Shatter Project

Discussion in 'Concentrates & Processing' started by gateswood, Jun 5, 2018.

  1. Random buds. Strain is NYPD 70% sativa. Outdoor grown 2017 until it quit growing and then unceremoniously hung in a barn drying room before eventual storage of branches in coolers. It was untrimmed until I did the trim on the lot. Not skillfully or carefully trimmed but can attest it's very gooey requiring a lot of scissor and finger cleaning. The bud is potent to smoke. I saw the colors of a fire opal in the full, north country moon. It seems to have plenty of trichomes and hope it will make good BHO shatter.

    Can I please get an experienced SWAG (Scientific-Wild-Ass-Guess) on what the yield may be from this bud?

  2. I don't know about the experienced or scientific part, but a good place to start guessing with nug is 20-25% and that last pic looks pretty frosty, so definitely leaning towards 25%

  3. Wow, that would be an awesome yield. All the buds look pretty much like the macro pic on the bottom. All very gooey.

  4. Another question: What major characteristics would bud dried to 50% humidity be showing?

    These were 2017 outdoor, 15% average return on much better nugs than yours. Do you have a set up yet or is this all hypothetical?

  6. That's nice looking stuff. Do you have any macro pictures of the source material?

    The project is real and will begin next week. I have 9 oz of this material to learn with.

  7. nice swiss cheese look, care to share the details on that slab? temp and vacuum and length of time in oven?

  8. 3 different slabs, the bottom 2 slab pics were done at 105 for around 4 days, straight shatter. The 1st slab pic was only 3 days at 99 degrees for more of a terp preservation. Just depends on the material and what I feel like doing. If the terps are unappealing or even strange, I shoot to make terpless shatter. @aSilvrHaze
  9. I did my first extraction today. 14.45 grams of bud, clipped into small pieces with scissors and left to rest in a jar for a few days. I did the extraction in a 90 gram closed column. The half-Z more that halfway filled the column, very loosely packed.

    I stored the loaded column and butane in the freezer overnight. I put the first can in under vacuum and soaked 5 minutes before release. Second wash was one more frozen can into normal atmosphere within the column. Again, I let it soak for 5 minutes before releasing.

    A couple of things really surprised me about this operation. The herb came out dry and still has a fairly potent smell. One bud no longer stinks up a room but it does smell like there ought to be some goodness left inside. Is this normal?

    I do think I got most everything out of it. The bud lost 3.45 grams of weight and a quick and dirty measurement of what's now in the vacuum chamber indicates most of the weight is accounted for but I'm wondering if I should have ground the bud and/or left it to soak longer? I caught no crap at all in my filters. A 150 micron screen over a 50 micron screen on a coffee filter.

    Here's what the extracted bud looks like. Is this normal appearance for extracted bud?

  10. Here are my first two pieces of "shatter". From what I've read, the color is probably normal considering the age of the buds. Otherwise it seems nice. I've been holding the temperature to between 90 and 95° F so it has good terpene smell. I vaporized a small taste and it's potent.

    It will shatter when it's very cold but at room temperature it's kinda gooey. Push a tool in it and pull a string out of it. What can I do to dry this stuff and harden it?

  11. This is the only other shatter I've ever seen. Somebody sent me a gram and it arrived like this. Completely melted in March.
