Q. Hi all,
This is Rajesh from India. I am Hobbyist of wax art. Recently I read some article on hollow article prepared by using electroforming.
My idea is to create a wax art, paint it with electro-conductive material & electroform it using silver. I have searched a lot for electro-conductive paint for wax, but unable to locate any.
Please suggest me with the best option to do this (cheaper is preferred).
Thanks in advance.

Try graphite powder
⇦this on
eBay
or
Amazon [affil links] or bronze powder
⇦this on
Amazon [affil links] . You may prepare your own conductive paint -- simply mix bronze powder with very diluted nitro lacquer
⇦this on
eBay
or
Amazon [affil links] .
There are some very good infos on D-I-Y electroforming, some good and download free books on electroforming can be downloaded from internet archive website (even booklet by M.H.Jacoby -inventor of process/in german -- but try google translator, it is free. Hope it helps and good luck!

A. Hi Rajesh,
A lot of people are doing electroforming on wax. Silver conductive ink
⇦this on
eBay
or
Amazon [affil links] is the best option and is available. Try looking for it.

A. Silver Electroforming can be done on wax in a Silver Potassium Cyanide Electroplating bath with higher metal concentration.
If the wax piece is finished properly than the result will be good ... Use a fine copper powder
⇦this on
eBay
or
Amazon [affil links] mixed with NC thinner
⇦this on
eBay
or
Amazon [affil links] and NC lacquer
⇦this on
eBay
or
Amazon [affil links] and spray it on the wax, this will make the wax conductive ... rest of the electroplating process. If you want to make it hollow than you will have to deposit higher thickness, drain out the wax, and after that do the surface finishing. We are doing silver electroforming very effectively using the above process ....

A. Brass powder or gold powder or graphite powder; 3 powder : 2 lacquer : 16 thiner
Silver electroforming: 1-silver p cyanide, 2-potassium cyanide, 3-potassium carbonate, 4-potassium hydroxide, 5-antimony potassium tartrate, 6-selenious acid.
Good luck.

Is it necessary to remove wax from hollow electroformed jewelry?
Q. Please tell me if I have to empty my electroformed gold pendant of wax for sale and how can I do it?
Best regards,

A. It is not necessary to remove the wax, but doing so will make the electroformed product much lighter! You will, of course, use a low melting point wax and have designed the electroform to have an escape hole for it, so all you do is carefully heat the electroform to a suitable temperature and the wax will flow out. Alternatively, you can use a suitable solvent, but that will depend on the type of wax used.
