How to build a high Pizza-and bread- Easy oven from- Avoid using expensive refractory bricks. To get it heated as quickly as possible, get the most out of the fuel and use the basic tools. Make the damn pizza! Material list: recycled bricks about 100 I got my pottery from a local pottery equipment supplier who delivered it to the door. 4x100 liter Vermiculite stone bag- Also known as Pearl Rock Available from construction suppliers. 20x25 kg bags of concrete mixture 2x25 kg bags of concrete mixture 4x25 kg bags of mortar mixture 10x65mm- Thick steel bars- Concrete lines of 1x4 Wood for base formwork- Foundation 1 core builder ruins for recycling chimneys or similar ( EBay can help you) Fine strips salvaged from wooden venetian blinds (from IKEA! ) Long branches or long branches of oven dome wallpaper pastenewspapersods. . . Required Tools: Spirit level brick laying trowelplaster\'s floatSpadeMixing BucketPower drillPlaster hybrid impellerNice-to- Tools: Angle Grinder with masonry disc air compressor and pneumatic chisel. Working principle this oven works according to the principle of convection: the rear of the oven is on fire. It is supplied by cold air flowing along the lower half of the cavity. Hot air and smoke rise to the top of the dome and then discharge through the chimney along the upper half of the cavity. The hot air in the dome will radiate the heat back to the ground and any pizza that may hinder its development. . . . The top of the pizza is taken care of by it. The bottom layer of the oven is a material of high heat quality ( Thick clay tiles in our case) This is heated by the radiation of the dome and the heat conduction of the fire. A porous clay- The base material like Terracotta Warriors is ideal as it can temporarily absorb moisture from the pizza base, which helps to give you a crispy pizza base. After all, we are going to make the right pizza here instead of the thick and damp stuff that multinational companies offer. The fire starts at the front of the oven and when it is on fire it is pushed to the back. Fire may die temporarily due to lack of oxygen, but the convection process starts working in a few seconds and it grows again. The secret to keeping fire is to feed it a small amount of wood on a regular basis, preferably with long tongs, so you can put the wood on the burning ashes. You can test the convection process by dropping a few drops of water at the bottom of the oven: the resulting steam should go into the oven in the direction of fire, unlike what you normally expect. There is no hard rule to determine when the oven is hot enough. All I know is that when it\'s hotter than the highest temperature set by my home oven, it\'s ready to use. I also measured the exhaust temperature on the chimney when it was over 300 degrees Celsius ( Because that\'s what my temperature measuring device is) And then I know we\'re ready and the heat inside is far more than that. When the oven is ready, the cooking surface needs to be prepared by sweeping any ashes into the fire or sweeping out from the entrance with a natural bristle broom soaked in water. Then use a wet floor mop to pick up the remaining ashes from the cooking surface. For the same effect, you can also wrap the broom with a wet rag. You are ready to bake pizza. Some design of bread The oven usually has a thick inner layer made of solid, heat Fixed materials (i. e. High quality) This will keep the heat around 3 hours. The idea is that you make a fire inside, let it heat, then scrape out the remaining fire, put the dough in, close the door and let the bread bake. On the other hand, there is a fire burning in the pizza oven -- Or at least a glowing fire inside. Grilled Pizza on one side. It doesn\'t need hot capacitors like bread Oven, but much hotter. Both methods require good heat. Resistant to insulator. This design meets the needs of the pizza baker and the bread baker as it has an internal material layer with high heat and the heat around it Resistant to insulation. The better the insulation, the less heat you get so you can get the best energy from the fuel. The design outside the oven consists of three layers, each with different functions: 1. Inner layer: Mixed sand clay. This is a refractory material. e. It can withstand high temperatures. It is also crisp and needs layers outside to protect. This layer has a high heat capacity and therefore helps to spread heat evenly and radiate the heat back to the center of the oven. About 3 cm thick. 2. In the middle, the insulation layer. This layer must be insulated and can also be used as an insulator. The choice of materials is vermiculite (a. k. a. \"Perlite\") Glue with clay. About 10 cm thick. The layer also provides the first structural strength for the design. 3. Outter shell. Because every bit of insulation helps, this layer is also made of vermiculite stone, however, it is bonded with cement, which makes the shell hard. Since it is not too hot on this layer, it is acceptable to use cement because it will peel off and loose at high temperatures. 