Can someone provide me any info on how to convey apart different types of plastics that we find around the house?

Such as fan blades, bic lighters, computer casings, toys, trash can, kitchen bowls etc. Most of the time there are no markings. Any info on best ways to repair such items, like weld, or gluing methods also apprciated. I'm contemplating starting a new hobby within the repair field.


Thanks

Steve
