Wax in Rosin

The benefit of winterizing rosin compared to just subzero ethanol refinement, is the color. Rosin removes very little chlorophyll (color). So after winterization, you'll get a more stable, higher percentaged THC, and still have the golden color. Same as BHO, which removes little chlorophyll, depending on age of material. Without the rosin, or bho extraction first, you'll have a black or hopefully green colored extraction. Oh Man green shatter is the shit! Gotta be in high 90 percents. No flavor or aroma really left though.

The straight ethanol winterization will always be a more potent extract. I know this for a fact, because I use my rosin chips in eatables, still PLENTY of medicinal value! BHO blasted has less value, but still some. Subzero ethanol refined material with a 2-5 micron Buchner glass filter has practically no value left. Makes a pretty blue flame though!

So no, winterizing rosin doesn't defeat the purpose, if you take a high value in the color. You'll have a much more potent rosin, and keep your color. Seriously though, the color don't make a shit! Winterized green shatter, in my opinion, is the most beneficial form there is. Likely WAY to much for most patients though!

Good point actually. You can get light colored product and not use toxic non-polars like hexane or butane, just alcohol for winterizing. BTW, I wanted to see if I could avoid evaporating alcohol by adding a bunch of water to iso. At first it just completely emulsified, producing a white liquid with no visible separation of oil. I then added sea salt to break the emulsion, at which point it separated out as a beige colored slime. I gathered a bunch up on a spoon by moving it around in it to get it to stick on. The rest stuck to the container, glass bowl. Long story short, I managed to get the water out without losing much product. It was just a small amount as a test.

After it dried out it was still a dark color but cleaner smoking than straight evaporated. With this method you get rid of the alcohol and wash out water solubles at the same time. If I had heated up the liquid instead of pouring it off, the oil may have melted and clumped together. I didn't try it that particular time. Actually you would probably have to pour off the water with the alcohol in it and add clean water and then heat it. Hot water with alcohol in it might dissolve some of the oil. And yes, drying the water out is not very convenient but it might be faster spread out on parchment in a vacuum with calcium chloride, which btw is also good for drying bud with no smell. You put some in a small container and sit it in a larger container along with some weed that needs drying and a small circulation fan on low speed. Without a fan it's incredibly slow but with one it's a lot faster. The rh in the container got down to 35% eventually. The calcium chloride starts to crust at first and then get liquid puddles in it. It will keep absorbing water until it's all liquid so there's no need to dump it out until then.
