AI Thread Summary
The discussion centers on the restoration of a painting affected by a chemical reaction between the paint and varnish, potentially due to aging. Participants explore the possibility of restoring the artwork through varnish replacement but express concerns about whether the reacted paint will remain discolored after varnish removal. The difficulty of selectively removing lead from the pigment is noted, emphasizing that the restoration process could be complex and time-consuming, potentially requiring meticulous work over months or years. This contrasts with Vincent van Gogh's prolific output, where he created numerous paintings in a short time frame, highlighting the challenges faced in modern restoration efforts.

from old age, maybe but also due to a chemical reaction between the paint and the varnish

They already suggested varnish replacement, didn't they?

sure, but will the reacted paint also disappear with removing the varnish?
 
No idea. If the pigment is not removed, its discoloration should not change. Selectively removing lead from the pigment can be difficult (although it doesn't have to be impossible, a lot depends on the exact composition of all substances involved).
 
Right, maybe it has to be restored with square mm's at the time, which may take months if not years. A bit weird considering that Vincent van Gogh painted oh several dozens paintings a month with a peak of 80, the month before his death
 

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...
