Do I NEED a bead door?

Hi everyone,

I've been looking into buying a kiln that I can use for several things (glass, ceramics PMC etc).  I'd whittled it down to the Paragon Caldera, with the option of buying a bead collar to go onto it.  This would mean that I would be able to work without the collar and fire up to the ceramic temps I need, and with the collar when I'm doing beads. 

Now I've been told that this isn't possible as you could detach it whilst the kiln's on and this would be dangerous.  So this now means I would need to get it (a) without the bead collar (no bead door, but hot enough for ceramics), (b) with the bead collar permanently attached (not really hot enough for ceramics, but quite big) or (c) get something else - the Paragon SC2 was suggested, looks good and has good reviews (again not really hot enough for ceramics, but with a bead door.  It's much smaller than the Caldera + bead collar, but less expensive too).

Does anyone have any experience of the kilns above or advice?  I was thinking that I would just go with the basic Caldera, but worried that I might get frustrated about not having the door?

Sorry for the waffle and thanks for the advice in advance!

With a bead door you're only opening a small door at the front to put the beads in, so there's presumably less hot air leakage and the temperature remains stable so presumably you're less likely to get cracked beads. Though I'm not an expert and I don't know how much the temperature fluctuates when the door is opened. Also if it's a lift up lid type of door once again you're going to get more hot air escaping when you open it.

But it all depends on what you are going to primarily use it for. If you definately need to do ceramic stuff and cannot do that with a bead door and that's the kiln's primary purpose then you can't have one. But if beads are the prime purpose then it's awfully handy. Course you could make do without and batch anneal.

Julia, I thought it was a case of simply unclipping the bead collar when you didn't need it - when the kiln is switch off of course.

You can buy the bead collar separately, so it must work in this way?  Otherwise, what would be the point of the collar on its own?


When I had mine delivered, the base wasn't even permanently clipped to the body, it came out the box not attached anyway....


Yes, thinking about it, you could take it apart whilst its switched on, so the relay in the lid that isolates the electricity when that opens (Lee, Kilncare's bone of contention!) is pretty defunct!


Ask Shelley (Good Monkey) - I know she has a Caldera, and as she bought it for annealing, I assume she had a bead collar version.



Incidentally, I believe the reason that the bead collar affects the temperature is not because of the door opening, I think its because the extra height prevents the kiln from going up so high, but I could be wrong there.

I used a bead collar on a Caldera for ages - it was really good. I don't know how I could have annealled beads as I went along without one  ;D

My advice would be that if you have made up your mind to get a Caldera and you want to anneal as you go - get a bead collar.

Thanks Helen, Dawn and Hazel,

I do really want to be able to do ceramics in the kiln - it's my first love and what I have been making my jewellery using for years.  Beading is new to me and I can't really gage yet if it is going to be a long term thing (though certainly looking promising!) so ceramics really needs to be a consideration.  I haven't found cooling the beads in my fibre blanket difficult so I think I'd be fine with batch annealing if it means I can do ceramics too.  It is a shame though, the bead door would have been useful!

I've found a site that supply the basic Caldera sealed together and they refuse to sell the bead collar with it unless it is also secured on.  So if you look inside it at all (I suppose by lifting the lid) it will switch off.  I can understand where they're coming from.  I've looked elsewhere, but they are much more expensive.

I guess I'm leaning towards the basic Caldera!?  Grrrr...there's always something else to think about whenever I've just made up my mind!

Why not get the Caldera you want, which you can batch anneal in quite happily. If you want to start garaging later on, you can just get a little beadcube for that. It's small and neat enough not to feel like you're losing too much space.

Where have you found it like that, Julia, and at what price?

What's "interesting" about this idea, and this discussion has been had before.... so, they sell it, with bead collar sealed on.  Fair enough, sensible.  Switches off when opening lid, sensible.

So, clearly they're thinking that the average consumer is utterly dim enough to try and separate that kiln body from its bead collar, whilst it is still switched on..... (no, I know, that's not what MOST people are likely to do) - same dim-wit though, might decide to poke a mandrel up at and angle and into the exposed elements which remain on when you open the bead door..... hmm, wonder if they've thought of that?

Edited to add:

Sorry, I know that sounds a bit erm, I dunno, harsh, against the seller who is trying to cover all safety aspects.

An Julia, sorry, I know you probably don't want to say who the seller is on here, cos that would be being negative about them, and that's not good form.  Did they also say they would supply with the base permanently fixed on, too?  As far as I can tell, this means them actually modifying the kiln somehow, like welding it together?

Caw :o  Didn't know I was taking my life in my hands everytime I use my caldera with the bead collar ???  Must remember not to try to lift the top off while I'm doing it ::),  I think I might notice though as it would be a bit warm ::)

 ;D  I did wonder if I was being rather overly cautious?? 

The man never did say that I would separate it while it was actually on, just that he wasn't happy to sell one that you could do that with (fair enough I think).  He also did say he could get one made up with the bead collar on already if I wanted it, but permantly fixed.  I don't think he ever said how the basic one was joined - if it came like that?  I did feel that I was being a little annoying, making him clarify everything, but he answered all my questions - plus at the end of the day he doesn't have to sell anything he isn't comfortable with. 

I can always go somewhere else for a basic one (though I've only found one other place so far?  Where did those of you who have caldera kilns get yours?). And then try it for a bit and get a bead collar at a later date if it annoys me.

Thanks for your thoughts  Julia x

And there was an ebay shop, but can't remember name.

I am sure there's others too

The problem with relying on batch annealing is that if you get into making slightly larger beads, they don't survive the Vermiculite, fibre blanket phase.

I have a caldera with bead collar. The kiln "stacks" together, and has clips.  When you want to fuse, you remove the collar.  I don't know what your contact is talking about when he says permanently fixed...  ???

I got mine from in the US wired for the UK and with the cut off safety switch to meet UK regulations  :) But Robin at Paragon Kilns has always been helpful.
