AI Thread Summary
Retrieving a painted image from a rusted galvanized sign is challenging, especially if the original logo has significantly deteriorated. The discussion suggests exploring chemical processes, with one user humorously recommending aqua regia, a potent mixture of hydrochloric and nitric acids known for dissolving metals. However, caution is advised, as such strong chemicals can damage the underlying metal and may not effectively reveal the faded image. Alternative methods, such as careful cleaning or using less aggressive chemical solutions, could be considered to preserve the integrity of the sign while attempting to recover the image.

hello.
I am wondering if there is anyway to retrieve a painted image from a galvanized sign that has rusted over.
The original logo/name was likely painted in black stencil over galvanized sheet metal. I have not seen it in person yet, but from pictures it looks like image is gone and whole sheet is rusted.
Is there any chemical process to retrieve the outline of the image?
Thanks!

maybe toss it in a bath of aqua regia and see what develops:biggrin:
 

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
