Keycap Kevin: stars for my 'Star Wars' style keyboard

I want to install Boba-Fett keycaps on one of my keyboards. To create an authentic 'Star Wars' look, I patinated the weight on the brass underside with patterns.

I have already tried two methods of patinating - i.e. artificially ageing - the knob surface of one of my keyboards: using heat and egg. Both of these methods are out of the question for my current project: I want to create patterns through patina. To do this, I need to avoid oxidation of certain parts of the brass weight. That is why I am using vinegar and salt this time.

The piano

For my latest keyboard, the Neo65, I bought keycaps with a Boba Fett look. What I particularly like about 'Star Wars' is the 'used future' concept. In other words, not everything is mirror polished, but the world is also dirty. Old technologies meet new ones.

I want to reproduce this style on my keyboard not only with the keycaps, but also with the brass weight on the underside. I choose stars as my motif.

To create the star motifs I use stickers.

The weight of the Neo65 is not painted. The brass would oxidise over time anyway. It is not necessary to sandblast first to remove the protective layer. I buy the star-shaped stickers so that I can create the motifs. The shape is not particularly complex, so I assume it will be easily visible. I attach six pieces to the weight.

Aceto and salt

I apply a thick layer of vinegar and salt paste.

This time I use white wine vinegar and salt for patination. Both agents accelerate the natural oxidation of brass. I therefore mix a decilitre of both to create a paste. I then paint the visible side of the weight with a brush. I leave the paste to set for half an hour. Then I turn up the heat: I put the piece of brass with the vinegar and salt gasket in the oven at 230 degrees for ten minutes. This way the brass oxidises even more quickly.

After firing, I let the weight cool and then rinse the dried paste. The brass has turned brown. For me, it is not oxidised enough. I fear that the stars are not clearly visible. So I re-coat the brass with the paste and leave it overnight.

The discolouration is already clearly visible, but still too little.

The result is impressive

The next day, I remove the paste and stickers. Underneath, the stars glow a golden brass colour. I like it. Now I could paint the weight, so that the star patterns do not oxidise. But I decide not to. I want the appearance of the weight to change over time. The stars will probably always be visible in some way. Just not as shiny, but in a perfect 'used future' style.
