Not chips, but if you shine a light and look closely, do you see any flakes/bumps on the texture? I can't get a photo with good enough resolution...

Knowing that, does your SSV share similar findings?

I did contact them, but no response. Does your DBV have any streaks on the rod? If you look closely, are there any flakes or rough parts on the texture?

There is a chance for that to be the case, other DBV/SSV owners may be able to confirm this if their units show similar findings. I tried contacting 7th floor but no luck. I really want to use my vape without worries...

Thanks for explaining that, I don't want to annoy the thread by asking questions I probably should have learned in science class back in the day. I am worried enough that I have stopped using the DBV, but it was my favorite device. I am also worried because some of these flakes, are bonded...

So oxygen passing through the rod causes oxidation, which can result in a dust/sand. I wonder if this is with every rod, or if my DBV is defective. It wouldn't seem that people would be inhaling off a ceramic rod, knowing that this happens. Also, if it's sand, would living on the beach be more...

Thanks, that was a very helpful response. I never knew that wires ran inside the rod, to me the black lines looked like surface cracks because they were inconsistent with each other. I now need to look up what silicon dioxide is, and how that might be resulting in this. I would love to hear...

I do run it through water. And that's not the point. The point of this thread is to discuss what is happening to the ceramic, let's not turn this into a trollfest.

It's not about whether or not it's going to get through a loaded bowl. It's about what is happening to the rod, and what risks are presented. In this case, there are black lines and flakes that are unexplainable. Is this the heating and cooling of the rod? Did the rod crack? Are these flakes...

I have realized that, but still, if pieces of ceramic are breaking off of the rod during the heating process, I am hoping to learn more. If this was the case, this would mean that you can inhale these, and I wouldn't want to find out that 10 years from now using my vape actually hurt me more...

Too big to get into lungs? I didn't know there was a size limit. I also don't know how to reference 10micron... I'm assuming if I can see some of these flakes, that there must also be smaller pieces that I can't see.

I wonder if it is white ash, some of it is tough to get off, and it is almost like it has bonded to the rod. That's why I suspected this maybe being ceramic dust forming on the rod. Also since I see black lines on the rod, and that they burn brighter when on, I suspected the rod may be...

I know that the stuff around the heater cover is from the environment, and air...but directly on the rod? Wouldn't anything on the rod burn off? That's why I always let DBV burn for a few minutes before vaping. These flakes are white, and some wipe off, whereas some are more bonded to the rod...

I apologize, I didn't mean to insult the staff and the decisions you guys make. I didn't know that this thread should be in a different area, I would rather this discussion be moved than closed. Once discussions get closed, I can't help but feel suppressed. Moving on to the topic, I understand...

When I look at my DBV ceramic rod, when using a flash light, I can see little black lines that run up the rod, almost like cracks, but I can't tell if the surface is actually cracked because it feels smooth. When the heat cover is removed, these lines burn brighter than the rest of the rod...

I have been using my DBV daily for months now and I am noticing white flakes on the ceramic heater. I am certain after examining that the heater isn't cracked, but I can wipe the flakes off. Is this from being heated and cooled? These flakes are most likely being inhaled which is worrying me. I...

Can you buy 7th floor tubing in bulk? I wish there was a way to contact those guys. I have been sending emails for a while, with no response. I want to a new power cord on my DBV, cat chewed half way through the power cable.

I am still hesitant to put ISO in the tubing. I ran hot water through it and pinched the tubing to loosen the build up. I got most of it off but there are small specs still stuck. I blew all the beads out by simple exhaling through the tube. It's not perfectly clean, but it's close enough. I...

Would everyone agree that it's safe to soak the screen and glass wand in ISO? I usually use only hot water to clean the whip, but there is always residue left over. It never gets clean. I am hesitant to put anything other than water in the whip because I don't want soap and ISO getting stuck...

Thanks @Vitolo, I have seen your video and know your stance on the subject. However I would like to hear from some other members on this. I usually soak my screen and glass wand in ISO, is that what most people do? I am clueless on the best way to clean the whip, I have used only water in the...
