I looked up the size of the DMT Molly and then looked into Wire Mesh which is available and listed as to which micron size each screen is.
40 Microns is sufficient but I got 25 to be on the safe side and it catches the goods real nice.
This works WAY better than any 'Coffee Filter'[[ IMHO ]] because One can simply scrape the filtered goods off with a knife or razor blade and not get any paper fragments or tearing of the filter.
Also, sometimes the goods will melt right into the coffee filter which pissed me off to no end because I couldn't recover them.
With the Stainless Steel Mesh, after I scrape the goods off, there is usually some goods which melted into it.
So, I take vinegar and recover by rinsing the Screen out with it.
I have a bottle of Acetates recovered this way.
Someday I plan on recovering the goods out from it [[ The bottle of Acetates ]] and then after that, taking the remainder and converting whatever oxides might be present, with Zinc Dust.
Thats another topic for another time.

Sorry but I don't see why ppl use a jar to freeze precipe in and then use a filter to catch the dmt in , simply use a glass dish to freeze precipe in , that way the dmt sticks to the bottom of the dish and just gently and carefully pour of the nps off the top !!

Yeah thats a good point. I dont have any flat glass dishes though and besides, I like to form big chunky crystals that are easier to scrape off. I dont freeze precip the first pulls, I do that AFTER when I use a solvent mix. Freeze precip isn't needed with heptane BUT it can be done with the solvent after draining it away once it has cleared and all the crystals have finished forming. Then after it's strained, the heptane goes in the freezer and the other goods come out as free floaters and some settle on the bottom but not much.
I have found with the first 'harvest', after draining, When they are first 'hung to dry' while sticking to glass jar, they are choice pickings when the heptane is all off and they're dry. I find a small mason jar is just fine. The stainless steel screen is for the pulls AFTER the first 3 combined pulls, when the crystals are of a different form, like floaters or settlers, they usually are not the nice chunky ones gotten from the first 'harvest'.
After pulling with Heptane for mostly DMT [[ Heptane ,hot, pulls almost exclusively DMT I find ]] I go back and start over with a heptane/naptha mix to pull the rest and THOSE crystals remain 'free floating' for the most part and dont stick to the glass much or they settle. Plus, heptane evaps clean, naptha I find takes too long therefore the potential for melting the goods is higher, even if putting in the refrigerator after straining so the screen allows for complete drainage at a faster rate than evaporating.
So, a stainless steel screen DOES have it's merit, IMHO, because once pouring through the mesh you can put the screen itself in the refrigerator to finish draining/evaporating and then it's so easy to scrape off the screen instead of a coffee filter.
So, like I said, I dont use the screen for the initial pull results, like I have shared here in this photo. I easily scrape these big chunky beauties out no problem, even though it's a jar and I have no loss to yield.
The Pulls after, THATS when the screen is needed and in my experience using a flat dish for the floaters wasn't even necessary when I just dry on the Steel screen as is.

I completely agree on using the stainless steel wire mesh – gives us much more rugged and tough filter to use as opposed to the weak paper that everyone is used to with the coffee filters. – where were you guys ordering this screen from and in what quantity? I saw a lot of the micron sizes I was in need of here: Bellevill Wire ClothA and they also offered to send me out some samples of the mesh that they make and supply.

I'm not sure about whether or not we are allowed to share 'sources' but, it's easy to get the mesh online, I got mine on a very popular online 'store' that starts with an 'E' - The 'Stainless steel mesh 500 12 x 12 inch ' - it's about ten bucks plus shipping - it is also the finest and I THINK the micron size is 35 - which is just under the size of 'Spice' - It also works GREAT for Rue extractions, straining the Base or Salt really nice..so easy to scrape off too - I am new here so I'm hesitant to share the link where I obtained it but it's REAL easy to obtain and well worth it. Just do a search online type in the 'key words', thats all
