Discontinued Thermovape Cera

I think you should try adjusting your draw speed. That was my biggest hangup when I was starting out. Cera's intake holes are small, both in the body and at the bottom of the cart, and the obstructive filter in the mouthpiece adds restriction as well.

What this means is that what may at first seem like a light draw is actually pulling air through at a respectable velocity. That is, given a constant strength of pull, the velocity of the air moving through the device that you're drawing from will increase as the restriction is increased, because the same amount of air is now trying to enter a smaller space.

I became proficient with the MFLB prior to getting my Cera, so I thought I knew how my draw correlated to air speed in the vape. But the restriction in an MFLB is minimal in comparison, and I had instinctively associated that feeling of free flow with the resultant air speed. It turns out that you can (and should) lighten your draw and still end up with the heat moving in the cart like we want.

Once you have the pre-heat down (step one of OF's three step process), try drawing very very slowly, even a little more slowly than you're comfortable with, and do some test puffs. Slowly work your way up in draw speed while continuing to use occasional test puffs to gauge your progress.

Drawing more slowly than you're comfortable with is only intended to provide a low starting point for your tests, as I think most would be surprised how much heat can be delivered to the herb with what at first might seem like too light a draw.

What we're trying to avoid is pulling too strongly too early in the process, as you can actually manage to cool the coil down with an early hard pull.

Test puffs are important here because the ceramic mouthpiece does an outstanding job cooling the vapor (and perhaps maintaining a small particle size in the vapor), to the point where I find it very easy to pull vapor and not realize it. Test puffs in proper lighting will help you learn exactly what you and Cera are doing together.

Using a little glass bubbler mouthpiece on it can help you see what you're doing more directly, as a learning tool. Like training wheels? Also, shimmying up the mouthpiece to watch the effect that a hard draw has on the glow at the start while in the dark with a mirror (the glow shines through the cart walls) lets you witness firsthand how pulling hard at the start can cool the coil down.

Given that it's working to some extent for you, I think it's unlikely that anything is mechanically wrong with it. Your story is very familiar to me; I experienced precisely the same thing and also instinctively feared something was wrong with the device. I got it sorted out though, as can be seen in the video in my signature here!

@thegoo, Like nopartofme, I think your problem is technique related, not equipment related. One look at the glow of the core will sort that out for you anyway.

Like you I've had a bit of trouble with my Cera technique after coming from successful T1 technique (not there with you on the evolution - gave up on that one). I've had what you are describing with great flavour and no clouds. Only problem for me is that I don't get as medicated as with the T1. If I was getting medicated with great taste but no clouds, I'd say "bugger the clouds," and be happy with it.

If you really want clouds though, I'll give you my fail safe method. The taste goes down hill real fast with this method, but maybe you can gradually scale it back to a happy medium.

The first thing you need is a good pack. I find the Cera to be more pack sensitive than the T1. A good pack for me means making sure there are no spots air can go around the herb rather than through it. You also want to try to get a little restriction from the load, beyond that which comes from the device itself. This makes the biggest difference for me in getting clouds. You don't want too much resistance though, as it will cause one of two things: 1. The top of the load won't get fully vaped, or 2. The load will pack together and the air lift it up a bit and go around it, rather than through it.

There are a couple of different ways that people achieve a good pack, but I'll give you mine.

1. Grind your herb medium fine. You want it to be quite fine but also fluffy and springy. Having the herb stored at a moisture level of 58-62% helps with this. Boveda make 2 way humidity regulating packs. The 62% ones were made for the CVault containers. The 58% ones are made for the Rico reed company for long-term storage of clarinet/saxophone reeds. I think that 58% is better for vaping and 62% is better for smoking.

