabs, shatter, wax etc is for the stoners and there's nothing wrong with that. I just prefer to be able to medicate without getting legless so I'm personally more into hi-CBD pot and medibles as my lungs are shot from almost 50 years of cigarettes. Then after a small stroke almost 4 years ago the buzz isn't as much fun as it used to be. The hi-CBD cocobudder gives me a high like being drunk and I can get behind that!

Funny how this phrase has become the boiler plate cookie cutter response to any questionable bho. Sounds like tobacco lobbies circa 1960'sI've never worried about purging.

Since we already breath hydrocarbons, dosnt it make sense to NOT purposely add even more hydrocarbons to our "diet" and to be fair to those hydrocarbons in our atmosphere,your not putting them in a pipe lighting them on fire and inhaling.
Butane found its way into our cooking products years ago in part thanks to the folks at pam cooking spray.
Some may remember areosol cooking spray getting a bad wrap and falling out of favor about 25-30 years ago when it came to light that the ingredient listed as "propellent" was actually butane. That caused major consumer uproar. When labels read
Ingredients:
Canola oil, butane
Most consumers and moderately intelligent people stay away.
Personally id rather use lard than mystery oil
so that was a major kick in the nuts to the stock holders of pam.
This forced the producers to spend millions on study and go to the fda for approval and determination of safe residual levals. Most consumers just stopped buying areosol cooking spray so these days, most areosol food products now use alternative non voc to propel heavy things out of cans.
The basic argument given to the masses for the use of butane as food propellent,
It only takes a few butane molecules to push out enough oil to coat a pan and that pan or cooking dish is to be heated
Now keep in mind you are shooting whole cans of butane through that tube and not distilling off the residual under the high heat of a frying pan. How many cans dose one use to produce an ounce of wax or shatter?
You likley enjoy the effects of your hi cbd eddibles because you are enjoying the mixture of medicinal oils and their combined effect which are much longer lasting, medicinal and all around better medicine. Shatter is on average 70-80% thc and ????
18-25 year olds are the main consumers because in most cases they just dont know any different. Shatter is what the dispensaries and pop culture marketed to them. They were born into this bho generation. Its all just marketing.
I believe still mostly a North American phenomenon

thank you. I use a tamisium with heat lower than 100f. I recoup most of my solvent to use the next time. if I had to cook things and like a chemist I'd be skeered to do it at all. I feel relatively safe now, no heat, no pressure, like blasting in a sealed space, no hiss or pop or chem lessons. I do use some frozen plastic cubes to facilitate recoup, and my units pieces are often found in the freezer. I've got a small silicone heating pad that dials in accurately for heat. I like cold ntane, cold weed personally, have used some warming techniques too. mine comes out pretty good to me, and compared to a honey bee its heaven here, resolved 100% of my xtract issues. I liked the dabs alot a few years ago but vaping buds and puffing a joint is my preference. I do enjoy my polen sifter(amazoncom) for some fine keif occasionally too.I maybe should have specified. Flat-bottom boiling balls to distill the butane from one to another into the deep freeze connected by a 20ft coil of copper tubing. I basically keep everything int the freezer the use the butane like it was ISO. Soak the pot in a mason jar with butane then filter it into a boiling ball, put the stopper with the copper tubing leading into the freezer to another bb to collect the butane that boils off leaving the BHO behind. Rinse and repeat with the captured butane.

I'd be more concerned about the canola oil part of that short ingredient list. There's a toxic substance for you and made me stop eating deep fried foods years ago as almost every restaurant in the world uses it. Don't miss fries at all or the toxic soft drinks that I used to wash them down with.
When I was in that 18-25 yo range getting high was what it was all about for me too. Now I try to avoid getting too high but kids being kids and all that eh.
As I am about the only consumer of any of the things I make from pot I'm not terribly concerned about minuscule traces of something fairly benign like butane in my extracts. If I were to make it for wider consumer consumption then I would get into something like critical CO2 extraction but that's not a goal of mine.
I was smoking honey oil back about '75 that was the wonder of the day and now it's various higher grades of the same thing that has it's rabid followers. Life goes on.

I like my dry sift too and like to blend it with oil to make a nice black hash reminiscent of that old Temple Ball hash we used to get back in the late 70s. 1g oil to 4 or 5g kief. Cook that up in the pie plate over the pot of hot water.
Great for making cookies too. About 1 Tbsp of kief will make about 20 cookies that only take one to kick my ass. Seem to decarb great while baking.
I use these Endecotts particle screens to make my dry sift. The finest I have is 180 micron and have been meaning to get finer ones for years but they're good enough for me.
I've kind of drifted away from BHO type extracts and prefer making cocobudder that captures all the medicine in the plant and can be eaten or rubbed on the body. I only roll joints for company and just do small one hitters in a pipe when on my own.
Tastes change over time and I'm sure I'll be doing something else in a few years.
