Why Witches Cover Their Crystal Balls: The Surprisingly Practical Reason

There are some pieces of witchcraft wisdom that sound wonderfully mysterious when you first hear them. Keep your protective herbs close. Never leave your tools unattended. And, whatever you do, always cover your crystal ball when you’re not using it.

Naturally, a young witch might wonder why.

Will spirits come through? Could something unwanted enter the room? Is there a mysterious energy lurking inside the crystal ball, waiting for an opportunity to escape?

As it turns out, the answer might be considerably more practical than you imagined.

When our CEO was just 14 years old, her grandmother gave her a crystal ball. Along with this very special gift came a rather important instruction.

“When you’re not using the crystal ball, you must always keep it covered.”

Understandably, she wanted to know why. Was it to keep spirits away? Was there a risk of something rather more sinister making its way through the glass?

Her grandmother’s answer was wonderfully straightforward.

“No. It’s made of glass. If the sun hits it in a particular strong direction, strong enough, it’ll burn the whole house down.”

And there it is. No demons, no wandering spirits, no supernatural mischief. Just the sun, a glass sphere and a very sensible piece of advice.

It’s a story that captures something we absolutely love about witchcraft. Sometimes, what sounds mysterious or otherworldly on the surface is actually rooted in intensely practical knowledge.

So, let’s explore why witches cover their crystal balls, what can happen when sunlight meets glass, and how to look after one of the most beautiful tools in the witch’s collection.

Why Do Witches Cover Their Crystal Balls?

The traditional practice of covering a crystal ball when it isn’t being used has several explanations in modern witchcraft. Some practitioners cover their crystal balls to protect them from dust, scratches, unwanted attention or environmental influences. Others associate the covering with keeping the tool’s energy undisturbed between readings.

But there is another reason, and it’s one every crystal ball owner should know.

A glass sphere can concentrate sunlight, potentially creating enough heat to ignite nearby flammable materials.

This isn’t an imaginary danger or an old superstition. Fire services have documented real incidents involving glass ornaments, crystal balls and other curved reflective objects.

In January 2024, Essex County Fire and Rescue Service attended a house fire after sunlight reflecting off a glass crystal ball ornament set fire to a pile of towels. Fortunately, the occupant heard the smoke alarm and extinguished the fire before it could spread.

So, your grandmother wasn’t being dramatic. She was giving you genuinely valuable advice.

How Can a Crystal Ball Start a Fire?

It all comes down to the way light behaves when it passes through a curved glass surface.

A crystal ball is essentially a sphere. Depending on its shape, material and position, it can act like a lens, bending and concentrating sunlight into a smaller area.

Think about how a magnifying glass works. When you hold one in the sunlight and position it correctly, the lens focuses the sun’s rays onto a tiny point. That concentrated energy produces heat.

A glass sphere can create a similar effect.

If the sunlight passes through or reflects off the sphere at just the right angle, it can concentrate energy onto a nearby surface. If that surface is something combustible, such as paper, fabric, curtains or bedding, the concentrated heat can potentially cause scorching, smouldering or ignition.

It’s a phenomenon sometimes called focused sunlight ignition.

The risk depends on several factors, including the shape and optical properties of the object, the strength and angle of the sunlight, and the material receiving the concentrated light. It is not something that happens every time sunlight touches glass, but it is a risk worth taking seriously.

And here’s the part that might surprise you: it doesn’t have to be a blazing hot summer afternoon.

Fire services have warned that sunlight can cause this type of incident throughout the year, including during cooler months when the sun sits at a different angle in the sky.

In other words, your crystal ball doesn’t need to be sitting in the middle of a summer heatwave to deserve a little care.

Why Covering Your Crystal Ball Matters

Covering your crystal ball when you’re not using it is a simple habit that can help protect both your magical tool and your home.

A suitable cover can help prevent direct sunlight from passing through the sphere, while also protecting its surface from dust and accidental scratches.

However, covering your crystal ball shouldn’t be your only safety measure.

The most important thing is to choose a safe place to keep it.

1. Keep it away from direct sunlight

Avoid placing your crystal ball on a windowsill, beside a sunny window or anywhere direct sunlight can fall on it.

Remember that sunlight moves throughout the day. A spot that seems perfectly safe in the morning might be in direct sunlight by the afternoon.

Take a moment to observe how the light travels through your home before choosing a permanent place for your crystal ball.

2. Use an opaque covering

When your crystal ball isn’t in use, place a cloth or purpose-made cover over it.

Choose a fabric that blocks light rather than a sheer or translucent material. A beautiful velvet cloth is a lovely option, and it has the added benefit of creating a soft, protective layer around your treasured tool.

Just remember that a cover is an extra precaution, not a substitute for keeping the crystal ball away from direct sunlight.

3. Store it somewhere secure

A crystal ball deserves a safe resting place.

