In this Instructables guide I will teach you how to build an Adobe Oven! What you use this Adobe Oven for can vary! Me and the crew that built this structure plan to use it to cook human feces so that it can rid it of infectious diseases and then use it to fertilize different types of vegetation. Take a look at our Website for full information at http://poopgroop.weebly.com/
Other than that take a look at our instructables for a full detailed guide on how to make your very own Poop Adobe Oven!

Step 1: Get Your Supplies!
Get the following supplies to begin building you Poop Oven!
1: Wooden Planks (a LOT of planks required)
2: Clay (plenty of clay for plenty of adobe)
5: Multiple buckets
6: Hay (more than a couple handfuls)
7: Multiple tarps
8: Water Source (like a water hose of well)
9: Large flat ground (To have the base and the bricks harden with flat bottoms)
10: Lots of sun to dry and allow the bricks to harden easily
11: Nails and a Hammer/Screws and a drill
12: Hands (to mix the supplies to make adobe)
13: A flattening tool (a flat piece of wood, flat gardening shovel)
14: Piece of plywood for easy transportation of the base
15: Small wood plank pieces (to separate bricks in a frame)
16: Saw, table saw or chop box
17: People to help create adobe and build frames
18: Hands or feet to mix adobe
20: Store bought heat retention bricks (make sure to measure to exact size that you need)
21: Reflective material (windshield reflectors)
22: Glass sheet (big enough to cover the top to focus the sunlight)
23: Store bought hinges
With these supplies you can begin to create you Adobe Oven! It's best to have all items at your disposal before beginning to create your oven.
Step 2: Create Frames for the Base
It's best to have a stable base for your adobe oven but if you'd like, but you can also make it out of individual bricks as well but it would require them to be stuck together to help keep the warmth leaving from the cracks in between the imperfect bricks. Me and my partner just used four planks of perfect height and width, cut with a saw, and nailed them together with small stable nails.
Step 3: Create Adobe and Fill in the Base With a Tarp at the Bottom
To create adobe you require a lot of clay, a cup of sand and a pinch of hay. But for our base of 24x38 we require at least 2-3 handfuls of hay.
The first part is to place all the materials together then add plenty of water to make it look like wet mud but not enough that there are puddles of water. For the base we mixed the adobe in the tarp and my partner used his feet to mix it once mixed we attempted to even it out as much as possible to that when it dried it would not look like the dunes of a desert. After flattening it out we let it to dry for one week for safe precaution, in direct sunlight.
Step 4: Creating a Frame and Adobe for Bricks
Unlike the base it would be much better to build the walls out of bricks so that it can be easily moved if necessary. We required approximately 50 bricks to build all the walls and one brick the size of three, for the slot that will be used to pull out a tray with the feces. We built the frames out of wood and cut several dividers for the pieces.
Then me and my partner created adobe in a bucket to easily pour. He mixed the clay with his hands and poured it out slowly onto each individual brick frame. Make sure the frames and bricks stay in place while they dry. And dry them as you did the base, in clear view of the sun.
Step 5: Removing Bricks From the Frame
Begin removing the bricks slowly from their frame and make sure to be careful if the bricks aren't completely dry. Once you've begun removing the bricks begin placing them on the frame one by one in order. Try to make the bricks all the same size and attempt to measure their size so they fit equally into the frame to create the outer walls. If some bricks don't come out the correct size or break feel free to remake them, or you can as well make extra bricks.
Step 6: Placing Both Types of Bricks
For the inside we placed the store-bought heat retention clay bricks. Of course these have to fit inside of the adobe bricks so make sure to measure the bricks you buy and the space available to make sure that they match in size. Leave a space on a few bricks to make sure the pan you use will fit in between. Make sure to arrange the bricks evenly. In case of extra bricks make sure to remove them and place them to the side. There are four bricks on top of ours that are extra that are meant to be put off to the side. Just remember to place them evenly and make sure they fit tight enough. Try to leave as little cracks in between the bricks as possible, and if the bricks are uneven arrange them so they end up at almost the same height.
Step 7: Placing the Glass
Make sure to buy glass that fits your oven. Make sure to leave room to place things inside, and as we did have removable bricks to place material inside. If you can buy a metal tray that fits exactly (or close enough) to the open slot that is used to get inside the oven. If the bricks are uneven on the sides you can try to rearrange them to similar heights. We used three store bought bricks for the removable side because our adobe replacement didn't harden well enough, or really go well at all. Once you think it's well placed go ahead and go to the next step.
Step 8: Placing the Reflectors
The next step before placing anything in the oven is to place reflectors. We placed only two reflectors on two sides but feel free to cover all four. Angle the reflectors correctly so that they reflect the sun's rays into the oven or try to make the reflectors adjustable. We used car reflectors to manage the light, but anything you might find that reflects light well enough should work fine. Being able to adjust the reflectors freely should also be a priority so that at any time of day you can move them so they do not block the light, and during the night time you can fold the reflectors inward on top of the oven to use them as an insulator. We connected the reflectors to be adjustable using small hinges. We used super glue to keep the hinges to the glass and the reflectors to the hinges. We are temporarily using wood planks to hold up the reflectors.
Step 9: That's It!
Now you've completed your oven! Feel free to cook whatever you want whether that'ts feces or steak! Enjoy your Solar Oven courtesy of the Poop Groop
