How to Make Bioplastic Suncatchers
-
Combine Ingredients: In a pot, mix the water and cornstarch. Stir well until the cornstarch is fully dissolved without any lumps. This step is crucial for achieving a smooth and lovely texture!
-
Heat and Thicken: Add glycerin and vinegar to the pot. Heat the mixture over medium heat, stirring continuously until it thickens, which should take about 5-7 minutes. Look for a gooey, glossy consistency.
-
Cool Down: Once thickened, remove the pot from heat and allow the mixture to cool slightly for a few minutes. This makes it easier to handle when adding colors.
-
Color It Up: Divide the thickened mixture into several bowls. Add natural food coloring to each bowl, blending until you achieve your desired vibrant hues. Get creative with combinations!
-
Shape Your Suncatchers: Use cookie cutters or molds to shape your colorful mixture. Place the shaped suncatchers onto a baking sheet lined with parchment paper-this will help prevent sticking.
-
Dry Completely: Allow the suncatchers to dry thoroughly, preferably in a sunny location for enhanced clarity. This process can take a few hours, so be patient; it will be worth it!
Optional: For an extra touch, add a sprinkle of glitter to the mixture before shaping.

-
Drying Tips: Suncatchers should dry completely before storing. Ensure they're fully dried to avoid moisture, which can cause damage.

Reheating Option: If the mixture thickens too much, gently reheat with a splash of water over low heat, stirring until it reaches your desired consistency for another round of crafting.
Make Ahead Options
These Eco-Friendly Cornstarch Suncatchers are perfect for busy home cooks looking to save time without sacrificing creativity!

Eco-Friendly Cornstarch Suncatchers Recipe FAQs
How do I choose the right cornstarch for this recipe?
Absolutely! Look for high-quality cornstarch without any additives. I recommend using a brand that is pure and labeled "cornstarch" to ensure the best results. Avoid products that contain anti-caking agents that could affect the texture of your suncatchers.
How should I store leftover suncatchers?
Very important! Store your fully dried suncatchers in a cool, dry location, preferably in an airtight container, to prevent damage. They can last for several months if kept out of direct sunlight. If you're using them as decorative pieces, a decorative box can also work beautifully!
Can I freeze the cornstarch mixture?
Absolutely! To freeze the leftover cornstarch mixture, pour it into an airtight container or freezer-safe bag. Make sure to label it with the date. The mixture can be frozen for up to 3 months. When you're ready to use it again, let it thaw in the refrigerator overnight, then reheat gently on the stove with a splash of water to regain the desired consistency.
What if my mixture clumps when I cook it?
No worries! If your mixture clumps, it's often due to the cornstarch not being fully dissolved before heating. To troubleshoot, you can try whisking it vigorously to break up the lumps. If it has been heated too much, try adding a tiny bit of water while stirring continuously over low heat until it smooths out again. Remember, patience is key-it may take a bit of work, but you'll get that lovely gooey texture!
Are these suncatchers pet-safe?
Great question! While the main ingredients are non-toxic, it's always best to monitor your pets around crafts. Make sure there are no small parts to ingest, and consider keeping the suncatchers out of reach. If your pet has specific dietary allergies or sensitivities, it's wise to consult your veterinarian before engaging in crafts that might pose a risk.
How can I make my suncatchers shine more?
I recommend adding a bit of glycerin to your mixture! This not only adds shine but also helps retain moisture, making your suncatchers flexible and glossy. Additionally, placing them in direct sunlight while drying will enhance their clarity and brightness, so pick the sunniest window you can find!
