#101728 L&l Easy18-3 E-2 Error

Posted by neilestrick on Yesterday, 03:50 PM

I guess I will order some more next week then, cause mine are starting to lay over in some places a lot. Thanks for the great advice from everyone. 

 

Put a  meter on them. Your manual should show what the factory resistance is. I've seen some ugly elements that were still functional. If you can get 10 more firings out of them, do it.




#100862 New Kiln Wash Flakes Off

Posted by neilestrick on 28 January 2016 - 08:13 PM

Bad kiln wash. It's probably got too much clay in it, which is causing it to shrink too much and fall off. Here's what I use:

 

3 scoops alumina hydrate

3 scoops flint

1 scoop kaolin

 

If it settles out too much, add another scoop of kaolin.




#100652 Crumbling Firebrick Needs Repair?

Posted by neilestrick on 25 January 2016 - 02:49 PM

The broken bricks should be replaced. There's no seal there any more. You may have to replace the elements, too, depending on how nicely they come out. Old elements can be very brittle.

 

If this is constructed like many square top loaders, it's going to be a nightmare. You'll need to remove the top frame, which may be rusted on. The bricks themselves may be full wall modules, not individual bricks, in which case you either have to replace the entire wall, or cut out and fill in with individual bricks, which is incredibly tedious and messy. Stock Cress bricks may have grooves that line up if you go that route. The bricks is probably backed up by some sort of fiber board, which may also be crumbling. You won't know until you get into it. Fair warning, you're opening up a potential can of worms. Personally, I will not replace bricks in these types of kilns. It's just not worth it for my customers to pay for the amount of labor needed to do it right, and often I just can't get the kiln taken apart anyway since they rust out so badly around the top edge.

 

There's no such thing as a free kiln.  ;)




#100267 Cooking Pizza In A Pottery Kiln, Toxicity ?

Posted by neilestrick on 20 January 2016 - 03:59 PM

When Orton comes out with a Pizza Cone, then I will cook one. I prefer my pizza not to be under-fired.

We used to joke about room temperature cones- made of butter and ice.

The only way to be sure it's safe, is to send the pizza to a certified lab for testing.

 

HA! Love it!

So just so we're clear, I don't have any hesitation in saying the OP is having a laugh at our expense.  Mark Dally, the OP--Crunchypop, is a potter with a lot of experience (like, graduated from art school with an MA in ceramic design the year before I was born kind of experience).  He knows better than this.  He fires lustres and brightly coloured wares all the time.  From what I've seen of him on social media, he's got a bit of an impish sense of humour, too.

 

At least, I hope for the sake of his health that he knows better after 34 years plus of working with ceramics....

 

 

If it is a joke, it's irresponsible of him to post something like that on the 'net, where folks who don't have his level of experience might think it's okay.

Posted by neilestrick on 19 January 2016 - 08:02 PM

Really bad idea. It's not just the dust, but the fumes from all the stuff that's been burning out of your clay and glazes, including metals. When the kiln heats up those things come out and can get into your food. Would you eat food off your glazing table? No. So don't eat food from your kiln either. Food and industrial processes don't go together.




#99999 Reliable Cone 6 Temmoku Glaze Recipe Oxidation

Posted by neilestrick on 17 January 2016 - 05:34 PM

Manual kiln I have lol...

 

Our plans as of now are to get a smaller kiln to test with and then get into making our own glazes... Our bigger kiln will be a bisque kiln or maybe convert it to gas... we just got a price hike from our electric company... UGH

 

If you run tests in a small kiln but fire work in a larger kiln, you will not get the same results. Little test kilns cool really fast. IF you plan to go that route, I highly recommend getting a digital controller on both kilns so you can do the same cooling cycle on both kilns. At the very least you'll want a digital controller to control the cooling on the small kiln to mimic the cooling cycle in the large kiln, even if you don't have a controller on the large one.




#99871 Is A Square Cross Draft Kiln More Efficient?

Posted by neilestrick on 16 January 2016 - 11:45 AM

I would not use the soft brick stacked on their sides. They won't stay put. When using both types of brick you need to run a course that ties them together every 5-7 rows. I think you can do a 4.5" soft brick inner row with a 4" hard brick outer row and be fine. You're only half an inch short of normal there. Fiber is a mess. Avoid it if you can.

 

I would go with Marcia's design if you need both burners and want to use a single shelf. If you don't have enough bricks for that, go with bringing the burners in on the same side, opposite the flue, along the long side of the shelf.




#99775 Good Wood Fired Clay Over The Counter?

Posted by neilestrick on 15 January 2016 - 01:08 PM

sorry- which troy body do they have? I think they have 437 and 621 . 

 

He said the porcelain one, which means the 437.




#99768 Good Wood Fired Clay Over The Counter?

Posted by neilestrick on 15 January 2016 - 12:33 PM

Rebekah- I was in Evanston today and they said they stock the 508 woodfire body, and usually have a couple boxes of the Troy woodfire, too. If you decid you want some let me know and I can get it to my shop to save you some drive time.

Yup, you did it right. It's only the last 200 degrees that really matter.




#99695 Is A Square Cross Draft Kiln More Efficient?

Posted by neilestrick on 14 January 2016 - 09:47 PM

So, a layout like this image- burners on left, long shelf, exit flue on right? Would do it the other way- turn the shelf so the burners are coming in along the long side of the shelf, leave 9" or more for firebox and bag wall.

#99436 How Can I Convert A Large 3 Phase Kiln To Single Phase?

Posted by neilestrick on 12 January 2016 - 08:56 PM

They demand lower operating costs and pay for the power grid lines to bring in 3 phase. 

 

 

3 phase kilns do not cost any less to operate. Firing costs will be the same regardless of phase. Watts are what heat kilns, not amps, and watts are what you pay for. Regardless of the amperage, the watts will be the same.




#99434 How Can I Convert A Large 3 Phase Kiln To Single Phase?

Posted by neilestrick on 12 January 2016 - 08:52 PM

If it's pulling 37.5 at 3 phase, it will pull about 65 amps at single phase, which will require an 80 amp breaker. Depending on how it's built and local codes, that could mean a major rewiring, including fused branches inside the control box, bigger relays, etc. You'll need to check with the manufacturer. They will be able to tell you what's needed.
