Notes:
- Recommended plating factor range is between 0.008 and 0.012 A/cm2
- The plating rate varies considerably with temperature and agitation at any
fixed plating factor. - The only gold that should be replenished is via Gold Tank Replenisher; the amount to add should be calculated using our online calculator.
- Evaporation losses are made up usually at the end of the day by topping back up to the original level with deionised water.
- Rinse articles above the solution when you remove them from the tank so all the gold solution left over on the work goes back into the tank and is not wasted. If not, the gold will be dragged out and wasted.
- One litre of gold solution should last between 5 and 6 turnovers. That means that a gold solution which has 4 grams per litre of gold in it as supplied should plate out at least 5 x 4 = 20 grams of gold before it becomes overloaded with potassium and starts to crystallise out as potassium salts.
