some pyrites are stable, some aren't. The ones that are stable don't rust. The others do. You will have to wait and see?

Hi,
There are Spanish slates and there are Spanish slates, The Cupa R12 excellence, is, in my opinion one of the best ( from Spain ) I have been selling it for over 15 years without any problems at all ( In the region of 4m slates )
I very rarely see pyrites in them, but occasionally, when cut with a disc cutter, they can be seen.
Spanish slates will never be as good as Welsh, but the R12 is one of the best available !

If only it were 'real' gold! Okay. So have I purchased junk? 1200 of these Cupa R12 slates are currently stacked on my scaffolding awaiting installation. I'm caught between a rock and a hard place. If these pyrites are deemed to be the 'stable'kind would the slates be fit for purpose in the UK? I have no experience in this area. Is this level of inclusion deemed to be completely unacceptable? I spoke to the Cupa agent for my region and he said that all slates contain pyrites and if I spoke to my building merchant they would arrange to send the barcodes from my pallets to Cupa who would provide me with a guarantee.

If it is "real" gold, you just made a fortune. If it is "fools" gold, you may have a problem. Spanish slates are great in Spain, but most of the time, they sell the good stuff over there and send the junk over seas. That includes "Here"

Hello all. Advice gratefully recieved. I've recently purchased 1200 'Cupa R12' spanish slates to replace the roof of my small cottage. As I finished stacking out the scaffolding prior to installation I noticed sparkly gold inclusions. I closely examined the rest and found that 30% of them contain streaks of gold that are visible on the face. Around a dozen slates had the corners trimmed off and the cut edge was full of gold inclusion. Should I be worried? Attached is a picture of the cut edge
