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

Question

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

Thanks

Steve

IDK...I used contact cement successfully on most plastics.
