We’ll take a closer look at the different types of disappearing ink and what you can do with them.
Chemical Composition of Disappearing Ink
Disappearing ink, also known as vanishing ink, is a type of ink that fades over time or when exposed to heat. The chemical composition of disappearing ink is what makes it unique and enables it to vanish. Traditionally, disappearing ink was made up of water, thymolphthalein, and sodium hydroxide. Thymolphthalein is a pH-sensitive compound that changes color according to whether it is in an acidic or basic environment. Sodium hydroxide, also known as lye, is a strong base that has a high pH level.
- Water: Water is the primary solvent used to dissolve the ink substances and create a uniform solution.
- Thymolphthalein: Thymolphthalein is a pH indicator that is colorless at a neutral pH and changes to blue in the presence of a strong alkaline, such as sodium hydroxide.
- Sodium Hydroxide: Sodium hydroxide is used to increase the pH of the solution and activate the color change of the thymolphthalein. This is what causes the ink to disappear as it reacts with carbon dioxide in the air.
Newer variations of disappearing ink may use different compounds to achieve the same disappearing effect. For instance, some types of disappearing ink use acids instead of bases, which fade when exposed to heat. Others may use organic solvents as the carrier instead of water, allowing the ink to disappear more rapidly. Ultimately, the chemical composition of disappearing ink plays a critical role in determining how long the ink will last and how it will fade.
In summary, disappearing ink is made up of a solvent, a pH indicator, and a base or acid that makes it vanish over time or with heat. The unique chemical composition of disappearing ink is what gives it its ability to disappear and is an essential consideration when looking to purchase a disappearing ink product.
Different types of disappearing ink
Disappearing inks come in different types. They are used for different purposes depending on the nature of the task. Here are some of the different types of disappearing ink:

How to make disappearing ink at home
Disappearing ink can be a fun and creative way to add a little mystery to your writing. It’s a type of ink that appears visible on paper for a short period of time and then fades away completely, leaving no trace behind. Here’s how you can make your own disappearing ink at home:
- Subsection 1: Gather the ingredients
- Lemon juice
- Cotton swabs or brushes
- White paper or notecards
- A heat source such as a candle or light bulb
- Subsection 2: Mix the lemon juice
- Subsection 3: Grab the paper
- Subsection 4: Allow the ink to dry
- Subsection 5: Write with your new ink
- Subsection 6: Reveal the message
