Blast into a large measuring cup instead of a pan and winterize in an ice chest with at least 10lbs of dry ice for 48 hours, de-wax with a Buchner funnel or a fry basket with a coffee filter in it, evaporate your bho pool into a very thick syrup, when the syrup stops bubbling in Luke warm tap water it's time to pour your slab onto parchment. Start your purge at around 90 degrees, achieve vacuum and maintain pull until muffin collapses (10 minutes to 6 hours depending on stability, you can collapse it after an hour if you get impatient) your first pull should be continuous for hours, after checking it out raise temp depending on stability (90 to 105 does most quality trim) and purge again, burping is optional in my opinion and I do it based on slab thickness. After about 2 days it's time to flip. Put on your gloves, peel up the slab, and put it upside down on a fresh piece of parchment and vacuum 2 more days. Flip one more time and vacuum 2 days and you should have insanely beautiful shatter depending on the trim quality and age. If your slab is too sticky to flip, put a baking sheet in the freezer and use it as a cooling table, this way the product will be easy to handle and flip without getting product wet, move quickly because the cold pan will condensate moisture after a few minutes of being in the warm air.
Pouring a slab instead of scraping greatly reduces agitation and even at higher temps you are less likely to budder. I just scrape my measuring cups afterwards for personal, it usually makes good shatter or pull snap, sometimes it makes super tasty low temp budder from the agitation of scraping, but it's usually about 3 or 4 grams and that's fine for personal smoke. You can scrape the de-wax from your winterizing cup too for edibles, but it's kinda gross (but effective enough). But yeah, pour your slab and you'll have much higher success with sensitive extracts.
Edit: keep electricity away until vacuum time! Don't use a hot plate to evaporate bho pool, use a dish with hot sink water, when the water gets cold, change it. Even a new hot plate will spark, I came home once to my old grow partner putting out a blaze in my kitchen because he was blasting in a kitchen with a hot plate. Never do any of those things! Lol.
