Sucrose, table sugar, is a odorless, colorless crystalline powder.

Sucrose melts and decomposes at 186°C to form caramel, and when burnt produces carbon dioxide and water.

Density is 1.587g/mL
Refractive Index is 1.5376

Yes, melting does not alter the chemical nature of the material, it just changes the physical state (solid ---> liquid). For instance, if you heat sodium chloride (common table salt) to 800.7°C, it will melt. If you took that molten salt, and cooled it down, it would recrystallize. But the chemical nature of the sodium chloride would not have changed, though it might not be in the same fine crystals as when you started. However, there are some materials that will decompose upon heating, before reaching their melting point. You can look up the melting points of most chemicals in standard reference manuals such as the CRC Handbook of Chemistry & Physics, the Merck Index, in Material Safety Data Sheets, and in a variety of online references. They will also list the information if the compound decomposes before melting or boiling.
