Preparation of the Borax Solution
Materials
- Borax powder
- Hot water
- Glass jar or container
- Measuring cups and spoons
- Stirring spoon
Instructions
1. Determine the amount of borax powder to use: The amount of borax powder required will vary depending on the size of your container. A good starting point is 1/2 cup of borax per 1 quart of water.
2. Create a supersaturated borax solution: In a glass jar or container, dissolve the borax powder in hot water until it can no longer be dissolved. A supersaturated solution is when the solution contains more dissolved solute than it can normally hold at a given temperature.
3. Procedure for creating a supersaturated borax solution:
| Step | Description |
|---|---|
| a. | Pour 1 cup of hot water into the glass jar. |
| b. | Add 1/4 cup of borax powder to the water and stir until it dissolves. |
| c. | Repeat step b until the solution can no longer dissolve any more borax powder. |
| d. | Allow the solution to cool to room temperature. |
Supercooling the Solution
Supercooling is a process of cooling a liquid below its freezing point without it solidifying. In the case of borax crystals, we want to create a supersaturated solution of borax in water, which will then form crystals as it cools down and becomes supercooled.
To supercool the solution, we can use a few different methods. One common method is to heat the borax solution to a high temperature, such as 80°C (176°F), and then cool it slowly while stirring constantly. As the solution cools, the borax will start to crystallize out of the solution. However, if we cool the solution too quickly, the crystals will be small and disorganized.
Another method for supercooling the solution is to use a seed crystal. A seed crystal is a small crystal of the desired material that is added to the solution. The seed crystal provides a surface for the borax crystals to grow on, which helps to create larger and more organized crystals.
The following table summarizes the steps for supercooling the borax solution:
| Step | Description |
|---|---|
| 1 | Heat the borax solution to a high temperature (e.g., 80°C). |
| 2 | Cool the solution slowly while stirring constantly. |
| 3 | Add a seed crystal to the solution (optional). |
| 4 | Allow the solution to cool completely. |
Introduction of the Seed Crystal
The seed crystal serves as the foundation for the growth of a larger, more perfect crystal. To obtain a seed crystal, you can either purchase one online or follow these steps:
- Dissolve borax in hot water: Dissolve approximately 1/2 cup of borax powder in 1 cup of hot water. Stir until the borax is completely dissolved.
- Filter the solution: Pour the solution through a coffee filter into a clean glass. This helps remove any impurities that could interfere with crystal growth.
- Crystallize the solution: Tie a string around the middle of a pencil. Suspend the pencil over the glass so that the string hangs vertically in the solution.
- Wait for crystal formation: Cover the glass with a paper towel and let it sit at room temperature for a few days. Small crystals will begin to form on the string.
- Select a seed crystal: Once the crystals on the string have grown to a suitable size, choose the clearest and most well-formed crystal as your seed crystal.
- Carefully remove the string or wire from the supersaturated solution.
- Use a spoon or tweezers to gently lift the crystals out of the solution.
- Place the crystals on a paper towel or a clean cloth to dry.
- Allow the crystals to dry completely before handling them further.

Monitoring Crystal Growth
Once the borax solution has been prepared and the seed crystal has been introduced, it is time to monitor the growth of the crystal.
1. Keep the Solution Saturated
The key to successful crystal growth is to ensure that the solution remains saturated with borax. This means that there should always be a small amount of undissolved borax crystals at the bottom of the container. If the solution becomes too dilute, the crystals will stop growing or may even dissolve.
2. Avoid Agitation
Crystal growth is a delicate process that can be disturbed by even slight vibrations or movements. Once the crystals have started growing, it is important to keep the container as still as possible. Avoid touching or moving the container and尽量 protect it from sources of vibration.
3. Check the Temperature
The temperature of the solution can affect the rate of crystal growth. Higher temperatures generally result in faster growth, but they can also lead to the formation of smaller crystals. For optimal growth, it is best to keep the solution at room temperature or slightly warmer.
4. Observe the Crystal Formation
As the crystals grow, they will change in size and shape. It is important to observe the crystals regularly to track their progress and to identify any problems that may arise. Use a magnifying glass to examine the crystals closely and look for imperfections or signs of damage.
