Conical alumina crucibles have a tapered wall — wider at the rim, narrower at the base — which makes pouring and sample recovery easier and helps the crucible release cleanly after firing.

Labmina offers conical crucibles from 3ml to 1500ml in 99% high-purity alumina, with and without covers, all rated to 1600°C. The tapered form is a popular choice for melt work, flux fusion and applications where the contents need to be poured or tipped out.
