Questions worth asking
Are silicone molds eco friendly?
Silicone is more eco friendly than single use plastic because it is durable and reusable. However, it is not biodegradable. Look for silicone made from recycled or plant based sources for a lower impact.
Can I use eco friendly molds with resin?
Yes, silicone molds are ideal for resin because resin does not stick to silicone. Ensure the mold is food grade silicone to avoid any chemical reactions.
What is the best material for metal casting?
For low temperature metals like pewter, a natural rubber mold is best. It can withstand heat up to 150°C. For higher temperatures, you need a metal mold, but those are not eco friendly.
How long do eco friendly molds last?
With proper care, silicone molds can last for years, even hundreds of casts. Natural rubber also lasts long if not exposed to extreme heat. Recycled plastic is durable but may become brittle over time.
Are plant based silicone molds truly compostable?
Only if they are certified compostable, like those labeled with BPI or TUV. They require industrial composting conditions to break down. Home composting may not be hot enough.
Can I use a regular silicone mold and still be eco friendly?
Yes, because reusing any mold reduces waste. Choose high quality silicone that lasts longer. Some companies use recycled silicone, which is even better.
Do eco friendly molds cost more?
Often they are slightly more expensive due to sustainable sourcing. However, they are durable and can save money in the long run because you don’t need to replace them as often.
How do I clean eco friendly molds?
Wash with warm soapy water and dry thoroughly. Avoid using abrasive scrubbers. For resin residue, soak in warm water before cleaning.
The bottom line
For most crafters, the Eco-Mold Silicone Jewelry Mold Kit is the best choice due to its balance of safety, durability, and environmental friendliness. If you cast metal, choose the GreenCraft Recycled Rubber Mold. For budget conscious beginners, the ReMold Recycled Silicone Mold offers great value.
