The discussion centers on finding a safe solvent for dissolving ordinary white crystallized table sugar, with a focus on substances that evaporate and leave sugar as a residue. Methanol is identified as a solvent that can dissolve sugar, but caution is advised due to its potential skin absorption and toxicity if ingested. While methanol can be handled safely with proper precautions, prolonged skin contact can lead to health risks, although such cases are rare. Denatured alcohol, primarily ethanol mixed with toxic substances, is noted to be ineffective for dissolving sugar. Participants express uncertainty about the availability of methanol and clarify the differences between methanol and denatured alcohol.
