I have some 100% acetone that came in its own plastic container. Question: any suggestions on what container I can buy that can be air-tight sealed while soaking a coin in acetone? I know that glass is fine, but besides placing a flat glass on top of the glass jar, any other way to seal it? Any other material that is safe for coins and does not react with acetone?
Thank you. Edited by NJcoppers

For cents and nickles I just use a shot glass then cover it with a bit bigger drinking glass. The shot glass holds the coins about in the middle of it so both sides get an equal soak - no need to flip it as if were laying flat in the bottom of a container,

I have a few small glass jars (available at Amazon) and soak with the jar sideways so the coin only touches the jar at a couple of points and the acetone can hit both sides of the coin at the same time. Like this (but this one is soaking in olive oil):  Incidentally, acetone usually eats through plastic so I'm questioning the container you mentioned. Glass is definitely preferable. |

Look for a glass baby food jar or a glass pickle jar.

Neither of these is transparent, so glass has that as an advantage. Clear plastics like acrylic, polycarbonate or vinyl are not good choices for acetone. Edited by tdziemia

Of course I had to try to find out what the original jar contents tasted like when I emptied the jar - no wonder kids don't like it.

Acetone is highly volatile so if you're not in a well ventilated area, the fumes could get to you. I do all of my acetone work outside, bringing the jars inside for soak time. |

Thank you all for the excellent tips! I like both the baby-jar and the shot glass ideas. Only one concern about the glass jar: Doesn't the jar lid have some sort of rubber or soft plastic seal? Wouldn't the acetone vapor eventually attack that?

The lids on mine are described as "smooth black foam lined lid for an airtight seal". They've held up pretty well for me so far. The product page is here. |

Wouldn't the acetone vapor eventually attack that? Yes, depending on on the material used for it. (I wasn't gonna go there, but since you brought it up ...) But you care about the coin. So check occasionally whether anything looks off. If you don't want to be bothered with checking it, then your options are: glass, ceramic, metal, PP, HDPE. |

You could try a science catalog for all glass instruments. Can't remember the name right now but I think one was called science surplus or something like that. Those places have many all glass item and some are Pyrex. Try https://www.sciplus.com/Edited by just carl
