    Not that it really matters, but I am not seeing a correlation between crucible sizes and copper mass in kilograms.
    Here is a Morgan Salamander Super A chart.

    Copper is slightly more dense than brass.

    For example, for a #10 crucible, the brass capacity in kg is 18, and the kg for copper would be higher.
    That is like a 2:1 difference, and so no correlation.

    Maybe I am missing something.

    I could see that.. Brass being 35% zinc... Zinc should be lighter than copper.

    One online source (not sure how accurate) gives the following:

    Brass: 0.3034692528 lb/cubic inch

    Copper: 0.32174966 lb/cubic inch

    .

    Not me.
    I hardly remember what I did yesterday.

    Edit:
    Hey, I like that signature. :)

    I don't know how they can say "X kilos of Brass", there are many compositions of brass. All them have different densities.

    Good point. But what's the most common? Yellow brass? Bronze would probably have the same issue, 31 flavors.o_O

    Brass density varies by around 2.5% with different alloys so on a 1Kg pot you could be plus or minus 12.5 grams, I can spill more than that on the way to the mould.

    Anyway, I miss-spelt my google search and typed 'bra density' so I seem to have date with 'busty of Suffolk' so I'm going to leave it there...... ;)

    Just saw the Salamander chart above. I thought my crucibles were an A10 size but according to that they are actually an A16! Pretty heavy when full, I thought I was just getting old, I feel better now.