Choose a stable shelf, cupboard or dedicated storage box away from windows and other sources of direct sunlight. Make sure it cannot easily roll, fall or be knocked onto the floor.

If your crystal ball is particularly heavy, check that the shelf or surface is strong enough to support it.

4. Be mindful of other glass objects

This advice doesn’t apply only to crystal balls.

Glass spheres, decorative crystal ornaments, magnifying mirrors, fishbowls and other curved glass objects can also concentrate sunlight under the right conditions.

It’s worth checking your home for objects that might be sitting in direct sunlight, particularly near curtains, bedding, paper or other combustible materials.

Caring for Your Crystal Ball Beyond the Cover

Of course, protecting your crystal ball from sunlight is only one part of looking after it.

Whether you use yours for scrying, meditation, divination or simply as a beautiful centrepiece on your altar, a little care will help keep it in good condition.

Clean it gently. Use a soft, lint-free cloth to remove dust and fingerprints. If you need to clean the surface, check the manufacturer’s care instructions first, particularly if your crystal ball is made from natural stone or has a special coating.

Handle it carefully. Crystal balls can be surprisingly heavy, and even a small drop can cause damage. Hold yours securely with both hands when moving it.

Give it a dedicated resting place. A padded stand or stable display base can help prevent rolling, scratching and accidental damage.

Keep it covered between readings. This is a lovely way to make caring for your tool part of your regular magical practice. Once your reading is complete, clean the surface if necessary, return the ball to its stand and place its cover over it.

You might even choose a special cloth that you use only for your crystal ball. It doesn’t need to be elaborate or expensive. What matters is that it serves its purpose and becomes part of the care you give to your magical tools.

A Little Witchcraft Wisdom Goes a Long Way

One of the things we love most about witchcraft is the way practical knowledge and magical meaning can sit comfortably side by side.

A crystal ball might be a tool for exploring intuition, working with symbols, practising scrying or connecting with your own inner wisdom. You might associate it with mystery, possibility and the unseen.

But it is also a sphere of glass or crystal sitting in your home.

And sometimes, the most important magical instruction isn’t about casting a spell, calling upon a spirit or protecting yourself from an unwanted presence.

Sometimes it’s simply about remembering to put the cover back on.

There is a beautiful lesson in our CEO’s grandmother passing down this piece of wisdom. She didn’t need to make it frightening or surround it with elaborate explanations. She simply shared what she knew, giving a young witch a habit that would protect her for years to come.

Perhaps that’s one of the most valuable forms of witchcraft wisdom there is: knowing when something needs a little magic, and knowing when it simply needs common sense.

So, the next time you finish a crystal ball reading, remember to cover your beautiful sphere and put it somewhere safe, away from direct sunlight.

Your grandmother would be proud.

Frequently Asked Questions About Covering Crystal Balls

Why do witches cover crystal balls?

Witches cover crystal balls for several reasons. A cover can protect the surface from dust and scratches, and some practitioners believe it helps keep the tool’s energy undisturbed between readings. Importantly, covering a glass sphere can also help prevent sunlight from passing through it and potentially creating a fire hazard. The ball should still be stored away from direct sunlight.

Can a crystal ball really start a fire?

Yes. A glass sphere can act like a lens and concentrate sunlight onto a small area. Under the right conditions, this can generate enough heat to ignite nearby combustible materials. Fire services have documented incidents in which sunlight concentrated by glass ornaments and crystal ball decorations has caused fires.

Should I keep my crystal ball out of sunlight?

Yes. The safest approach is to keep your crystal ball away from direct sunlight, particularly near windows, where the sun’s position changes throughout the day. Covering it when it isn’t in use provides an additional precaution.

What should I use to cover my crystal ball?

An opaque cloth that blocks light is a good choice. Velvet, cotton or another suitable fabric can work beautifully. You can also purchase purpose-made crystal ball covers. Choose something soft enough to protect the surface, and make sure the crystal ball is stored somewhere stable and out of direct sunlight.

Does covering a crystal ball protect it from spirits?

Some witchcraft traditions and individual practitioners associate covering divination tools with keeping their energy undisturbed or protecting them between uses. However, there is no need to assume that an uncovered crystal ball will invite spirits or unwanted entities into your home. The practical safety reason for covering a glass sphere is well established, and it is a very good reason to make the habit part of your routine.

Final Thoughts

Witchcraft is full of traditions, rituals and pieces of wisdom that have been passed from one practitioner to another. Some have spiritual significance, some have practical origins, and some beautifully combine the two.

The instruction to cover your crystal ball is a perfect example.

So, whether your crystal ball is a treasured family heirloom, a much-loved divination tool or a beautiful new addition to your altar, give it the care it deserves.

Keep it away from direct sunlight, cover it when you’re finished, and remember that sometimes the best protection spell is simply a sensible habit.