4. Weather- Moisture-proof layer: a layer of external cement keeps the worst moisture when it rains, but it continues to dry as the clay ages. For decorative effects, people can also lay tiles outside. The interior height of the entrance must be 63. 9% of the height of the dome\'s highest point. Who and how this is calculated is still a mystery to me. A chimney that provides good ventilation is needed to help absorb hot air and smoke from the oven, so according to the rule of thumb, the height of the chimney should be at least the height of the inner dome. Academic, engineer and other excellent math notes- Type of inspiration: I did not do formal calculations, although I have studied thermodynamics and structural engineering courses in college. Unfortunately, the beer was more interesting at the time. After a year of use, the structural design is well maintained. This oven is also unlikely to be hot enough for low fire Temperature clay potteryI have tried. Make a wooden frame of oven base size. This size mainly depends on the length, width and quantity of the concrete crossing you pass through the base. This one is 1 m wide. 6m deep. Collect as many architectural ruins as possible (a. k. a. \"hard-core\") When you need it, dig a hole deep enough to support the wooden rack and swallow all the rubble. Make sure it\'s horizontal, knock down any prominent part and press it all down. 2x25 kg bags of concrete mixture ( Composed of cement, sand aggregate) Pour water on the hard top Core until level with wooden racks. Roughly lay out the concrete and then smooth it with a plastering float. Once the base is set up, you can start building on the base. I decided to keep the pizza oven at a lower level so I could see the oven as I sat down. Therefore, the level of wood storage is about 1/2 high. The arches on the storage box and oven look good and keep it simple so make a half Round front in 3/4 plywood for wood storage and oven entry. Finally, the former is also used to create doors for wood storage boxes and ovens using routers. The nail-and-string- Pencil skills are good in painting semi-finals. circle, BTW. If you \'d rather build a toilet with your foundation, it\'s not too late to change your mind under coercion. Otherwise, continue to build a pizza oven if you manage to keep your wife quiet! Build brick lessons using recycled bricks and standard mortar mixes from DIY stores. Before committing, test the spacing of the bricks around the arch. Use a lot of mortar for this drill bit The extra part can be taken out for the level course. Continue to check the vertical and horizontal plumbness of the mental level. It\'s just a pizza oven and the error doesn\'t affect the final functionality at all, but you can also make it look professional. . . Because my pizza oven was built in a small mound, I created a rough wet environment Some proofing barriers from the left On the packaging plastic, then backfill with soil, and then trim off the excess plastic. Finally, use the mortar to top the last stadium to create a level for laying the crossing beam. Let the mortar set before continuing. This is the least complicated step, but it is also the most exhausting one, because the crossing beam is about 20 kg m each and needs to be moved around to fit the platform as perfectly as possible. I only got 110mm- Thick, but 65mm. The thick overbeams are just as good, and the floor is lighter and cheaper! You should relax now and have a barbecue. British, with venison burger (\"Bambi-burgers\") Sausage in Lincoln County, ribs with questionable red food color in the marinade and delicious ol\' plain Porkers. A dam will be built first and will maintain a lower thermal insulation performance. I used decorative bricks. Then build the second arch. But the difference is that it needs a cornerstone with a big hole, where the chimney rests. The final cornerstone is composed of two sandstone ( Salvaged from a mountain and stone in my garden) I use a pneumatic chisel to form a slot in one of them to form a hole. There are a lot of accessories and more mortar to make it look decent. I also decorated the front- Facing keystone with a year of Longing Date, use my pneumatic chisel and cut lines with a craft knife. It turns out that the sandstone can be carved well with a strong craft knife, but don\'t expect to use the blade on anything later! Install the chimney once the arch and cornerstone are set. I used 4\"- A diameter clay sewage pipe to obtain a good air flow column where a large Victorian decorative chimney will be installed later. The bottom insulation layer is made of a mixture of cement, water and bentonite. Make a bucket first- Install the cement paste and fold it gently in the vermiculite stone. Gypsum mixing impeller is very convenient to make slurry here and a lot of slurry needs to be made, so