that custom ceramic wick was made by gdeal, if you want more info you can probably PM him. I can list quite a few advantages of ceramic over mesh because I vaped ceramic exclusively in my gennys for a long while. I started a thread back in feb called fc-2000 ceramic wicks and loved it until the micro's came along. although porous ceramic, imo, is probably the best flavor I have ever tried, it does have some draw backs, for one, its expensive and is very fragile, also its not easy to wrap. the coil needs to be very tight on the wick, and I mean tight, if not the flavor is muted. I know some have tried ceramic and found it no difference to mesh but if its wrapped correctly, there is no comparison imo. the best thing about ceramic is there is no possibility of shorts because of the non conductive material. another plus to ceramic is no oxidation required, also I believe its a safer wick compares to mesh. mesh if over oxidized can create some maybe harmful chemicals, like chromium, I believe, this is why in part the ceramic became popular some time ago. all in all ceramic isn't an easy set-up to make, because of the tightness needed on the wick you have to hot wrap it. using a torch, you wrap the coil while the wire is glowing, this basically melts the wire around the wick. also you can electrically wrap it, this is done by connecting the positive and neg leads to a power source and charging the wire electrically until it becomes super pliable, at this point you need to make your wrap quickly. if done correctly you will be rewarded with a flavor that is very pure and tastey.
And after going through that trouble, how long does the wick last and how easy is it to clean it? I just started to read info un oxidized mesh vaping safety. Makes me a sad panda, it tastes so goood! I overly oxidize based on Rip Tripper's recommendation stating in a video that you will usually get a mettalic taste out of a lightly oxidized mesh, he recommends to heavily oxidize so thats how I've done it. It also guarantees no shorts.
