There are solvents and acids that will dissolve gold, but not many. And they aren't "over-the-counter" products. Aqua regia, a mixture of hydrochloric and nitric acids (3:1) will do the trick. But this is dangerous stuff! There are other solvents, including cyanide and Mercury. These substances are poisonous and toxic! Let's chat for a moment. Here's the thing. The amount of gold on the vase is almost too small to measure. The scrap value (even if you could get it off with a snap of the fingers) would only be a few bucks. The layer of the metal is only a few tens of microns thick. You'd be lucky to be able to eat a meal at your local McRestaurant for what you get for the gold. The cost to obtain the acid (even if you could get it) would exceed the scrap value of the gold. (And how are you going to get the gold out of the acid after you apply the acid to the vase to get the gold off of it?) The experts on the recovery of gold film are the electronics parts recyclers. And they won't spool up for a half dozen circuit boards. It costs too much to do small productions. They can't set up shop for such a small quantity of boards. By the way, a half dozen circuit boards will have more gold on them than a half dozen of your vases. In the first part, your question was answered. In the rest, you are asked to see the "illogic" in trying to recycle the gold on a single vase.
Most online and mail-in services pay for all shipping when you sell scrap gold to them. Some of them can email you the shipping label so that you can send your items sooner. Others may need to physically mail you a wrapper and label, and this will delay your efforts to sell scrap gold. If you need to sell scrap gold quickly, look for one that can provide you with a printable shipping label you can use on your own box.
Jewelers RARELY use old gold for casting, as it corrupts the casting process due to the nature of the metal and other impurities. Most of the time when they tell you they are using it, they are NOT. There is a product called CleanCast that helps the process, but fresh gold is ALWAYS better. If you use gold that is old, you can't be assured of the quality of the outcome. Poracity, crystallization of the metal and poor flow will make your piece look bad. A good jeweler will credit you for your scrap gold but most probably use his own refined gold to cast a piece
if you have a spatula use that and scrap that into the trash
Personally.. given the worth of a GMC, I would use a stick of dynamite to remove the dash.. or refer the vehicle to the local scrap yard.
Yes. The best vase to use for a single rose is a tall, slender, glass vase.
check inside the vase for the red ant. That is how you use it lol.
They are used everyday to move scrap iron around the scrap yard...
Yes, you can use a vase as a planter for your plants, but make sure it has proper drainage holes to prevent overwatering.
You can use polish to make that old vase shine again, but make sure it won't damage your vase first.
Steel investment foundries make use of iron scrap

In general, no. They pay only a fraction of melt value. You're better off using a pawn shop unless it's scrap gold. Google "Cash 4 Gold scam".
