Copper Electroforming Solution

Copper Electroforming Solution Watch Our Video

Spa Plating’s copper electroforming solution has been developed to work not only with standard copper electrodes but also with our system using rod electrodes in place of copper electrodes.
A major source of  particulate contamination, which causes both dullness and roughness, is particulate contamination from using copper electrodes.
Using Rod Electrodes and anode bags eliminates the source of particulate contamination together with the requirement for regular filtration.

Electroformed jewellery created using our Copper Electroforming Solution. Find out more in our Plating Manual. To work out how much electroforming solution you will need to electroform your item and how much it will cost please click HERE and to see a projects on electroforming please click HERE for our Electroplating Manual. Click HERE for our Copper Electroforming Calculator to help you work out how long to leave your item in the Copper Electroforming Solution to achieve your desired thickness of copper.

example usage 2

Our Copper Electroforming Solution is designed to be used with our Electroforming Kit. Please click HERE in our shopping category ‘Plating Kits’ to find out more.

example usage 3

You can keep you Copper Electroforming Solution depositing bright shiny layers for longer by adding a few drops of our Copper Brightener, our single shot brightener system. This can be found HERE in our shop under Plating Solutions: Base Metals. Our Copper Electroforming Replenisher, which can be found by clicking HERE, will also keep your electroforming bath working at its optimum level. Again, guidance on how much to use of these additives can be found in our Copper Electroforming Calculator.

Product Details

Our Copper Electroforming Solution quickly deposits a smooth shiny layer of copper on conductive and non-conductive materials and is designed to work in tandem with our Electroforming Kit.

  • Single-shot additive system.
  • Filtration not required when used with Spa Plating’s equipment.
  • Total process control using our online calculator.
  • Come premixed and ready-to-use.
  • Makes for the ideal bench-top electroforming system.
  • We strongly advise against the use of air agitation with all electroforming
    solutions due to health and safety issues associated with airborne copper mists.

  • If particulate contamination enters the solution, filter using our filter kit.
    Please note that if using copper electrodes, continuous filtration will be necessary. If using
    rod electrodes, the solution should only need occasional filtration if at all.
  • Brightener additions should be made at the start of plating if possible. Additions can
    be determined using the Copper Electroforming Calculator by clicking Here
  • Higher temperatures favour less burning on exposed areas ie: sharp edges or pointed parts.
  • Solution should only be lightly agitated with the stirring rate set to minimum. Too much
    agitation will disturb any copper residues in the anode bags causing them to enter the
    solution which will produce a rough deposit.
  • After starting from a long period of inactivity, add 5ml of Copper Brightener per litre of
    electroforming solution.
  • Build up of blue crystals is usual on the electrode ring. Remove by scraping them
    back into the solution and allow to dissolve before commencing plating.
