Electroplating copper articles with either gold or silver

I want to have my some copper articles at my prayer room and some articles to adore the deity's idol. I have seen that many artisans with a small setup they do electroplating (Silver plating and Gold platings) with mere 12V DC. I want to try that at home at home. I want to know (i)what chemicals are used as electrolyte what should be its concentration? (ii) If I want to electroplate copper bengals with gold, how long I should run the process? This for hobby.

Thnk you so much.

Ferrocyanide silver plating bath(nontoxic but never mix acids and solution):

10 gm silver chloride
20 gm potassium ferrocyanide [affil links]
20 gm potassium carbonate
40 gm sodium sulphite
1 lit water,SS anodes,2-6 V,o,5 A/dm2

gold bath:

2,5 gm gold chloride
15 gm potassium ferrocyanide [affil links]
15 gm sodium carbonate / washing soda [affil links]
1 lit water, SS anodes

Dissolve ferrocyanide in boiling water, then after it dissolves, add carbonate, add sulphite (for silver bath),add silver,boil min. 30 minutes, add gold, must be filtered (cold), distance cathode-anode minimum 15 cm!
