Part 1: Testing Gold with Toothpaste

Gather Your Materials

To test gold with toothpaste, you will need the following items:
- Gold item to be tested
- A soft toothbrush
- White toothpaste (non-gel type)
- A clean, soft cloth

Examine the Gold

Before applying the toothpaste, visually inspect the gold item. Look for any discoloration, tarnish, or unusual markings that may indicate it is not genuine gold.

Apply Toothpaste

Squeeze a small amount of white toothpaste onto the soft toothbrush.

Step 4: Brush the Gold

Gently brush the toothpaste onto a small, inconspicuous area of the gold item. Use light pressure and circular motions.

Observe the Results

After brushing, carefully inspect the area where the toothpaste was applied. If the gold is genuine, it should maintain its luster and color. If it is fake or gold-plated, you may notice discoloration or fading.

Clean and Polish

Use a clean, soft cloth to wipe away any residue from the toothpaste. Polish the gold item to restore its shine.

Part 2: Alternative Home Testing Methods

While the toothpaste method is often considered a simple home test, there are other methods you can use to assess the authenticity of gold:

1. Magnet Test:

Genuine gold is not magnetic. You can use a strong magnet to check if your gold item is attracted to it. If it is, the item may be fake or have a significant amount of other metals mixed with the gold.

2. Acid Test:

Acid testing kits, available online or from jewelry supply stores, contain different acids for testing various karats of gold. Follow the kit’s instructions to apply a small amount of acid to your gold item. A genuine gold item will not react or dissolve.

3. Density Test:

Gold has a specific density, and you can perform a density test at home using water. Fill a container with water and measure its weight. Then, carefully lower your gold item into the water and measure the increase in weight. Gold should be denser than most other materials and displace a certain amount of water based on its volume.
