Mood: No Mood

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.

Can anyone with some geology experience verify if this is actually cinnabar?
