Can you use this firebrick for a propane forge?

[LearningToForge]

Just looking in to propane forges, maybe a "micro" forge. The idea is for making knives or heat treating or whatever you do with a forge and stock removal. Are these suitable for a propane forge?

Thanks for help.

Probably not - most forge liners need to be rated 2600 F or better. Try a ceramics or pottery house; they have similar material rated to higher temps.

Will it work, maybe. Will it work well, not likely. Besides if you want to go that route you can probably find the same in a store that sells wood burning stoves without the shipping costs (and maybe cheaper), I've lined a stove with similar for less from just such a place.

But as HWooldridge says there is better material out there.

I found those at a big box store up here. These are the half thick ones. I use it as a base for my coal forge table.

I use those for the consumable floor of my forge. My burner slowly makes a crater and eventually burns through the brick. Flux makes this worse. They also provide little insulation. The entire brick glows after a few hours for me. I bought them locally at a big box in the fall.

I would say yes, but it is marginal.

In general you want insulative firebrick for a propane forge save for the floor as mentioned.

You can use the hard stuff but you will use a LOT more propane to get and keep your forge at temp; more of the "I want to save $20 so I can spend $200 extra on fuel" sort of thing.

Check for a local pottery supply and see what they have for kilns.