2. Pour your herb into the bowl, using a small container like the Jyarz containers you can find on this forum. This is trickier than the T1 because of the small, narrow bowl. I find I need to push the herb around at a couple of stages to insure all gaps are filled. I do this with my finger, being very careful to avoid packing down, or I use a toothpick. I fill until the herb domes up a little over the top lip. Others pack it flat with their finger, but I just let the cap do that for me when I push it down. How much you overfill is up to you, but the key is how much extra resistance you feel when you pull on it. You only want a little (if I don't overfill a little I don't really feel any difference from pulling on an empty cart).

3. Let the device heat up for 2 minutes. Do your step 2 slow pull for about 8 seconds, ramp your draw speed up for a couple seconds than pull quite hard for another 5-10 seconds. You will get a big cloud. Keep the switch latched on, and for the rest of your draws, just pull quite hard from the start of each draw as the whole load will be up to temp from the word go. Unfortunately, with this method, the flavour will start to go south even on the 2nd draw. The clouds are absolutely MASSIVE though, and keep coming for a surprisingly long time. You'll easily be able to beat the heat and get the bowl done quickly though. As I said, you will probably be able to come back from here to a happy medium. I personally find this happy medium to be far easier to achieve on the T1. The core gets to full glow on the T1 very quickly, so that makes step 1 easier. When you do step 2 on the T1 you can feel when it is time to go to step 3. This again makes it easier. I feel that the Cera LL would be easier to use if you could just leave the switch latch on and forget about step 1. I think I would need a lower powered core for this to work for me with the flavour duration I want.

Hope this helps.

One more thing. I often see pre-heat times of 30 seconds and more mentioned. I think that getting a lot of heat built up like that is useful when starting out, but it shouldn't be taken as gospel as to how long you need to wait. My personal rule of thumb is holding the cart itself from a cold start, activating power, and waiting for the cart to get warm. In my experience this happens in something like 10 to 15 seconds, and I have no trouble going from there.

This is dependant on battery type and state, though.

A good indication of weather your unit is working as designed is how long it takes to fire up. What I mean by this is how long does it take till you see the first glimmer of life through the holes in the bottom of the cart. When I got my unit in Feb and after I got a new switch it started out pretty quick but soon stretched out to 10-15 seconds before I would see the start of glow. Now after I had the strap replaced a few months ago I never NEVER get past 4 Mississippi maybe at the longest I got to 'ssippy but not 5. Of course this is purely the first hint of a glimmer but any longer and id say something may not be quite right.
Im with the hold the cart from cold camp when you feel warmth on the outside after 30 or so seconds start loading while keeping the power on and by the time your loaded with top on ur up to about 1 minute and should have plenty of heat built up to produce some nice vapour. And I agree with pull softer than you think to start with, when the power has been on for ages and its red hot you can give it a good ol honk but look out this has been known to kill men :smug:

Edit: @Vape head the EL cart is available I ordered one on the 10th they posted about 5 days later and according to tracking it went through the sorting office down here in Australia over the weekend so I'm hoping to get my hands on it tomorrow or the next day. I will let you all know what I think. As far as the mini your guess is as good as mine though im sure there was mention of this xmas but I think there isn't enough time now...

I do the same, i let the cart heat up empty until it starts getting close to uncomfortably warm on the outside then i load with a doob tube which works perfect. I load until its level with the top of the ceramic bowl, then kind of spread the load out evenly with my finger but dont pack it at all. Give it another 30 seconds or so to warm up then i go for it with a long really really slow inhale, i always get a fat hit first draw. It kind of sketches me out if TET said i shouldn't hold the power for more than 45 seconds because i don't let off the power from start to finish which is at least 5 mins. Well this is how I use my cera which might not be ideal for other people so dont destroy me for sharing my experience, this is just what i have found to give me nice clouds. I will say my cera has been going strong and has been my daily for the past 5-6 months so has definately been getting quite alot of use.

@YeeeBuddy, I don't think that there is any suggestion from TET that there is a problem holding down the switch for a long time. What they mean is that you shouldn't NEED to hold it down for more than 45 seconds.

TF

Agreed.

