What material in the cannons?

I am a bit confused.
Were the cannon mades from 100% copper or was it bronze, i.e. copper with 10-20% tin.
And what was the colour of these cannons after 300 years in water containing 0.5 % salt?
I saw that the gun carriages were painted black, but that looks a bit boring on my new deAgostini model I have started. So I will use teak-stain which gives an aged oak-look.
And what about the red colour which much of Vasa was painted with? Was it "good-old" Falu Rödfärg?

  • Hi Tommy!

    The alloy in the guns varies quite a bit, from 90% copper to over 98% copper. The average is about 94% copper, 5% tin, and 1% impurities (mostly lead and zinc). They are a violet brown color now. The new cannon we cast in 2014 was very coppery in color at first, and has since dulled to a reddish brown.

    The red is brighter than the typical Faluröd one sees today, which tends to be more of a crimson or even maroon.



    This is how we painted our 1:10 model. The red is more of a scarlet, with a strong orange rather than purple hue.

  • Hmm, I tried to paste a picture of our model into the last message, but it did not seem to work.
