Hey everyone I have browsed through the first few pages of this thread and there is some really impressive BHO in this thread. Certainly in a different league than anything I have produced. I have done a few small quantity runs in the 7-14g of starting product range and I guess the major piece of the puzzle I am missing is a vacuum chamber for the purging process. I do things a little bit different every time and have ended up with products that are like an oil, products that look like budder I have seen online, sticky gooey products and one time I ended up with a rock hard shatter like product.
This time it is looking pretty good, at the stage its in it is almost like a mix between shatter and budder (if that makes any sense). What I did was the typical blasting into a glass dish sitting in another glass dish of hot water. I evaporated all of the butane outside and then brought it inside when I was left with the sticky substance in the bottom of the dish. Brought it inside and did a few more runs with hot water to get as much of the butane out in that stage of the process as possible.
**I did make an unfortunate mistake at this stage and allowed a few small particles of herb to blow into the dish when the butane was evaporating. An unfortunate mistake but i'm not overly picky so i'm not too worried about it.
After the butane evaporated as much as possible I scraped out the oil and transferred it to a piece of parchment paper. For the next three hours I worked the oil on the parchment paper, squeezing the oil together then pulling the paper apart until it became less runny. At this stage the product looked really incredible and I wish I had taken a picture at this point. It was a very metallic looking gold color.
Once it was no longer sticking to the parchment paper I just started folding and squeezing it for another hour and ended up with this last night.
This morning after reading this thread I thought I should try some sort of purge method to see if I can get a little more butane out than I normally do. I decided to fold up what I had into a bigger piece of parchment paper and vacuum seal it into a normal food saver bag. I then soaked it in hot water at 120 degrees for about an hour. The water went from 120 down to 80 and then I refilled it and it went from 120 to 80 again.
This is what I ended up with now. Not a huge difference but it is a bit more transparent.
Any suggestions on how I can purge it a bit more without a vacuum chamber for this batch? I was thinking of buying one of those plastic containers made for the food saver's for next time, would that work?
