Wax = molecular
Candy = molecular (sugar molecules)
Plastic = molecular if it's thermoplastic like polyethylene; network if it's thermosetting like Bakelite
Lead, Aluminum, Copper = metallic
Halite = ionic
Quartz (silicon dioxide), Corundum (silicon carbide) = network
Marble = ionic (calcium carbonate)
