Re: cleaning glass? ()

It is a powerful oxidizing agent. Dissolved in concentrated sulfuric acid it is even more so. So if one, in the day, wanted clean glass a quick swim in a vat of chromate in sulfuric acid did the trick. But this was a piddly market.

It is an exceptional passifier for corrosion mitigation on steel. It was added to brine systems by the ton and formulated in steel primers. And it was used in tanning leather.

While it is feared that walking by it may cause harm, inhaling it is the hazard that is well documented. I have shown that it persists on wood after application. I actually thought the lignin would destroy it but it didn't. Next step is sanding and you see where this is going............
