The following automatic conversions were performed:

'_chemical_melting_point' tag was changed to
'_chemical_melting_point_gt' since the value was specified as 'more
than' ('>') a certain temperature. The value '>300 \%C' was changed
to '573.15' - it was converted from degrees Celsius(C) to Kelvins(K).
