Listen og.. you can spout off about "expensive equipment" all that you want. It does NOT refute or disprove the information posted.
"Hash" is and
has been the process of collecting and pressing of trichomes for
centuries.
You aren't going to change the facts.
If "your" keif doesn't press, "you're" doing something in the process to muck it up.
"The quality of hashish depends on the quality of the plants used and the sieving and pressing procedures."
If your screen mesh is too large, you allow an excess of plant material to contaminate your "hash".
If the product that you use is inferior, the 'hash' will reflect it in the quality.
THC is NOT water soluble. That is why/how bubblebags work.

--- LPI is lines per inch, which is the same as U.S. Mesh. In real world applications in the United States, silk screen may be sold simply as 155 mesh. This would be the same as calling it 155 lines per inch, or 155 U.S. Mesh.
--- A micron is equal to one twenty-five thousandth (1/25,000) of an inch, or one millionth (1/1,000,000) of a meter. A millimeter is equal to one thousandth (1/1,000) of a meter.
--- Screen mesh made out of multifilament polyester should not be used for sieving hashish because it is not as good and will not last as long as other types of mesh materials. You can tell multifilament polyester by a mesh rating with xx in it. Example 10xx, 12xx, 14xx, 30xx plus, etcetera.
--- When making hashish, you can vary the mesh size from about 65-125 microns (about 120-230 lines per inch). If the particles are larger than 125 microns, they are not very potent. As the particle size decreases down to 125 microns, the potency increases.
At about 125 microns, the powder is what most people would consider good hash. The potency increases as the particle size decreases down to 65 microns. At 65 microns, the trichome particles are at a point that most consider optimal. Particles smaller than 65 microns tend be broken or immature trichomes (medium potency).

There's no "poo flinging" going on. Any time that incorrect, misleading, or simply false information is posted here, you can just about count on it being challenged, refuted.
We have a pretty knowledgeable and experienced collection of members at MP. Not a lot of mis-information is allowed to 'slip' by this crew...

I was seiving keif and processing iso oil 15 years ago. I purchased my 7 bag set of bubblebags about 5 years ago. I have ran
dozens of batches through the bags, and have studied/observed the results under magnification. They collect and separate/sort the 'trichomes' by size. Just as a proper "seiving" process does. "Pure melt" 100% pure trichomes from bubblebags is absolutely the finest form of "hash" available.(see the "subcool thread) I'm not just blowing air out of a hole in my neck, I know of what I speak.
