gold decorations on glassware and porcelain

[macfixer01]

Does anyone know from experience if the textured 22k gold ceramic pieces (such as the type of surface that looks like drips) have more gold than those with a smooth surface? It would seem logical since the ceramic surface underneath is smooth, but the glaze is much thicker where the drips are.

Are you certain these aren't double glazed?

Once to produce the surface and then again to apply the color.

The pottery you are refering to is called weeping gold.

Qst42know,
Hmmm I hadn't considered that, but it seems likely though now that you mention it. I guess I need to locate the box where I stuck those pieces until I got to them, and try some scraping.

Thanks,

0 degrees C is warm enough for me to get out there and try some of the things I have only read about here during the cold winter nights.
I have been collecting mostly 22k and 24k ceramic, glassware and anniversary plates from the thrifts stores this winter and I am now running it through mauriatic + Bleach. Here is a sample picture.

Well after 4 24k gold rimmed plates, various shelf nic nacs, and some small gold serving ware, I ended up with .25g of black powder. I knew it would not be much when as soon as I put the ceramic in the mauriatic + Bleach the gold instantly dissapeared. I cost me more to try this experiment than the gold recoved. Oh well. Live, learn, and have fun.

hello...i liked your post...seemed very simple, but as i am new i need a little help...i will try for the first time...i have 45 piece gold plated rims porcelain set waiting to be recycle...can you tell me how to make the solution and after the gold is dissolved how do i get the gold out of it?...i dont have much knowledge about it but i learn fast...i just need a "teacher"...

I did a batch of some gold plated "Halls" porcelain pieces, some gold rimmed plates & some rimmed glasses. Even with four good sized mugs that were completely gold covered, the yield was quite a bit lower than I was expecting. I ended up with .5g from the whole batch. I have several more pieces to do but was anxious to do a sample batch to see what to expect. These are worth doing, in my opinion, but not if you have to buy the dishes.

would you teach me how did you get the gold out of that?...i am new and i have 45 piece porcelain with gold plated edges...i am crazy to try it...thank you...

Gold plated glassware is a great place to start learning the refining process. You don't have all the base metals to deal with, but my advice to you is learn about the chemicals used in refining before attempting to use them. Hydrochloric acid (HCL) is one of the more commonly used chemicals. It would be a good one to start with. The MSDS is available here: http://www.sciencelab.com/msds.php?msdsId=9924285
You don't have to touch a chemical for it to cause severe damage to you or others nearby. Many have harmful vapors that can be deadly. Learn how to safely handle chemicals before you use them (sometimes after is too late). Get some chemical resistant gloves, goggles, and an apron. Everything you need to know about how to get the gold from glassware is already posted here on the forum. Do a search and I'm sure you will find it. When you do, remember, safety first, no amount of gold is worth your eyes, hands, or your health.

Hi daiene1979!

You'll need HCl & Clorox (bleach). You then dip the items until the gold dissolves from the ceramic. If it starts to take to long for the gold to dissolve, add a bit more bleach. After all the gold has been dissolved, heat the solution for a while, but DON'T BOIL! The heat will get rid of the bleach.
Then you will need SMB, (sodium metabisulFITE, NOT sodium meta BISUFATE).
Allow solution to cool, then add slowly the SMB & the gold will start to precipitate.
Then you will have to rinse the precipitated gold.
You have to do a search & you need to read.

WARNING:
When you mix these 2 chemicals you produce chlorine gas, ITS DEADLY! :evil:
I echo what Claude recommended, "READ, READ, READ". Get the protective gear. Don't do this until you do the research; you'll live longer!

Take care!

Phil

That was 100% clear!...i already have protective gear...i will by the chemicals and read until i feel confident...i will post pic. and details later...thank you for your time...it helped a lot!!!! 8)

A quick note about the Clorox Bleach. Don't get the anti-splash or the scented kind, just get plain Clorox. :|
