L3 - Casting Slip School (2 day course)
Tuesday 26 & Wednesday 27 February 2019 - 2 day course
Day 1: Slip Control
With the use of simple viscometers and slip density measurement, control of casting slip and glaze slip properties is achieved.
The module will explain how to:
- Measure and adjust a slip to a required density
- Set up and operate the Torsion and Brookfield Viscometers
- Use viscometers to monitor flocculant and deflocculant additions
- Adjust a casting slip to the required fluid properties.
The practical sessions will allow each participant to carry out the above activities.
At the end of the module, you will be able to:
- Measure and adjust slip density
- Set up and take fluidity/viscosity and thixotropy measurements using the Torsion and Brookfield Viscometers
- Construct a deflocculant demand curve
- Correct the fluid properties of a slip.
Day 2: Casting
Slip casting is the process for producing large complex shaped items and handles.
This module explains:
- The casting mechanism
- How deflocculants affect the casting process
- Optimising body formulations for casting
- Functions and uses of plaster moulds in the casting process
- Casting faults and how to correct them
The practical session will include:
- Casting items from a slip at different levels of deflocculation, to various thicknesses
At the end of the module, you will be able to understand:
- The basis of the casting mechanism
- How deflocculant additions alter casting properties
- The function, pros and cons of using plaster moulds
- The causes of the common plaster faults and how to eliminate them
