Beaker ring for holding the electrodes for our tank plating process. It comes in four sizes according to the volume of your Plating Beaker; 250ml, 500ml, 1litre and 2 litre.

The Spa Plating tank plating process has been designed to provide the greatest degree of flexibity for our customers. It allows you to plate a wide range of differently sized objects with a variety finishes. Pictured is one of our 1 Litre electrode rings fitted into a 1 Litre Plating Beaker with the full quota of 6 copper electrodes for tank plating and the corresponding number of our anode bags.

Copper electroforming on stone

This project shows you how to copper electroform on stone using a slice of agate as an example. This is demonstrated using our Conductive Paint, which can be used for electroforming on a wide range of non-conductive surfaces.
Our Conductive Paint can be purchased through our Special Orders shop and can only be shipped in the UK and the EU.
The benefit of using this paint is that it is a much quicker option than using our Conductive Ink (hi-grade). This is down to two main factors;
depending on the material you’re electroforming onto, the Conductive Paint can be applied without having to first spray on a key layer of lacquer. This is great if you’re intending to selectively electroplate, as you don’t have to do any tricky masking out.
The second factor that makes it a quicker option is that it becomes touch dry in 4-6 minutes and fully cured by 1hr at 60 degrees centigrade.
This considerable advantage needs to be weighed against certain other factors. In this project we’ll be showing you how to prepare a slice of agate for electroforming. Agate is predominantly made of silica and therefore won’t be attacked by the Copper Electroforming Solution. However, if you were intending to selectively electroform a shell, you would have to cover the entire surface in lacquer before you applied the Conductive Paint. This is because shells are made of calcium carbonate which would be attacked by the Copper Electroforming Solution.
Conductive Paint can only be painted on and if you were planning on electroforming a very smooth surface, the brush marks may show up. In this case, you would need to use our Conductive Ink (hi-grade). Also, the Conductive Paint takes longer to build a shiny layer of copper.

Stage 1. Surface preparation for electroforming

a) Assembling your kit

Get together everything you need for preparing the agate slice; this will include the Conductive Paint, The tubes of Conductive Epoxy and a jump ring to hang the agate piece on the chain, once it is electroformed.

At this stage you need to work out the surface area of part of the item you’re intending to electroform. The rim of this slice of agate was 3.5 cm squared and this was noted for later use. It will also be useful to have your Conductivity Tester to hand, to check that the Conductive Paint and the Conductive Epoxy Filler you’ll be applying is, in actual fact, conductive.

Mix the Conductive Epoxy according to the instructions on the packet

b) Painting on the Conductive Paint

Carefully paint on the Conductive Paint around the rim of the agate slice, using the enclosed brush. Once this is done, either leave to dry at room temperature (25 degrees centigrade) for 24 hours or dry in a fan oven at 60 degrees centigrade for an hour.

c) Using the Conductive Epoxy

To attach the jump ring to the rim of the agate slice, mix up a small amount of our Conductive Epoxy Filler and use this to stick the ring directly onto the dried Conductive Paint. The ring now performs two functions; it allows the piece of agate to be hung from its chain and it also forms the conductive connection that the agate can be held by in the electroforming solution.

Stage 2. Electroforming the agate slice

a) Working out amp settings and electroforming time

Work out the amp setting and electroforming time by entering in the surface area into our online Electroforming Calculator. Then set up your electroforming equipment following the instructions detailed in another section of this manual called ‘Copper electroforming a plastic model soldier


b) Using the Electroforming Calculator

The surface area of the rim of this slice of agate is approximately 3.5 cm squared and the required thickness of the electroforming is 100 microns. These details are entered in to our online Electroforming Calculator and this produces an amp level of 0.175 and a plating time of 1.30 hours.

c) Finishing

The finished piece of electroformed agate was taken out at the end of the alloted time and given a rinse. It is now possible to apply other plated layers of silver or gold, for example using either tank or brush plating or a combination of both.
