    Hi, there are a lot of smart people who contribute to this forum; I was thinking of using these (I have 2 of them) Plastic containers for Electroplating Cases and small Watch Parts. What were they used for originally? Regards Ray View attachment 346954 View attachment 346955 .

    Possibly for producing or
    demonstrating an electric arc?

    The top device would allow
    precise adjustment of the
    distance between the spherical
    ends.

    Another (possibly better?) guess:
    an apparatus for measuring high-
    voltage DC, by the length of the
    spark produced.

    Hi LloydB, it is a water tight container when upright; I wonder what sort of liquid was in it? Regards Ray

    Maybe measuring the breakdown voltage of an inert gas. Would not want to put methane in it, but it might be OK if you knew there was no oxygen mixed in. :devil:

    Thanks LloydB, I don't think I will be using it for the intended purpose; it sounds pretty lethal. Maybe not depends on the Amps. Regards Ray

    If the containers are liquid proof my guess is they are used to test the dielectric strength of transformer oils.

    I've used a similar bit of kit to measure the voltage from a Van de Graaf generator but that was airgap, no tank involved. I think in this case the voltage is known but they are testing the dielectric strength.

    Assuming that the tanks are plastic, originally clear, their brownish color sure looks like they've seen transformer oil. High voltage engineering uses lots of spark gaps for one thing or another. They're notoriously inaccurate as measuring devices and untrustworthy as safety devices (that is, to allow currents to bypass vulnerable equipment), but in many cases they're the best alternative we've got.

    It's not clear how these would be of use in electroplating.

    Hi M Kinsler, I was just going to use the container. I have a variable Voltage Power Supply. I just was curious what they were used for originally. Regards Ray
