This Vita Vacumat 250 is a porcelain furnace intended for use in dental applications, but I am inclined to think you could use it to fire other tiny porcelain treasures. We did not run a comprehensive test in house, but this did turn on, light up & the platform raised and lowered without a hitch. There's a bit of damage on the edge of the platform, not sure if that impacts functionality. This is a real oddball, priced accordingly.
