DIY Fused Glass | Microwave Kiln
Fusing glass at home might sound like a professional-level endeavour, but with a microwave kiln, it's actually quite accessible and fun!
If you’re into DIY crafts or just want to try something new, a microwave kiln offers a straightforward and safe way to create beautiful fused glass pieces right in your kitchen. Here's a comprehensive guide on how to get started, including the materials you’ll need, the process itself, and some handy tips.
What you need to get started
First things first, gather your materials. Here’s a list of essentials:
Microwave kiln: The star of the show. These are small, portable kilns that fit into a standard microwave.
Glass sheets or pieces: You can use pre-cut glass pieces or cut your own.
Kiln paper: To line the base of the kiln and prevent the glass from sticking.
Gloves: Heat-resistant gloves to protect your hands.
Safety goggles: Essential for eye protection.
Glass cutter: For cutting your glass pieces to the desired shape and size.
Microwave: A standard household microwave, ideally dedicated to kiln use for safety reasons.
Ventilation: Ensure your workspace is well-ventilated.
Preparing your workspace
Before you start, set up a safe and clean workspace. This should be a well-ventilated area, free from any flammable materials. Lay down some newspaper or a protective mat to catch any stray glass bits.
Cutting and arranging your glass
Now, for the fun part—designing your glass pieces! Use a glass cutter to cut your glass sheets into the shapes you desire. Be creative! You can layer different colours and types of glass to create unique patterns and effects. Remember, the glass will melt and fuse together, so think about how the colours will blend.
Lining the kiln
Place a piece of kiln paper inside the base of the microwave kiln. This paper is crucial as it prevents the glass from sticking to the kiln and ruining both your project and the kiln itself.
Loading the kiln
Carefully place your glass pieces on the kiln paper inside the kiln. Make sure they are centred and not touching the sides of the kiln, as this can affect the melting process.
Put on your safety goggles and gloves. Place the kiln inside the microwave, making sure it’s positioned in the centre. Set your microwave to its highest setting. The firing time can vary, but a general guideline is 3 to 5 minutes. However, always keep an eye on your project! It’s crucial to monitor the process closely, as the glass can melt quickly.
Cooling down
Once your glass has fused to your satisfaction, carefully remove the kiln from the microwave using your heat-resistant gloves. Place it on a heat-resistant surface and let it cool completely. Do not open the kiln until it’s fully cooled down, which can take around 30 minutes to an hour. Opening it too soon can cause thermal shock, leading to cracked or broken glass.
Finishing Touches
After your piece has cooled, remove it from the kiln and gently peel off the kiln paper. If there are any rough edges, you can smooth them with a glass file or a bit of sandpaper and water.
Tips & tricks
Experiment with different glass: Different types of glass melt at different rates. Experiment with various types to see what effects you can achieve.
Layering: Layering different colours and types of glass can create stunning effects. Play around with different combinations to find what you like best.
Microwave power: Microwaves can vary in power, so the firing time may need to be adjusted. Start with shorter times and increase gradually.
Safety first: Always wear safety goggles and heat-resistant gloves. Ensure your workspace is well-ventilated.
Troubleshooting
Uneven melting: If your glass isn’t melting evenly, it might be due to uneven placement or varying thicknesses of glass. Make sure your pieces are of similar thickness and well centred in the kiln.
Cracks or breaks: This often happens due to thermal shock. Ensure your kiln cools down completely before opening, and avoid drastic temperature changes.
Final thoughts
Using a microwave kiln to fuse glass is a fantastic way to dive into the world of glass art without the need for expensive equipment or a professional studio. It’s an accessible and rewarding hobby that allows for endless creativity. Whether you’re making jewellery, decorative pieces, or simply experimenting with glass, the possibilities are vast.
So, why not give it a go? Grab a microwave kiln, gather your materials, and start creating your own beautiful fused glass art. Happy crafting!
