Alternative to fire clay

Dear Matt
Thanks for your wonderful stove
We live in Colombia and here you can not get fireclay. What other materials can be used to glue the bricks? Can you use normal cement?
In a video you mentioned that you can make an oven on the right side of the stove, what elements and considerations should be taken into account for its construction? We can not find this element in the plans we buy.
Can the stove be built with benches on both sides ?, What should be considered for its proper functioning?

Thank you very much in advance for your help.

You can use normal clay to glue the firebricks. Mixed with sand, with grog (old bricks crushed into sand and powder) with pozzolan, You can use corundum sand.

You can replace the clay with ciment fondu. Don't know the translation.

Which stove are you talking about?

Do you have any clay in your subsoil? You would be surprised at how well local clay works as a fireclay substitute. My subsoil in my own backyard has amazing clay that would definitely pass as fire clay. It has lots of alumina and very little iron. I have made allot clay using the water extraction method from the sub soil in my own back yard. You can also check out construction sites and riverbanks, etc.....
