Mould Making

Home » Mould Making

After you have invested many, many hours in wax modelling, you'll want to create a robust mould to withstand the kiln firing process.  Using quality materials is imperative to ensuring a good mould for glass casting.

Mould making products used at Dicastglass Studio. 

  • Dental and Utility Plaster are both used in refractory moulds - each plaster has benefits of use.
  • Silica flour, top quality grade (350) is used with plaster for refractory moulds.
  • Fibreglass is used in our studio as a 'skin' layer to the refractory moulds.
  • Grog is used to add strength to larger refractory moulds.
  • Silicone Rubber is a valuable asset to the casting studio to make replica moulds for pouring multiple waxes.


Bulls-eye Level

LEVEL
LEVEL
The Bulls-eye Surface Level is ideal for levelling the bases of moulds for glass casting.  The bulls-eye level can level in all directions avoiding the need to move the level.  The bulls-eye level has multiple uses in the home, check appliances, level motor-homes and pool tables.

Watch a video on using the bullseye level.

Tip: Place you bullseye level on a piece of window glass a bit bigger than the base of your mould.  Lift the glass and level up onto the mould while the plaster/silica mix is still workable.  Squish the glass down to create a flat surface centering the bubble in the circle.  Remove the glass after the plaster has hardened.

Sculpture Wheel

SWHEEL
SWHEEL
The Sculpture Wheel is a very useful tool for model making, sculpting and modelling. Often referred to as a lazy susan, banding wheel or turntable.

Use the sculpture wheel or turntable to easily rotate your work as your hand build with clay or wax, sculpt and smooth modelling materials.   Carve or decorate evenly as you turn the lazy-susan-style sculpture wheel.

The sculpture wheel has been designed with a low centre of gravity to give stability while you are working.

Watch a video about the Sculpture Wheel.

Di Tocker says "I have been looking for the ideal turntable or lazy susan for sculpting and moulding for many years. I have used products designed for ceramics such as banding wheels, but none came large enough or stable enough for me to make my large moulds on.  I use the sculpture wheel for modelling new forms in wax, and mould on the sculpture wheel every time now.  The turntable really helps with creating even wall thickness on my moulds".

Bat - Acrylic board for mould making

Bat
Bat

Batts are ideal boards to make your moulds for glass casting on.  
Made from 3mm acrylic perspex

Tip: Use the bat on top of the sculpture wheel to mould on.  When you finish one mould, just take it off the sculpture wheel still atop the bat. Place another bat on top of the sculpture wheel to do your next mould.
