For centuries, fired clay has been the only material capable to resist to high temperatures.
For centuries, this earth has been chosen, studied, optimised, elaborated… but no one found a better material.

The crucible, an essential part in the dental prosthesis elaborating process.

The process of creating a dental prosthesis requires the use of a crucible.

There are two main types of crucibles:

Crucibles for flame melting:

This type of first generation crucible is very resistant and gives very 
good results. It is now less popular, but is still used by many customers.

Crucibles for induction casting machine:

This newer type of crucible is more widely used. Each machine has its
own customised crucible. Whatever its quality, this crucible is fragile and
can withstand less casting cycles than the flame melting type. Its inevitable
but unpredictable failure has major consequences that all laboratories fear.

The Duo System by Refracto: a significant innovationin the casting process

Either single or double layer, no crucible can ensure a 100% successful casting.

An innovation to eliminate the uncertainty of casting: the DUO SYSTEM: a Holder crucible containing a ceramic Insert in which the alloys is melted…
A simple idea, but also difficult to set up when you have to respect the dimensions and volumes of the tube.
