Bronze Cold Casting

    Can anyone please briefly tell me the main differences and techniques between bronze cold casting and normal resin casting? I am familiar with resin casting but would like to have a go at cold casting. What additional kit would I need?

    Hi Dan,

    The process is pretty much the same, only difference is you are adding Bronze powder to the mix, there are two ways to do this, one is you add heaps of the powder to the actual resin which will will give the finished cast a bronze effect and a hefty weight to it. The other way is that you brush the inside of the mold with bronze powder before pouring the resin, the end casting will be bronze but only on the outer surface, this is a far cheaper option as bronze powder is not cheap.
    I have tried both options and I liked the first one due to the piece felt heavy and more like a real bronze casting. One thing I did do was colour my resin deep brown which gives a better result with the bronze powder.

    If you look on youtube there are plenty of videos showing what to do.

    All the best

    I agree with Steve on adding bronze powder to resin. There are some issues casting as the resin can be very thick and hard to pour and fill all voids. One way to counter this is to paint a layer of resin with bronze powder on each side of your mold. This helps to eliminate surface bubbles. You have to work fast. One other way, cast in normal resin and then use a bronze paint mixture that contains powdered bronze and comes with chemical agent to age bronze. Same aging you would see on bronze that is out in the weather. You can also highlight the bronze paint with light sanding of very very fine steel wool. Good luck, hope to see some finished product.

    Once cured, I give my bronze castings a brush with a soft brass suede brush to emphasise the patina - it just puts a metallic sheen on the highlights.

    And if you like Bronze
    I have seen in an exposition in Chateau Pommard a "Montre Molle" bronze, 2,50m high, 10 exemplars existing for a mere 1.000.000€ :)
