As another Lame Cherry exclusive in matter anti matter.
It seems every project I get involved with is one where I have to invent the wheel. I share these things as most of you have no idea the difference between mortar, concrete and cement.
The big issue with fire breathing stoves like I'm building is the buzz word of REFRACTORY, which most people blink at, and it just means it does not absorb heat, as concrete is supposedly different than cement, even though concrete has cement in it.
Cement is Portland Cement which is lime and then concrete is a product which sand gets added to the cement.
Heat cement is more bullshit in it has Perlite, Silica and Fire Clay. Most of the gomers online just add cement to perlite and they get this non absorbing heat mass.
I will get into glass jar sometime too which is a super high heating 3000 degree coating.
Of course in the brier patch none of these numb nuts know nothing about refractory cement, and why would they have perlite as more to the point why would they not order the shit in for a customer.....no they just stand around looking as stupid as they are.

Cement Recipe #1
What You Will Need:
●Portland cement (You can purchase a 94 lb. bag at yourlocal hardware store for less than $10.)
●Perlite (Can be purchased for $10 to $25.)
●Silica Sand (A 50 lb.bag costs less than $25.)
●Fire clay or Well drillers mud (A 50 lb. bag averages lessthan $10.)
The Formula1.5 parts Portland cement + 2 parts Perlite + 2 parts silica sand + 2 partsfire clayWhat to Do:Using the portions listed measurements listed above, mix the Portland cement, Perlite, and silica sand together thoroughly.Combine the mixture with 2 parts fire clay.Once the mix has the consistency of stiff cookie dough, pack it into the preformed form. You may need to add a little bit of water to get theright consistency.Allow it to dry for several days
This is the rest of the gumby recipes they were posting.
The first formula is the same as the third. These are the basic pizza oven burn chamber recipes. It makes a semi light weight concoction, which is not supposed to crack or absorb heat. These are not mason stove. The first formula will be good for 2500 degrees and so will the rest. That is more than should be enough for a wood stove.
Refractory Cement Recipe #2
This recipe is an excellent option if you can find ready made furnace cement. (Many home improvement stores do sell it in ½ gallon buckets for $12 to $20.)
What You Will Need:
- Furnace cement
- Perlite
- Water
What to Do:
-
Mix the ingredients together thoroughly using the above measurements. Be sure to stick to the formula. If you use more than 4 parts Perlite for each part of Furnace cement, the results will be weak. However, if you use less than 4 parts Perlite for each part of Furnace cement, it will take forever for it to seal.
-
When the Furnace cement and Perlite are combined, you will get a consistency that is very sticky to say the least. If you add around 2 cups of water per gallon of cement, it will be much easier to work with because it will have a consistency comparable to thin plaster.
-
Form your preferred shape and allow to completely dry.
Refractory Cement Recipe #3
What You Need:
- Pure Perlite Standard 2.0-5.0 mm
- Fire cement rated a minimum of 1400⁰F or higher. (Make sure it is at least 1800⁰F for brass.)
4 parts Perlite + 1 part fire cement
What to Do:
- Mix Perlite and Fire cement using the above measurements.
- Allow it to try for several days at room temperature. (68⁰F -72⁰F)
- Bake at 250⁰F for several hours until no steam or smoke is coming out of it. Allow it to cool completely.
- Repeat at a slightly higher temperature. Repeat this step until it is completely baked in.
I am becoming an expert in all of this and by the time I am done, I will be employing Don Trump jr. as my brain has expanded endlessly on these projects.
