Notes:

 

  • 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.
  • Please note: It is possible to use our Copper Electroforming Brightener with home-made
    sulphuric acid base copper electroforming and copper plating solutions provided
    that the solution has not had any brighteners added previously.
    For home-made solutions add 25ml of Copper Electroforming Brightener
    for every litre of home-made solution.
