1. A horizontal rotating arc furnace comprising:
a housing defining an interior configured to receive particles for forming quartz or ceramic body and electrodes that generate a plasma arc, the housing including a plurality of first ports on an exterior of the housing fluidly connected to the interior and supply pipes fluidly coupled to the first ports;
supports mechanically coupling the housing to a drive system to provide rotational motion to the housing; and
a rotary union coupled to the housing, the rotary union including second ports to fluidly connect to a vacuum supply, the second ports fluidly connected to at least some of the first ports via the supply pipes,
wherein the horizontal rotating arc furnace is configured to apply a vacuum to the interior of the housing via the first ports when the housing is rotating.
