With our coloured gold mixing kit you’ll have everything need to get started on creating your own bespoke shades of coloured golds.

The syringes and beakers included in the kit will allow you to accurately measure out small, economical quantities of our K-Gold Brush Plating Solution. You’ll then be able to measure out the precise amounts of our rose and green gold mixers to create the alloys and shades of gold commonly used in jewellery making and other crafts. These could range from 9kt Whitish gold to 23kt Yellow Gold.

Our K-Gold Brush Plating Solution and our rose and green gold mixers can be used with our pen and brush plating equipment. We strongly recommend using carbon electrodes for both pen and brush plating when plating your mixed shade of gold. Links to these can be found in the ‘Related Products’ section below.

We have included one of our Storage Syringes in the kit so that you can safely store your K-Gold Brush Plating Solution to prevent degeneration of the solution over time.

Please click on the blue tabs above to see pictures of the alloy samples, a video of how to measure out and mix these solutions and a plating calculator that tells you the amounts of solutions needed to create your desired gold alloy/shade. The ‘Process Sequences’ tab goes into detail about the ratios of K-Gold and mixers and includes more practical information about finishing, voltages and plating rates.

This photograph shows the range of commonly used alloys and shades of gold that are used in the jewellery trade and that can be created with our Coloured Gold Mixing Kit. Please refer to our Coloured Gold Mixing Calculator to find the ratios of K-Gold and mixing solutions that will create your preferred shade/alloy of gold.


There are two ways of mixing our coloured metal mixers – either by weight or by volume. If you want to use the former method, you’ll need to use a set of scales, whereas with the volume method you can measure out using our syringes.

How to fill your storage syringe with plating solution

Storing your rose gold brush/pen plating solution and k-gold plating solution in a syringe will ensure you minimise any deterioration of the solution due to exposure to air.

1. Fitting the needle

Screw the needle into the syringe.

2. Filling the syringe

Draw the plating solution up into the syringe.

3. Clearing the needle

Pull any solution that is still in the needle back into the body of the syringe.

4. Clearing the air from the syringe

Squeeze the plunger of the syringe until a little plating solution comes out of the needle. This will clear the syringe of any last remaining air pockets.

5. Capping needle

Fit the red cap to the end of the needle.

6. Filled syringe

The filled syringe will now keep your plating solution ready for use. Please see the relevant plating solution product page the under ‘Tech Specs’ section for storage guidance.

Please refer How To Use This Calculator below

How to use this calculator :

1. In the first box, enter the shade and karat value of gold that you wish to mix.

2. In the second box, choose whether you wish to measure the components of the mixture by volume(V) or by weight (W).

3. In the third box, enter the volume or weight of K-Gold that you wish to mix.

4. Press the ‘Calculate’ button.

5. Read off the amount of mixers to add to your chosen amount of K-Gold.

Notes :

For the Short Swab on a Carbon Electrode, set rectifier to 2.5 volts.

For the Extra Fluffy Swab on a Carbon Electrode, set the rectifier to 3.0 volts.

For the Pointed Nib attached to the Carbon Pen Electrode, set rectifier to 2.7 volts.

Always use a new or nearly new swab for this process.

Use the plating solution within 1 hour of mixing.

When plating on to stainless steel, nickel and its alloys, plate a gold flash layer first.

Shades of commonly used karats of gold created with our Coloured Metal Mixers

and K-Gold system.

Here’s a photo showing the shades of gold achievable using our coloured metal mixer system. Each swatch is numbered and corresponds to the swatch listed in the table following, which details the various quantities of mixer you need to create your desired shade and karatage of gold.

You can use these mixtures as guides or you can create your own unique shades.

Use our Coloured Gold Mixing Calculator to select the correct mixture of K-Gold, Rose Gold Mixer and Green Gold Mixer.

To achieve these shades you will need to use either a Carbon Electrode or Carbon Pen

  1. Gold flash or gold strike required if plating any of the above coatings on stainless steel.
  2. We recommend that dull coatings are polished with the Silver and Gold Cloth or for
    coatings in excess of 3 microns, with Autosol followed by Silver and Gold Cloth.
  3. If plating on nickel, a gold flash is recommended.
  4. Gold content (karat value) of the plate increases with increasing voltage.
  5. In mixes that contain both Rose and Green Gold Mixer, the red hue increases with increasing
    voltage. The green hue increases with decreasing voltage.
  6. Ensure the swab is fully saturated with some excess remaining in the beaker prior to commencing plating.
  7. As an example of how quickly gold alloys plate with our K-Gold system, a sterling silver wedding band
    can be plated to 3.3 microns (Vermeil for 18 karat gold) in approximately 12 minutes with 18 karat rose gold.
