We are about to build our first masonry stove and want to use clay mortar. We have much clay on our property and would like to use it. Does anyone know of a method to prepare a clay mortar and test it for suitability in a masonry stove build?
Thanks All
Josh and Maio

Josh :Congraulations on finding these forums and becoming a Fellow Member ! With over 33,000 Members Around the world you should be able

to come here 24/7 and talk to someone who wants to talk about what you want to talk about !

You need to learn for yourself HOW to test a Soil sample for its percent of Rocks and sand, clays, silt and organic matter, and then test a Sample

of clay for its suitability for Cob or clay slip ! Also you need to be able to make, test, and evaluate a series of clay and sand mixtures to " Prove ''

Their ability to bind into a durable and structural whole!

So- Besides Clay Slip. there is Insulating(-ish) Cob, Thermal Mass Cob for heat storage and transport, and Structural Cob !

None of this is rocket science - oh! Wait ! Yes it is !!! but a lot of dim bulbs like me have managed to grasp the basic ideas, with a good book to

back them up !

This is where I recommend that you goto and purchase a Copy of " The Hand-sculpted Home " By Ianto Evans Who

is the undisputed 'Father of the Rocket Mass Heater " _ You do have the 3rd Edition of his book Rocket Mass Heaters right ? Both of these

books ought to be in a Builders Library !

Get the Books, read the books, and come back here with your questions ! If there is a Masonry Stove in your future we will help you make it happen

For the Good of the Crafts ! Big AL Good Luck !

Thanks for the book ads allen, though I'm sure they are great, at this time I only want to know about clay mortar, and was hoping someone has done this and can give me a simple process to test and evaluate and mix clay mortar from local clay soil. Or a recipe? Otherwise Ill just start experimenting with 1/1 clay to sand and test a bunch of bricks…in a fire…i guess….
I agree. Here's the link:
