Materials list help please PvdB

Later this summer, I’m going to be building a batch box rocket mass heater. I have all the CDs. I have a book.
I am trying to get ahead of these crazy price increases that are coming.
I need a materials list for a refractory supplier.
If I were building a J tube, it would be an 8 inch.

Can anyone help me put a materials list together?
I’ll be ordering from HWI in Charlotte, North Carolina.
Thanks in advance!

Hi Ty
Always a good idea to gather your materials ahead of time.
And buying now, rather than later, will save you some bucks for sure.

To help you with the materials, you need a definitive plan for what you will build.
A first-generation 6" Batchbox is quite different than an 8" J-Tube.
Are you thinking of a piped mass? Or perhaps a stratification bell?
What material do you want to work with?
Are you hoping to build as cheaply as possible? Or do you want a beautiful work of art?

You mentioned having a book; I assume it is the RMH builders' guide from Ernie & Erica, an excellent start to learning about RMHs, particularly J-Tubes.
You won't learn about Batchboxes or stratification chambers from it, though.
I offer a book on building the first generation Batchboxes, either as a hard copy or a PDF file

Let us know what your plans are.
