Crafting with Crystals

What crystals should NOT be put in candle wax?

When using crystals in candle wax, it’s important to choose crystals that are heat-resistant and won’t release harmful chemicals or react negatively with the heat. Here are some crystals that should generally be avoided when putting them in candle wax:

  1. Selenite: Selenite is a very soft crystal and can be affected by the heat of a candle, potentially melting or becoming damaged.
  2. Halite (Salt Crystals): Halite is composed of salt and will readily dissolve in the heat of the melted wax, affecting the appearance and integrity of your crystal.
  3. Lepidolite: Lepidolite contains lithium, which can be sensitive to heat. Using it in candle wax may not be advisable as it could potentially release toxic fumes.
  4. Angelite: Angelite is a form of anhydrite and can absorb moisture from the wax, potentially causing it to become soft or crumble when heated.
  5. Calcite: Some varieties of calcite are sensitive to heat and may lose their luster or become damaged when placed in candle wax.
  6. Azurite: Azurite is sensitive to heat and can become damaged or discolored when exposed to high temperatures.
  7. Kyanite: While kyanite is generally heat-resistant, it’s a good practice to ensure the candle wax doesn’t contain any impurities or chemicals that might react with the crystal.
  8. Hematite: Hematite is generally heat-resistant but can oxidize over time when exposed to open flames, potentially altering its appearance.
  9. Malachite: Malachite is copper-based, and prolonged exposure to heat from a candle could lead to oxidation or other changes in the crystal.

Always research the specific properties of the crystals you plan to use with candles and exercise caution. If you are uncertain about a particular crystal, it’s safer to place it away from the direct flame, embedded in the candle wax, or on top of the solidified wax after the candle has burned. Using a heat-resistant dish or container to hold the crystal near the candle is also a good way to enjoy their energies without risking damage or adverse reactions.

What crystals should NOT be put in water?

While many crystals are safe to place in water, there are some that should be avoided because they can dissolve, become damaged, or release toxic substances when submerged. Here are some crystals that should NOT be put in water:

  1. Selenite: Selenite is a delicate crystal that can easily dissolve in water. It’s best to keep selenite dry to preserve its structure.
  2. Halite (Salt Crystals): Halite is composed of salt, and it will readily dissolve in water, leaving you with a salty solution.
  3. Lepidolite: Lepidolite contains lithium, which can be toxic if ingested in large quantities. Avoid submerging lepidolite in water to prevent the leaching of lithium.
  4. Pyrite (Fool’s Gold): Pyrite can react with water and oxygen to form sulfuric acid, which can damage both the crystal and anything it comes into contact with.
  5. Calcite: Some varieties of calcite are sensitive to water and can easily dissolve or lose their luster when submerged.
  6. Malachite: Malachite is copper-based, and prolonged exposure to water can cause it to oxidize and turn green or develop a powdery surface.
  7. Angelite: Angelite is a form of anhydrite, which can absorb water and become soft or even crumble over time.
  8. Kyanite: Kyanite is relatively water-resistant but can have impurities that may react with water and affect its appearance.
  9. Hematite: Hematite can rust when exposed to water, which can alter its appearance.

Always research the specific properties of the crystals you have to determine if they are safe to put in water. When in doubt, it’s best to use alternative methods, such as placing the crystal near water or using indirect methods like a crystal grid or elixir-making technique that doesn’t involve direct submersion.

What crystals should NOT be put in resin crafts?

Not all crystals are suitable for use in resin crafts, as some can react with the resin or lose their luster when submerged. Here are some crystals that should generally be avoided when making resin crafts:

  1. Selenite: Selenite is a delicate crystal that can easily dissolve or become cloudy when in contact with liquids, including resin.
  2. Halite (Salt Crystals): Halite is composed of salt and will dissolve in liquid, which will affect the appearance and integrity of your resin project.
  3. Lepidolite: Lepidolite contains lithium, which can be sensitive to moisture and may not fare well when embedded in resin.
  4. Azurite: Azurite is sensitive to moisture and can become damaged or discolored when exposed to liquid, including resin.
  5. Angelite: Angelite is a form of anhydrite, which means it can absorb water and become soft or even crumble when placed in resin.
  6. Calcite: Some varieties of calcite are sensitive to moisture and can lose their luster or become damaged when submerged in resin.
  7. Scolecite: Scolecite is another crystal that can become damaged when exposed to liquids, so it’s best to avoid using it in resin crafts.
  8. Kyanite: While kyanite is relatively water-resistant, it may have impurities that react with the resin and affect its appearance.
  9. Hematite: Hematite can rust when exposed to moisture, including the moisture present in uncured resin, which can alter its appearance and potentially affect the resin project.

Always research the specific properties of the crystals you plan to use in resin crafts to ensure they are compatible with resin. When in doubt, choose crystals that are known to be safe for use in resin projects or consider using alternative methods, such as placing the crystals on top of the resin surface or creating a layered effect to prevent direct contact with the resin.
