anybody know if all white bricks ( sort of slightly chalky/crumbly)

are fire bricks?

I want to do a spot of brazing and know that if I surrounded the work with the correct bricks, I'd use less gas/get more heat.

A mate has some in the back of his garage that I can have - but we don't know where they came from.

I thought proper firebricks were beige . . ish.
I would think any brick that's been fired would help in the heat containment though.

Do not follow, I may not lead. Do not lead . . . I may not follow.

Sounds like the sort of stuff they use for lining pottery kilns, exactly what you need.
But that's a guess ;)

Sugar loaf must be an exception;) .. though I guess that will burn.

I have some firelighters here, been at back of utility room cupboard for 20+ years.
Has slight odour of shoe polish..but that's kept in same cupboard.
Profile is more like nougat than chalk and has little weight.

I bet you're trying to make Home made diamonds:

My limited knowledge of fire bricks is that they often weigh more standard bricks.

Your description sounds more like a breeze block - albeit coloured. I wouldn't expect any thermal block to be chalky in texture.

They could well be Midhurst Whites, if they are standard brick size and a white colour.

These, as the name suggests, were made in the Midhurst area of Sussex and are not firebicks, but ordinary facing bricks.
