risk? what do you mean by this..? and really thanks for telling about it.
remember, nicotine is more deadly than arsenic on a mg per mg basis, so you need to be careful with it...it is a poison (they use it in pesticides, it can kill, especially at high concentrations sometimes used for DIY)
I'll copy the info from post intro post, read it through and it'll explain everything!!
Short Primer on Mixing for Newbies
Due to popular demand, here is a simple introduction to mixing for the complete beginner. If you're new to E-Cigarettes in general, first check out the ECF library and learn about liquids and PV's before getting into DIY.
Other DIY guides: German (AlexTM)
1) What is DIY?
DIY stands for "do-it-yourself." Just like fixing something yourself, it's usually much cheaper. The basics of mixing liquids is fairly simple, and the large variation in peoples' taste buds makes DIY e-liquid a common choice amongst experienced vapers. However, if you're just starting with your PV, it's best to buy some pre-mixed flavors first while your taste buds rejuvenate after stopping cigarette usage. This will also help you decide what type of flavor you prefer - some people think they won't like nutty flavors or fruit flavors but vaping flavor is not the same as food.
2) Where do I start?
Read this guide! Actually, the easiest way to start is something you can probably do without ordering anything. If you have a recently finished or nearly finished bottle of e-liquid, just grab another flavor you have that you think would taste good with the old one. Add a few drops of your newer e-liquid to the remaining bit of the old one, and voila, you have a new flavor you made yourself. If you like it, write it down! Keeping a record of your mixtures is important so you know which ones to never repeat and which ones you loved (or were at least on the right track with).
3) Seriously, what do I do first?
Read, read, read. Then make a list of materials you will want. Dan has a DIY materials guide for new mixers in the library. You'll need empty bottles, syringes with low gauge needles, droppers/pipettes, unflavored PG and/or VG with nicotine (unless you are going 0 nic), pure PG and/or VG, and flavoring. This is the BARE minimum, but remember safety is very important. Syringes provide more precise measurements than drops so you don't get too much nicotine or unreliable mixtures, but they're also easier to use when mixing larger batches. Other important tools are latex/nitrile gloves for protection, isopropyl alcohol for cleaning, trays to catch spills, and tweezers. Optional stuff includes graduated cylinders, funnels, menthol crystals/drops, PGA for insoluble flavors or diluting liquid that's extremely thick (distilled water can do this too), Sucralose/Stevia, and Ethyl Maltol. This nicely formatted spreadsheet can help you pick flavors.
4) Wow, where am I going to get all that stuff?
Pamster has compiled an excellent DIY Vendor Supplies List.
A lot of it comes in kits from DIY suppliers e.g.: DIYFS, OneStopDIY, eCigExpress
Quality unflavored nicotine in VG/PG: XtremeVaping, MFS, lots more have sprung up recently.
WARNING: When you start out, try to get LESS than <60mg/ml nicotine PG/VG (that is the concentration of nicotine in weight per volume [w/v]). Higher concentrations can be extremely dangerous, even fatal.
Search sites like eBay and Amazon and you can find lots of stuff.
Most of the equipment (bottles, syringes, funnels, gloves, etc) can be found at US Plastics.
Various bottles: Glass - Specialty Bottle, Plastic - CandleChem, Both - Sunburst.
Other materials can be obtained at local stores like Tractor Supply, which carries PG. Walgreen's carries syringes and pet stores often have useful materials as well. Perfumer's Apprentice carries most of the optional stuff, but is constantly expanding their selection. You can always look through the suppliers section for more options as well as sales/coupons. If you want a more extensive list, see step 6. Also, Scubabatdan's calculator has some information on where to buy what.
5) I got my stuff, what now?
Even if you're experienced, it's a good idea to test individual flavors by themselves before jumping into advanced multiple flavor mixing. There's a thread on how to go about testing flavors if you have a lot you want to try. There are a variety of calculators (even an iPhone app) to help you get the amounts correct, 5 of which are usable offline that I've uploaded to a drop.io center. Dan's Excel version covers pretty much anything, but if you can't use Excel there is an old offline calculator app (.exe) and a newer one by breaktru software. The third is a simple Excel calculator by Switched, the fourth is by ddavelarsen. There is a very simple web calculator here, and a slightly advanced one that can handle multiple flavors here. Search the forums for more specific information such as recipes and you'll likely find what you need. Start off mixing small amounts, and use low amounts of flavor (if the guide says 10-15%, start with 10%) then work your way up if it's too weak. It's easier to add a drop of flavor than another 2ml of all of the other stuff. Also, concentrated flavors take time to diffuse throughout the liquid even after much shaking or stirring, so don't vape it immediately or you may be wondering where the flavor is. I tend to wait at least 5-10 minutes PER ml (so 2.5-5 hours for 30ml, or 15-30 minutes for 3ml). Even non-DIYing fans of made-to-order liquid say that letting it "age" improves the flavor.