continue to invest in this cheap tool. ( This is also a great tool to mix a lot of pancake batter for country markets). Prepare the vermiculite mixture and sprinkle it on the dam Surface, and use the floating of gypsum board to make it smooth. Please note that in the last photo, the vermiculite stone surface is covered with a mixture of clay and sharp sand This is a mistake! It was broken to the point where it was completely useless. It turns out that the best baking surfaces are huge clay tiles. After a few steps, more information about this. So-is this oven- Called the basket method The former is not made of materials using traditional baskets, but by left- Above the slats of Ikea curtains. It takes about 30 of these slats. You can use any other curved stick: Tan, Willow, Palm, etc, instead of Batten. Start with a base circle 20 cm smaller in diameter than the final outer width of the oven. Connect the vertical slats to the circle to form a dome. A similar technique is then used to form the oven entrance. This is probably the easiest step, so it doesn\'t take much explanation, but see the animated picture for more details if you\'re stuck. Install the oven on the base, step back and imagine the ultimate beauty of what you\'re about to make! Well, sort of. Confuse some wallpaper. Cheat like me and use the impeller on the drill bit. Paint a paste in front of the dome and put down the first layer of newspaper. Paint the paper in this way and add a few more layers of newspaper. You should have enough layers of paper to prevent the sand/clay mixture from falling off the gap in front of the oven. Use at least 4 layers of newspaper and let the newspaper dry before proceeding to the next step. The inner layer of the pizza oven needs to be made of materials that are heat resistant and can maintain a lot of heat (i. e. High thermal/thermal capacity) It is also possible to conduct heat in order to evenly distribute and radiate the heat around the oven, avoiding hot spots. In other words, it is a bad idea to make the inside of the oven with insulation. However, we also do not want to escape from the surface of the oven, so this layer needs to be protected by a heat insulation layer mixed with clay and bentonite. Make the thermal mass layer mix again, mix the sharp sand and clay in a ratio of 80% to 20%. You need about 4 barrels of mixture in total. Apply the hot mass layer on the paper paste Case with 1 Your mixture is inch thick. Ensure the thickness of the layer is uniform. Roughly score the surface so that the next layer will adhere better. Let it bask in the sun for a few days. Like they are on me, cracks may appear. Simply fill the cracks with more sand/clay mixture, at the top of the layer with a thickness of less than 1 inch, and then let it dry again. It is important that this layer is as sound as possible as this is pizza Facing the surface, you don\'t want something in the food. Heat insulation needs to be heated- Resistant, need to be made of refractory and must be molded on the existing shape of the dome. We use a liquid mixture of clay and bentonite (a. k. a. Perlite). Clay paste with 12. 5 kg pieces of clay and 5 liters of water, cut it into small pieces with a shovel. Add a bunch of sharp sand to it to help chop and prevent it from sticking to the shovel annoying. Leave clay for a while to absorb more water. Then use the impeller on the drill bit to turn it into a brilliant gloop. Should be the consistency of double-thick cream. Gently fold with 50 liters of vermiculite stone (half of a 100-liter bag) Enter the slurry in such a way that the bentonite is completely covered by the slurry but not compressed It\'s kind of like folding eggs- It\'s actually turning white into a souffle mixture. In order to make enough insulating mixture, you need to repeat these 5 to 6 times, or if you have a mixing container large enough and feel brave, please do it at once. Place a 5 cm tall mound on the outside of the dome as a guide to thickness. Now use your hand and place the mixture of clay and bentonite on the dome. This mixture has amazing molding and elasticity. If it\'s too hard, wet it with some water. In any case, all this will eventually disappear. Be careful, however, not to press it too tightly, otherwise you will squeeze all the air out of vermiculite, which will cause its insulation to loosen. Compression is inevitable. Smooth the dome with the float of your hand or the plastering worker. More fun with your hands! When using a float, remember to always move only toward the top, just like you paint a real wall. All in all, you should have a total wall thickness now Including the clay layer belowof about 8cm. Again, let it bask in the sun for a few days. If there is a chance of rain, cover it with plastic sheets- It will still dry well below. It\'s not that serious. if at all - When it dries, it acts as a clay layer below, because the vermiculite stone is made of a number