Step 3: Look for Labels or Symbols
Flip the item over or look inside—many objects are marked.
Look for:
- Material codes: Like “PP” for polypropylene or “304” for stainless steel.
- Recycling symbols: A triangle with a number inside (1–7 for plastics).
- Text: “100% cotton,” “Made in China,” “BPA-free,” etc.
Step 4: Smell the Item (If Safe!)
Some materials have a distinct odor:
- Plastic often smells like chemicals or petroleum.
- Leather smells rich and organic.
- Wood has a dry, natural scent.
⚠️ Don’t sniff unknown powders, liquids, or electronics.
Step 5: Perform a Simple Test
With caution, you can do light tests:
- Magnet test: Use a fridge magnet. It sticks to iron or steel but not to aluminum or plastic.
- Scratch test: Lightly scratch a hidden part with a coin. Does it dent, flake, or stay the same?
- Water test: For textiles or wood—does it absorb water or repel it?
Step 6: Research the Item or Brand
If the item has a brand or product name, look it up online. Manufacturers often list the materials in product descriptions or specifications.
Use Google search, or reverse image tools to find more details.
Search like this:
“What is [brand/model] phone case made of?”
“Material of IKEA Bekvam stool”
Step 7: Ask an Expert or Community
When in doubt:
- Ask in hardware stores (for building materials).
- Post in online forums (Reddit, DIY sites).
- Take it to a jeweler (for metal), or a lab (for precise testing).