In the initial testing I did on the now closed threads I reported runs of 15 or more minutes straight. The unit is designed to 'take it', but there is no need to do so and it wastes battery and time and makes the unit hotter in use than it needs to be (the wasted battery power has to go somewhere......).

You'll also notice there is an official "simple technique" for new users that does exactly that? It's not 3 step based. You simply turn it on and start sipping and don't worry about the wasted energy (no THC is lost).
http://vaporpedia.com/wiki/ThermoVape_Cera#CLL_Usage

For our use the core saturates fairly early on under normal conditions (the coils themselves get 'full bright' as does the support rod under them, as bright as they ever get) and even though the rest of the unit get hotter, the core no longer does since Infrared Radiation is blowing heat off as fast as it happens (equilibrium). At the start all the heat made the metal hotter, as time went on less and less did and more heated 'other stuff' up, once saturated all the heat produced goes someplace else (makes the body hotter basically).

You gain nothing by heating any longer past this point, it's ready. Go to step 2. All you do is waste battery, make the Cera body hotter and harder to deal with and get bored waiting. But you can't make the coils and walls any hotter (IR is rattling all over in there), therefore you can't make the air hotter or get more heat to the load to make vapor (the original goal). It's saturated, as hot as it can get by design.

Your call.

There was @ThermoCarloTV too, haven't seen him in a while.
i know man, i was just joshing ;) thanks for the effort anyway!
agree that we haven't heard from any of them in quite awhile. not much after half the crew left

Depending on what mysteries the new EL cart holds, I think it could offer interesting possibilities in combination with Liquidizer's EJmix. I'm not sure if the increase in capacity would make up for the dilution in terms of how much actives the cart could hold, but the freight train power of the EO cart would be overkill for an oil virgin like myself anyhow...

I have an EL cart in my future regardless. I'm excited!

hey gang, here's a battery charger that will charge 4 18650 lion batteries at once, and does a very good job of it. it will also charge many other size batteries, and the 123 rechargeable cells for $18 and change at amazon (I paid $45 for mine at battery junction :
http://www.amazon.com/dp/B005UAI372/ref=pe_385040_30332200_pe_309540_26725410_item

I keep 3 fresh ones lined up ready to go at all times.

And for those quick wearing o-rings I suggest a tube of 100% silicone grease , available from radio shack, (will post online source at later date) -- I put an infinitesimal amount on the rings almost. every time I refill it, and it keeps it operating smoothly. :)

My cera will be here in about 2 1/2 hours, I'm very satisfied with the 2 day shipping. I feel like its christmas morning, I tried staying up all night, didn't work. And my tracking number starts with 420! I will update this post with my review shortly. UPDATE: OK WOW! This thing kicks ass I'm literally high off one hit. And it was a really small one. I haven't gone for any big hits yet but I just haven't let it fully warm because I'm trying to conserve.

hey nooby , we've heard all that boring stuff before! quit cluttering up the place with non essential information and your personal comments!
sheesh! I have important things to do!
and don't ask any dumb questions before you read the preceding 236 pages!

Absolutely, welcome to the fun.

Since the new guy can't really buy a round for the house, we've got a different plan here. One of the older guys will PM you a list of names, you'll notice Tedthehed's on it. Send a gram to the top name on the list, put your name at the bottom and send the new list of 8 names to five of your friends.......

Great Scott!
So my EO cart has black ceramic after boiling AND 2 iso soaks. What is the next step to try to get that back to white? It needs a serious cleaning because its just gross as hell at this point.

Getting a used, let alone abused, cart back to 'white as new' is not a feature as I understand it. It's quite normal to not even be able to see the glow of the heater when too much carbon gets burnt in the pores. With some concentrates this takes less than a gram. It's designed to continue to function, but not to look new again.

Sending it in is the next step IMO.

Ehhh I don't wanna send it in. I'm sure it works, I just want to make sure its as clean as its getting before I reload it. I'll give it one more boil and iso to be safe then its time to load.
