This will produce minute amounts of chlorine gas due to the salt, so I wouldn't recommend doing it indoors.

@masyn92 i know that now, this video was just posted a long time ago. I'll put an annotation up somewhere on the video :P

I worked in Electroplating for 5 years, a touch of potassium cyanide will help the zinc transfer across. just don't lick your fingers...

[coolsciencetech]

What did you do while you worked in electroplating? And yea i definitely wont lick my fingers

I tried this procedure and it worked, but my plated metal objects are covered with black sticky substance which is pain to remove.

I found that using NaOH (caustic soda) 30% solution as electrolyte gives much cleaner result.

I also tried HCl and it didn't work.

That black stuff seems similar to what i got when my solution was too cunductive but mine didn't plate when i did that... i'll have to try that 30% NaOH trick... I have never tried HCL what was the concentration?

@masyn92 One could use Espom Salt instead, it doesn't produce chlorine gas

[masyn92]

You can use sodium bicarbonate (Baking soda) instead of salt, for anyone without a fume hood or just doesn't want to be around chlorine gas.

panu daw?? pde pong pkitagalog ksi proj po nmin.. hahaha... mraming salamat...

i use an old electric train reostat, which is great cause i can easily reverse polarity

Que merda !!!

Wow how long ago did you do that they dont even use that stuff anymore. Ive been doing it for 6 years and we have acid chloride baths and alkali baths and potash and ammonium chloride are used instead of cyanide

right now im doing it with 30 volts its fun to watch but lets see how it comes out, its definatly gona be uneven :P

Worked for a small company in the UK, Barrel plating line, long time ago now... You can also try a little zinc oxide in the solution but this also raises the sodium hydroxide levels.
