According to the Handbook of Chemistry and Physics, thorium oxide
melts at 3050 centigrade, within the capability of oxyacetylene. So
melting of a thoria mantle wouldn't prove that their torch is any
hotter than oxyacetylene.

What we need is something that doesn't oxidize at white heat, and
has a melting point higher than an oxyacetylene torch can provide. A
cursory search in the handbook doesn't turn up any oxides of higher
melting point than thoria, so what could be used?
