ok so really it is quite simple. Methods are the same for res and curc.
So all you need is normal home brew gear plus a magnetic stirrer hot plate.
Start off by measuring powder in beaker to make 100 mg/ml solution. Add magnetic stirrer bar to beaker and place beaker on hot plate. This is when I turn on the heat. I don't know exactly what degrees, but it does need to steam a little to know you're at the high enough temp. So now the heat is barely on and going to be hot by the time my solvents are in, and I begin to add solvents. I use bb at 15% just to help a little but its possible its not necessary, but I do use it. Then add BA at 1.5%. Then comes the PEG400 and water. Now is where you want to crank up the heat so that it increases peg ability to dissolve the curc into solution. Use 50-55% water and 45-50% peg400 in place of where you would use oil in a regular homebrew. So like basskiller's calulator you can use and where it says oil that you need, that is where you would use that percentage ratio to make that volume needed. first you are slowly going to add the peg400 while the stirrer is now on a low/medium level like 200 rpm. Now add the peg400, and increase stirring speed, to the beaker and heat until light vapor rises from beaker, then keep at that heat and stirring at medium level, approx 700 rpm until solution appears to develop, signaled by the liquid not being in suspension but solution. . Now is when you will add the water. This you MUST do very slowly, literally drop by drop or you will brake the emulsion we have created. In the beginning you must go the slowest. This time you must also increase the stirring speed to approx 1000 rpms. Now begin to drop in one drop every other second right into the center of the stirring solution. Seriously this is where it is made or broken literally. If you add water too quick, you will brake the solution and it will separate. As you get furthur along putting more water into the solution, you will be able to slowly add at a faster rate, but be careful because again, it is easy to break. Now once all water is added and it is slowly producing steam (the heat is just past hot enough to produce steam, due to heat being where it needs to be, this is where i spun at same speed for 45 mins approx, not less tho but its possible you could. Also cover with piece of tinfoil during the 45 mins to reduce evaporation loss, but loosely cover so some can get out. After you add the water it will eventually in like 15 mins or sooner turn into nice deep red solution that is clear you can see right through a vial. Now its done. It cools to thick solution the curcumin, but its just like LK3 has stated. I use a 23g for curc and goes through no prob. 25g is tough tho.
Now the res water you do everything the same except you dont need to spin for as long or use as high of heat.
The only problem you should run into with making these using this method is 1 or two things. 1) heat isn't high enough so therefore peg solvent ability is not increased...This I had happen to me first time i made it, and after reading and applying, it worked. 2) You added the water too quickly, therefore breaking the solution. You will know its broken and no good when you see powder floating in it and not dissolved into clear see through solution.
Any questions let me know!
