Awesome thanks for that. So next Q will be what is an AGR brace... off to Google

29g of water so 29ml

So didn't believe earlier result so made something to measure better. This brings me to 29g and a density of 7.4g/cm^3. That I believe is around the stainless steel mark. Few pics for entertainment value😃

Tried that with a saucepan and tray as only things it would fit into. On our scales that came up with a weight change if 19 to 20g so 19 to 20ml. That leaves us with a density of 10.8 to 11.3g/cm^3. Kind of rules out zirconium. Good thing is all the old coffee has now washed off it looks...

That's creating lot of fun and mess in our kitchen. It weighs 216grams. Trying to work out volume using std kitchen equipment is proving a lot harder. Water everywhere 🤣

I also have no idea how to tell if it is zirconium 🤯

Hi I would fully expect it to be a research / prototype piece as that was his side of things rather than being involved in running a reactor. Have taken pic with ruler to show dimensions. It's approx 13cm round. Seems to be 12mm ish for hole. Where I put the drill bit.

This one shows what I mean about the support faces. The curved face of each of those raised sections makes a perfect circle. Exactly the same size on every hole.

Pic showing raised and filed edges

I think it maybe stainless but not 100% on that. Some edges are filled down will attach pic to show. It's very impressive engineering considering it was made in the 1970s best guess. I was told what it was when I was very young and have a vague memory of it being something to do with a cooling...

No I don't believe it was ever used.

Does anyone know what this is. It became my dad's coffee mug mat for as long as I can remember and it is something I have of his now he has gone. Its was a part of something from his work at a nuclear research establishment. Any help would be appreciated.
