well the time has come I did my first run with the bubble bowls kit that I got from bubble bowl kits.com and let me tell you it came out really well I am real happy with the outcome
I got a bag of dry ice from my local smart and final I paid $9.85 for 6 pounds it was $1.49 a pound plus tax I used a rubber mallet to break up the dry ice in small pieces before i used it
my first run I used 56.6 grams of trim which is 2 ounces and about half the dry ice I added the dry ice to the bowl before I added the trim and let it sit for about one to two minutes before I started to shake it
I shook the bowl for about one and a half minutes and collected it from the 120 micron bowl and 90 micron bowl in separate piles I them took the trim and dry ice in the bowl and put it to the side to do my next run with more fresh trim and more fresh dry ice
for my second round of fresh trim I used 87.3 grams of trim which is a few grams just over 3 ounces I made sure to add the dry ice first to the bowl them the trim shook it up a bit and let it sit for 2 minutes then shook the bowls for about 3 minutes this time since it was more trim and collected them in there separate piles
last I took the trim that was left over from the first and second runs and put it all in the bowls and did a third and fourth run just to get as much as I can from it these were low grade but still good stuff after looking at the pictures I can see I got a few pieces of plant matter in a few of them but its all good its all for me so it does not matter
now for the amounts I got from the runs
120 micron bowl first run - 3.0 gram
90 micron bowl first run - 2.7 grams
120 micron bowl second batch first run - 12.7 grams
90 micron bowl second batch first run - 1.3 grams
120 micron bowl third first run - 4.9 grams
90 micron kief from third run was less them 0.1
120 micron bowl fourth and final run - 1.9 grams
final numbers I started with 149.3 grams of trim and I got 26.5 grams of kief in total of different grades
