Below are a list of Frequently Asked Questions. If you are unable to find an answer to your query here please contact us.

 

  • What is electroplating?

Electroplating is the process of depositing micro-thin layers of the chosen metal onto the surface of another metal (usually jewellery). This is called electrolysis and is generally done to improve the appearance of the object or to protect it from corrosion, rust or wear. Most solid white gold jewellery is also rhodium plated for whiteness. This is because white gold in its natural form is slightly yellow.

 

  • How does electroplating work?

 The item to be electroplated is connected to a negative terminal of a power supply and immersed in the bath (becoming the cathode). A copper bar is then attached to the positive terminal and also submerged in the bath (becoming the anode).

When the power is turned on an electrical current passes through the bath flowing in through the item for coating and out through the metal bar. While this is happening electrolysis of the electrolytic bath occurs. This means that the metal content of the bath is attracted to the cathode and forms a coating. When the item is removed from the bath it adheres firmly forming an alloy. The longer the power is on the thicker the layer of plating that is applied. The thickness of electroplating is usually measured in microns.

 

  • What metals can be plated?

Silver, copper and copper alloys, nickel and brass are the best metals to plate. However, for high quality results and to ensure the plating adheres well it is vital that the piece is clean and free of any grease or particles. If your item needs to be professionally cleaned prior to plating we will contact you to discuss it before proceeding.

 

  • Is it permanent?

Electroplating can thin with wear. For example areas like the inside of rings are particularly prone to wearing thin. We recommend that a minimum of a 2 micron layer is applied to most items. Ideally rings should be 5 microns thick. Those with white gold jewellery (and depending on their wear and tear) should expect to have their jewellery re-plated approximately every two years.

 

  • How much does it cost?

1. How much preparation and cleaning is.

2. The surface area of the item (how big it is)
This depends on two things.needed. The item has to be spotless and de-greased.
We have a minimum charge of £20.00.

 

  • How do I get my item to you?

 

You can post your item and we will return it fully insured, usually within 48 hours. 29 Riverwell in Ecton Brook in Northampton. NN3 5EG
We will need to see the 
item to give you a firm quotation but can give an extremely well-qualified
quote from your honest description.

 

  • How long will it last?

We recommend 2 microns for most things but for
This depends on the thickness of the plating. This is measured in microns, which means a millionth of an inch. Rings we recommend 5.
