Can You Use Recycled Glass For Candles?

Candle making is a fun and creative hobby that allows you to make personalized decorative candles out of different materials. Recycled glass is one unique and sustainable material that can be used to make beautiful and eco-friendly candles. But is recycled glass safe and effective for candle making? In this article, we will explore the pros and cons of using recycled glass for candles and provide tips on how to make your own recycled glass candles safely.

Pros of Using Recycled Glass

Using recycled glass for DIY candles offers some great benefits. Most notably, it provides a sustainable and eco-friendly way to repurpose waste glass that would otherwise end up in a landfill. Recycling glass into candle holders gives it new life and keeps it out of the waste stream. Upcycling used glass into decorative candles is also a creative way to reuse a material that’s typically discarded.

Another advantage of recycled glass candles is the interesting colors and textures they can provide. Since the glass comes from recycled bottles and jars, it contains an assortment of green, brown, blue, and clear shards. This diversity of colors and imperfect shapes gives each candle its own unique character. The varied glass fragments reflect and refract light in intriguing ways when a candle is lit inside. So recycled glass holders can add beautiful ambience to any space.

Cons of Using Recycled Glass

There are a few potential downsides to consider when making candles from recycled glass:

May have sharp edges. Since the glass comes from recycled sources like bottles, there’s a chance some pieces may have rough or sharp edges that could pose a safety risk and make candle making more difficult.

Tricky to find uniform pieces. When working with recycled glass, it’s challenging to find pieces that are the same size, thickness, and color. This lack of uniformity can impact the aesthetic look of finished candles.

Can be more expensive. Buying recycled glass from specialty shops tends to cost more than purchasing new glass. There’s additional labor involved with sorting, cleaning, and preparing the recycled glass prior to candle making as well.

Making Recycled Glass Candles

Making candles from recycled glass is an eco-friendly craft that takes just a few basic supplies and steps.

To start, gather clean recycled glass pieces of different colors and sizes. Good sources are old glassware, bottles, jars, and vases. Be sure to remove any paper labels. Then decide what size and shape vessel you want your candle to fill like a glass jar or metal tin. Make sure to clean the vessel thoroughly before using.

Prepare the wick by cutting it about 1/2 an inch taller than the height of the vessel so it doesn’t burn inside the melted wax. Secure the wick to the bottom of the vessel with hot glue or adhesive before pouring in the glass and wax.

For the candle wax, soy or beeswax are good eco-friendly options. Break wax into small chunks or beads to melt it faster using a double boiler. Once melted, add about 2 ounces of fragrance oil if desired. Then carefully pour the wax into the vessel around the glass pieces and wick until nearly full. Allow to fully harden before lighting.

Safety Precautions

When working with recycled glass for candles, take safety precautions such as:

• Carefully handle broken glass pieces to avoid cuts. Use thick gloves when sorting through glass.
• Smooth any sharp edges on glass pieces by lightly filing or sanding them.
• Check finished glass candle containers for shards or loose pieces and remove them.

Supervise children closely whenever handling recycled glass. Only allow older children to assist in handling glass under adult guidance. Keep small children and pets away from work areas with broken glass.

Take care when lighting glass candles as the glass may conduct heat. Let candles fully cool before touching glass containers to avoid burns.

Work on a protected surface and carefully clean up any broken glass pieces when done.

Creative Designs

Using recycled glass opens up endless possibilities for unique candle designs. The varied colors, shapes, and textures of recycled glass provide the perfect canvas for creativity.

Layered Colors

Fill your candle jar with layers of different colored glass to create a rainbow or ombre effect. Blues, greens, browns, and clears layered on top of each other produce beautiful gradients when the candle is lit. Add glitter or other embellishments between the layers for more visual interest.

Mixed Shapes and Textures

Instead of using uniformly shaped glass, create contrast and texture by mixing glass pebbles, beads, marbles, and broken shards. The random shapes and uneven surface catches and reflects light in an interesting way when the candle is burning.

Embedding Objects

Customize your candles by embedding small objects in the melted wax like seashells, coins, flowers, and more before it hardens. This adds personalization and a fun surprise inside the candle. Or press objects like flowers or leaves into the glass before pouring the wax to create imprints. Let your imagination run wild!

Gift Potential

Using recycled glass to make candles creates a unique homemade gift that shows creativity and care for the environment. These candles allow for customization with different glass colors and scents to personalize them for the gift recipient. Their one-of-a-kind nature makes them a great conversation starter when received as a gift.

You can shape and color the recycled glass specifically based on the individual you’re gifting it to. Mixing and matching different hues of recycled glass shards allows self-expression. The melted and smoothed edges create intrigue. When lit, the flickering light through the unique glass makes for a beautiful centerpiece gift.

Unlike store bought candles, these homemade recycled glass candles stimulate discussion. Recipients appreciate the effort that went into shaping and personalizing the candle. The eco-consciousness and creativity put into upcycling glass into a candle makes it a gift that stands out. When burned it serves as a talking point, spreading awareness on glass recycling.

Environmental Impact

Using recycled glass for DIY candles can have a positive environmental impact in a couple key ways:

Repurposing waste – Recycling glass reduces the amount that gets sent to landfills. Glass is infinitely recyclable without any loss in quality or purity. Repurposing used glass jars, bottles, and other containers into candles gives them renewed purpose instead of being tossed out.

Reducing new materials needed – Making candles from recycled glass means fewer new raw materials like sand have to be sourced and transported to manufacture new glass. Using post-consumer waste cuts down the energy demands of glass production. This lightens the environmental footprint of manufacturing candle jars.

Cost Analysis

One benefit of making your own candles from recycled glass is potentially saving money compared to buying pre-made candles. However, the cost savings depends on several factors:

Price of Supplies vs Ready-Made Candles

You’ll need to purchase wax, wicks, fragrance oils, jars/containers, and any additional candle making supplies. The more elaborate the container, the more expensive your raw materials may be. Simple mason jars and recycled glass containers tend to be cheaper. You’ll also need to account for the cost of tools like a scale, thermometer, double boiler pot, etc.

In contrast, ready-made candles can range greatly in price from a few dollars to over $50+ depending on size, container material, brand name, where they are sold, etc. Making your own with recycled containers can result in noticeable savings.

Time Investment

Additionally, consider the time investment required to make candles versus just purchasing ready-made ones. It takes trial and error to master proper wax heating, container preparation, wick size, candle safety, and more. If your time is valuable, make sure to weigh whether homemade candle expenses + effort is worthwhile compared to store-bought.

Conclusion

As we have seen, using recycled glass for candles has several notable benefits but also some drawbacks to consider. On the plus side, recycled glass candles utilize waste materials that would otherwise end up in landfills. The irregular shapes can create unique candle holders with artistic value. Glass candles can also be safe if proper precautions are followed, such as using heat-resistant containers, wicks, and wax.

On the other hand, glass edges can be sharp and potentially dangerous if handled improperly. Recycled glass tends to have imperfections that reduce its clarity, which some people find less attractive for candles. And the melt temperature can make spilled wax more difficult to clean. Overall, recycled glass candles offer creative reuse potential but require safety awareness during production and use.
