How to test gold at home with bleach

How to test gold at home with bleach. Gold is by far the most malleable of all metals, despite its strength. Because pure gold is too soft to endure the strains of everyday use, it is mixed with various alloys to increase its strength and longevity.

To check for genuine gold, use bleach. It is unlikely to destroy authentic gold jewelry, but it is likely to ruin fake gold jewelry.

Although bleach is quite similar to nitric acid, that’s not as reliable as a test. It can verify the authenticity of your gold, but it doesn’t determine how pure it is.

Real gold is exceptionally inert, while imitation gold can cause color loss. Using standard household bleach as a simple home test for actual gold is a good idea.

Bleach testing isn’t a foolproof method of determining whether something is gold.


With the use of common household materials, you can authenticate your gold at home. Use just ordinary chlorine bleach to perform the bleach test.

It would be best if you did not use colorfast or perfumed bleach. You may include other substances in these bleaches, which might cause adverse reactions.

Follow us as we look at how to test the gold with bleach, which is readily accessible.

  • In a glass dish or cup, pour just about enough bleach to saturate the piece you wish to test.
  • You don’t require much.
  • Make a scrape on the probable gold covering in an out-of-the-way location. Any gold plating must be scratched deeply enough to be penetrated.
  • You must keep a close eye on everything. The reaction may be subtle. On the thing you’re testing, keep an eye out for color changes.
  • There may be telltale bubbles or a color shift in the bleach. If any of these conditions are present, the object is either gold-plated or not genuine gold.
  • Remove the jewelry from the bleach as soon as possible. Clean the material you tested entirely under cold running water right away.
  • To avoid additional harm, you should eliminate any residues of bleach. Dry the object entirely before discarding the bleach.

There are a variety of less harmful methods for determining the gold content of a piece of jewelry. The majority of them do not necessitate any item damage.

In some circumstances, other tests and signs may provide you with even more information than a home bleach test.

The bleach test may not be the ideal solution if the item of jewelry you wish to examine is a family treasure. Many old items of jewelry were gold plated or comprised of an alloy of base metals.

A bleach test may destroy jewelry that is plated or made of gold alloy.

If you attempt to ascertain if something is gold by destroying it, you risk losing a lot of money.

Sometimes, a modest quantity of gold is worth significantly less than the piece’s inherent value.

Rub the stone against a clean cloth. Rubbing it against a cloth will cause a ring to form, which rubs away with a few more rubs.

If the ring either doesn’t rub off or rubs off too easily, your stone will have to be washed and rechecked because you originally had a higher karat gold.

Wash the stone in a baking soda/water mixture, then rinse it in water and pat it dry with a paper towel before trying again.

If you want to test the purity of gold, you can go about doing so simply. The first thing you need to do is take some liquid foundations and pour them into your hand.

By using a makeup sponge and spreading it around, blend in your foundation with your skin. Once the foundation has dried for a little, apply gold onto that area with a damp cloth or something that is made of gold.

If the area turns black, then the purer the gold is, but if keeping its color means it contains impurities, then its lack of blackening indicates that these other metals are mixed in with the gold.

A gold bleach test is far from conclusive. Some natural stones may be damaged beyond repair if they are exposed to bleach. In the bleach, specific old manufactured rocks and decorations may entirely melt.
