"glue" for insulated fire bricks?

Yes Alvin, you can use fire place cement, or a commercial castable refractory.

I've never seen it - but if you want to try - and live with the smell or the one time burn out - There is very high temp 'glue' that is used in wood stoves to glue on the fiberglass rope to seal the door.

I found it in a hardware store - it was a red thick stuff - like RTV.

What this is is like an investment - a white glaze. Often the blocks are edge or corner coated for strength.

The fire place cement is a high temperature mortar the brand is Fullers.

The castable refractory is Pyrocrete 165 arc from Foseco, which is a monolithic refractory, which means you can build load bearing structures out of it. Pour it today and use it tomorrow... heat shock resistant, meaning the home user has no chance at cracking it.

Thanks for the effort Martin but C.A in Oz posted what I wanted to hear. I know "glue" wasn't the best word BTW. ;)

I see you already have your answer, but waterglass (sodium silicate, I think) is often used to cement insulating seals to doors of wood fired stoves. I'm not sure that the castable refractory is a good "glue". Often holes are drilled in firebricks and stainless steel rods are poked through to hold non-gravity supported shapes.

It can be depending on how you do it ;-)

I was thinking that you'd stack your bricks and trowel on the pyrocrete. It's a good product, if it's good enough to be considered for a weigh bridge, then it's a pretty safe bet that it has a lot of structural integrity as well as the high heat properties.

It could be used as a mortar, but I think the benefit of having a durable hot face material would be lost.
