Since every metal/alloy needs special melting conditions, Zircar is having different quality of crucibles for each and every application on the basis of following:
|1||Copper / Brass||Oil / Gas / Coke|
|2||Aluminum||Oil / Gas / Elec. / Coke|
|3||Cast Iron||Oil / Gas / Coke|
|4||Gold / Silver||Oil / Gas / Elec.|
|5||Zinc Oxide||Oil / Gas|
Each and every crucible is suitably glazed to protect the body from oxidation. Glaze is in situ and superficial on the body.
Extra light glaze is applied for Electric furnace melting of Aluminum since oxidation is normally very high at this temperature range.
