Hello dear hash lovers,
long time no see.
Dear Frenchy, I have some views to share about dry sieve pressing.
I have a 4 piece grinder with a sieve of 140µ.
I managed to tweak a brush with not too soft hairs to clean the sift from time to time [ not too often and gently... always be gentle]
thus making I can collect around 1gram by month.
Tiny amount but good for practice and here is what I've experienced and overall learned from errors.
The biggest mistake was timing for pressing.
This is the opposite as how I proceed for ice extracted hash.
First time I pressed too long. I used the technique for ice hash and it was a fail right the next day.
I pressed it once and twice and thrice, rolled this 1g to a cannoli then in the jar for the night.
the next day, the cannoli felt apart, as soon as I touched it, it was back to powder trichome state.
Too dry maybe...
So I remembered a previous fast press with some dry sieving and I know it was a success.
By this, my next guess was to press with the bottle and warm water just the time for trichomes to melt together.
Then I decided finishing to press it by hand and turn it into a nice ball [1gram is few, ball shape is best for saving].
It took me about 1 minute of pressing.
when I saw the trichomes melt together and equally done,
It was time get it out of the bag, then roll it carefully and finish by pressing it and repressing, like you would do for a "mille feuilles" in bakery.
For me the most obvious way to know if you are good, is the moment where you get it out of the bag, freshly bottle pressed.
if it shines at some parts, well done.
It means you can finish it by hand with no failure for storing.
when I pressed too longer, the brightness was gone. [and fall apart next day]
I will do my best to take picutres next time I'll do some dry sieve pressing.
I hope this long lecture is not too boring and can bring something.
Cheers
