I use a base bath frequently for glassware, it does not hurt it or bother the joints. The amount of glass removed is atoms thick, not measurable.
Only a very long time (days to months) there will ever remove enough glass to matter. HF on the other hand will etch glass in a few hours, and it
does not ever look the same again. I have a few flasks that HF was a byproduct in, and they all look bad when wet, and worse when dry. They look
sand blasted or such.
Scotch bright pads are good for cleaning the joints if they get dirty. The rubber septa will sometimes leave a film of goo on them, especially after
exposure to acid.

How can the Alpha and the Beta CaSO4:0.5H20 have different solubilities (in the long term)?
Perhaps the study did not wait for days/weeks for all to dissolve, ie. the Beta is slower???

Sulfur Chlorides Using HCl instead of Chlorine
I know this might be a dumb question, but I was wondering if HCl gas (which is easier and cheaper to prepare than chlorine) could be used instead of
chlorine in the synthesis of sulfur chlorides? Thanks.
