Product Overview

Hardin HD-234 CR3KG High Purity 3 KG Graphite Crucible For Hardin-234 Melting Furnace.

This is our Hardin 3 kilogram high purity graphite crucible. This crucible is by far our most common crucible sold individually or in a furnace kit. It is used to hold your precious metals such as silver, gold, and copper while they are melted at high temperatures needed in order to cast into bars and ingots.

Has a little groove at the top to easily grab with tongs. It's recommended that you never fill the crucible to more than a 2/3 to avoid spillage.

This crucible can be used multiple times when handled with care. Oil from your hands will speed the corrosion process after heated. Flux also shortens the life span.
