I think about three thousand Celsius is the practical limit, and that is with atmosphere control. The semiconductor manufacturers use crucibles etc. of pure iridium. You gotta believe those cost an arm, a leg and buyer's choice of an endocrine gland. Iridium melts 2450, and silicon freezes at 1410. Those boys know their atmosphere control.
Much above 2000 Celsius and you're in just-hanging-on territory. Materials lose strength and toughness. A lamp filament runs 3100 or so, but it is just sitting there, not doing any duty except Being Friggen Hot. And even then, you get the occasional, familiar Blue Flash of Lost Patience. *pop*
