Pressed about 1/4 of my keif.
Maybe I'm doing it wrong, but my rosin doesnt look anything like the pic you posted. Im pulling extracts from the bubble hash and getting a thick honey like rosin, then I chuck the pressed puck of hash in the trash.
My method is: put pressed puck of hash into a coffee filter and wrap it up, then put that puck into parchment paper. Press the puck between the heated plates and collect the rosin concentrates from the parchment paper. It looks like the stuff in your pic is just warmed up keif smushed more than actual extract from the keif?
It took about 8-9g of bubble hash to get this 2g of rosin from it.
