A:
Some melting points of common substances, courtesy of
the CRC Handbook of Chemistry and Physics (editor: Weast).

Sand (silicon dioxide, or Quartz): 1723 C

(some sands are mixtures of other materials, like
calcium carbonate, but many sands have quartz in them)

MgF2: 1261 C

Salt (I’ll assume you mean NaCl): 801 C

Sugar (glucose and dextrose have the same
melting points): 146 C

Copper: 1083.4 C