of clouds Like a substance that allows internal sliding. But there will be some cracks. Fill them with some left On clay, so, you \'ve been waiting for the oven to dry as much as you can, right? Because if you don\'t, if you go ahead with the next step, you have the potential to disrupt your hard work: just like everything made of refractory, first of all, they need to be lightly lit with a small fire, then ignite as the size increases over time until the material is stable. Because we know very little about the materials we make with sand, clay and bentonite, standing on the cautious side, it is safer to \"run the oven\" on many small fires before using the oven properly. The first ignition will consume the wooden fire inside, so pile a small pile of fire in the fire, and start the ignition with a spray lamp. In my case, the oven was built with a Venetian blind plate and was quickly ignited. I burned the fire in it for about 2 minutes and it ended. Feel outside the oven and look for any hot spots. Pay attention to them so that they can be fixed later with more bentonite/clay mixture, but ideally ( It\'s amazing! ) It should be very cool outside the oven. Let the oven cool for a day and sweep away the Ashes. You can see in the picture that the original baking face is shrinking and curling -- We will solve this problem in the next step. The baking surface is made of ceramic tiles 3/4 thick. This is heat resistant and easy to use. They also absorb a little bit, which creates a clearer pizza base. Usually, these tiles need to be replaced over time, so it is a good idea to lay them only after the dome is fully built. Like the evil witch from hnsel & Gretel, put your head in the oven for measurements. Use fret saw to cut Terracotta Warriors ( The blade will not last for a long time, but the cutting speed is fast) Shape it with a masonary file. Put them on a clay mud bed for comfort. I used a tea- The light emitted while working in the darkness of the oven. The shell is a standard building mortar (cement & sand) On the matrix of chicken nets About 1/2 thick. If you do not use chicken mesh reinforcement, then you will soon have small cracks in the Shell as shown in the figure. For some decoration, you can use ceramic mosaic tiles to tile the shell. I found a Victorian style chimney on eBay and I installed it on the existing sewer There are more pipe piles of mortar. I filled the gap between the two pipes with the left This way the outer tube will not be too hot. A standard chimney cover and a rotating wooden pile complete the chimney. In order to experience a happy pizza making experience, you will need to make or purchase the following tools :- The tool to insert the pizza into the oven and remove it. I made a pizza from oak tree. I also used it to scoop cold ash from the back of the oven. - Brush the Ashes on the baking surface to the brush on one side. This is a natural fiber brush mounted on an oak tree. - A handle errands pizza and push the burning afterfire to the small spoon behind ovenAlso also make a door that can be comfortably placed on the oven entrance. Use the shape in front of the original arch and do some insulation on the fire Multiple layers of alu on the side-foil. I decorated the door with some carved teutonic witt: \"Hot Heta \"(An old- German woman\'s name, Hert is the German word for the oven) And \"The road to hell \". Make Fire! Fire in the middle of the oven, if burning, until you have most of the remaining fire. Experience and experiments will tell you how much wood you use. Push the remaining fire behind the oven. If the residual fire appears dead, obtain convection current by blowing along the baking surface of the oven The fire should burn again. The temperature of the exhaust gas should exceed 300 °c. Occasionally add some wood to the back of the oven to keep the heat. Open the surface of the baking tray with moisture from the brush tool and brush the remaining ashes to the back. Wrap a wet rag around the brush tool and finish the baking surface. Baked noodles should be hot now, ready to bake pizza! Make Pizza! A truly thin- The crust pizza in the oven will take more than two minutes. Unless you have mastered the processing of floppy pizza bases with a pizza lifter, you should practice and try the pizza you purchased first. For better control, make a pizza at a time, no matter how many hungry people are eating a slice. Put the pizza in the middle of the oven, turn the pizza around and bake it evenly. Cook other materials using the oven\'s insulated door, which will become a suitable oven, using the residual heat of the remaining mild inner layer. - I slowed down the best Christmas turkey. Cook in the pizza oven for a night and then bake in the grill. It\'s all winter! - You can make amazing slowcooked stews -ox- I like stewed tail best. - Duck candy The slower cooking, the better. - Chicken and grilled vegetablesBake bread -varied success. . .
