hi everybody Im ghosting this forum for a while now,and i would like to say thanks to all of you for sharing your knowledge here. So i have build a 18cm / 7inch/ double bell, batch box system for a friend of mine ,which i would like to share with you.How you can see from pics, this stove has the fire chamber located in a hallway and the bell is located in a wall dividing two other rooms.Really nice set up i would say.Most of the bell walls been build out of Magnesium brick which have a hight heat conductivity.For part of the bell we have used fire brick.So the proportions of fire chamber are 25cm /9.84"/ wide,37cm/14.56"/height ,and 50.o5 /19.7"/deep.The heat riser is 1m tall /39.37"/ and insulated with fire wool 2.5cm/1"/thick.The ISA of two bells above each other is 7m square /75.34 square foot/ .The chimney is around 6m /19.68 foot/ tall and 35cm x 35cm /13.77" x 13.77"/ old brick chimney ,not perfect but it works quite well. The whole stove are single skin and will be covered with clay plaster So thx again for your valuable knowledge and looking forward your comments. Radek Attachments:

Best conditions, brick walls all around. You insulate this house outside with straw bales , do the roof properly and you have the loveliest of warm homes  |

hi and thx for the comments .Here is a few pictures taken during the build.I have one question , what kind of gizmo you guys are using to measure the temp of the gases inside a bell. I do have laser thermometer up to 900C but it measures only surface temperatures.Thanks again Radek

I have one question , what kind of gizmo you guys are using to measure the temp of the gases inside a bell. I am using a digital two-channel thermometer. This device is capable of measuring 1370 C (2500 F) and is made to use a thermocouple, a thread that goes inside the bell and is sensoring the temperature with the tip of the thread only. Let's see, a large company such as Conrad should sell these. Yes, here it is, I do use a Voltcraft K102 together with this 1000 C (1830 F) thermocouple.

I have got some pictures of this stove finished by owner.There is 3cm /1 1/4 "/ of clay sand plaster with some custom made tiles .There is one quite strange thing.The green plaster was a mix of blue and yellow pigment and when the stoves are hot the green is changing its shade/we guess its the yellow pigment/and when the stoves cool it goes back to same shade of green.The dark red plaster around the fire chamber is home made Tadelack/marocan plaster/.

Radek, did you make the lime??
Otherwise Robert, Tadelact isn't too difficult to do, it takes a LOT of work and careful timing.

so here is the mix for my home made Tadelack.I do call it home made because around here you can get premix Tadelack material whith is quite pricey,but even for this home made mix you will need material made by company Baumit,im sure you can get it in Poland Robert.It is called Baumit Trassit plus and its a hydraulic lime of some kind.Than you will need ground Dolomit Lime rock,not hard to get in building supply or a nursary-garden store.This dolomit lime rock is in the mix instead of ground marble and if you wanna spend more money for the genuine ground marble no problem and the Tadelack shell will be propabuly harder.Next part in this mix is clay slip whitch you have to take thru fine strainer. And it all goes like this - 1.7kg of very fine sand,1.5kg of Dolomit Lime Rock or marble,1.5 kg of Baumit Trassit plus,0.5 kg of fine clay slip,1150 L of water,and pigment of you choice up to 10 percent of weight of all the ingredieces.Sorry Donkey its all in kilos. This mix is much much cheaper the original but the work which go in to put it on the wall is same as with the original mix.Whats really important is preparation of the base layer.It MUST NOT suck water otherwise the Tadelack mix will harden on you too fast and you will not have time to polish it.And how Donkey sad timing and a lot of work.
