Spa Plating’s Silver Electroforming Solution plates a ductile matte-satin layer of silver that can plate to a thickness in excess of 1,000 microns. It can be easily burnished or polished.
Our Silver Electroforming Calculator will help you silver electroform to your desired thicknesses and also guide you in maintaining your solution in good working order with the correct additions.
We have been able to keep the cyanide content of this solution to a minimum and it is rated as a category III toxic substance which is at the lower end of the toxic spectrum.
We can only sell this product to business that are VAT registered.

- Three different speeds are available; low, medium and high. Greater
levelling is obtained at a
lower plating speed, whereas brighter but less levelled deposits are obtained
at a higher plating speed.
- Anodes should be bagged to avoid particulate matter entering the
solution and causing roughness.
- This is a low-cyanide type silver plating solution. When not in use the
plating solution should be
hermetically sealed to minimise ingress of oxygen that can rapidly deplete
it. If using a plating beaker,
sealing can be achieved by covering with PVC cling film and securing with an
- Maximum levelling (smoothness) is achieved at lower cyanide levels and
low plating speed (at or below 0.005 A/cm2).
- Free cyanide (as KCN) depletes when kept in an open container at
approximately 10g/l per month and in a hermetically sealed container at
approximately 2g/l per month.
- If you wish to use this solution outside its shelf life, you will need
to add potassium cyanide in order
to raise the free cyanide level. There are a number of sources that sell
this compound throughout
- We have succeeded in keeping the cyanide content of this solution to a
minimum and as such is rated
as a category III toxic substance, which is on at the lower end of the toxic

- The silver coating is easily burnished (either in a barrel polisher or by hand) to
a mirror-bright finish.