5. Determine the Optimal Growth Period
The optimal growth period for borax crystals can vary depending on the size and shape of the crystals you want to produce. Smaller crystals will grow more quickly than larger crystals, and crystals with complex shapes will take longer to form than simpler shapes. It is important to monitor the crystals closely and remove them from the solution when they have reached the desired size or shape. The following table provides a general guide to the optimal growth period for different types of borax crystals:
| Crystal Size | Optimal Growth Period |
|---|---|
| Small (less than 1 cm) | 1-2 days |
| Medium (1-2 cm) | 3-5 days |
| Large (over 2 cm) | 1-2 weeks |
| Complex Shapes | 2-4 weeks or longer |
Factors Influencing Crystal Morphology
Growth Rate
The growth rate of a crystal influences its morphology. Rapid growth rates can lead to dendritic or skeletal crystals, while slower growth rates allow for the formation of more well-developed crystals with smooth faces.
Temperature
Temperature also affects crystal morphology. Higher temperatures can lead to the formation of smaller and more equant crystals, while lower temperatures favor the growth of larger and more elongated crystals.
Concentration of Reactants
The concentration of reactants in the solution can also influence crystal morphology. Higher concentrations of reactants can lead to the formation of larger and more perfect crystals, while lower concentrations can result in smaller and less well-developed crystals.
Presence of Impurities
The presence of impurities in the solution can affect crystal morphology. Certain impurities can act as growth modifiers, altering the shape and size of the crystals.
Solution pH
The pH of the solution can also influence crystal morphology. Different pH values can favor the growth of different crystal faces, leading to the formation of crystals with varying shapes.
Agitation
Agitation of the solution can affect crystal morphology. Gentle agitation can help promote the formation of larger and more perfect crystals, while vigorous agitation can lead to smaller and less well-developed crystals.
| Factor | Effect on Morphology |
|---|---|
| Growth rate | Rapid: dendritic; Slow: smooth faces |
| Temperature | High: small and equant; Low: large and elongated |
| Concentration | High: larger and perfect; Low: smaller and less developed |
| Impurities | Act as growth modifiers, altering shape and size |
| Solution pH | Favors growth of different crystal faces |
| Agitation | Gentle: larger and perfect; Vigorous: smaller and less developed |
Troubleshooting Crystal Growth Problems
Crystals Are Too Small
Check the temperature of the solution. The ideal temperature for crystal growth is between 25-30°C (77-86°F). If the solution is too cold, crystals will form slowly and may be small or misshapen. If the solution is too hot, the water molecules will evaporate too quickly, leaving behind a concentrated solution that can form small crystals.
Crystals Are Too Large
Large crystals can be formed by allowing the solution to cool slowly over a period of several days or even weeks. The longer the solution takes to cool, the larger the crystals will grow. To slow the cooling process, cover the container with a layer of plastic wrap or place it in a warm, insulated location.
Crystals Are Not Forming
Check the concentration of the solution. The solution should be saturated, meaning that it contains the maximum amount of Borax that it can dissolve. If the solution is not saturated enough, crystals will not form. Add more Borax to the solution and stir until it dissolves completely.
Crystals Are Cloudy or Discolored
Cloudy or discolored crystals can be caused by impurities in the solution. Filter the solution through a coffee filter or a fine sieve to remove any impurities. You can also try using distilled water instead of tap water.
Crystals Are Breaking Apart
Crystals can be fragile and break easily. Handle them with care and do not touch them with your fingers. If a crystal breaks, you can try to glue it back together with super glue or clear nail polish.
Crystals Are Growing On The Sides Of The Container
If crystals are forming on the sides of the container, it means that the solution is too concentrated. Add more water to the solution and stir until it dissolves completely. You can also try using a larger container so that the crystals have more room to grow.
Harvesting Your Crystals
Once your crystals have had time to form, it’s time to harvest them. This should be done carefully to avoid damaging them. Here are the steps for harvesting your crystals:
Preserving Your Crystals
Once your crystals are dry, you may want to preserve them to keep them looking their best. Here are some tips for preserving your crystals:
Store them in a dry place.
Crystals can absorb moisture from the air, which can cause them to dissolve. To prevent this, store your crystals in a dry place, such as a sealed container or a display case.
Protect them from sunlight.
Sunlight can fade the color of crystals over time. To prevent this, store your crystals in a place where they will not be exposed to direct sunlight.
Handle them with care.
Crystals are delicate and can be easily damaged. When handling them, avoid touching them with your bare hands. Instead, use gloves or a soft cloth.
