Making a flat-back one-piece block mould, demonstrates many of the basic techniques needed to handle silicone mould making.
Silicone can handle the reproduction of high detail, the capturing of texture and form and the release of pieces with undercuts.

The Model
Pick a model that has a flat back such as a plaque. It can be made from virtually any material, wax, non-hardening oil based clay, leather, hard water based clay, concrete, metal or plaster to name

Equipment required
For mixing large amounts of CraftSil 750, an accurate set of scales will be required. Other items that will be required include:
CraftSil 750 (2 part pack)
Eye Goggles
Latex Gloves
Sealer
Disposable stirring sticks
Conical measure for catalyst
Plastelina
Mould box material: Wood, Lego blocks or Corflute.
Conical measure for catalyst if mixing small amounts. Use scales for all larger moulds.
Model Preparation
Fasten your model to the mould box base using a hot glue gun, running a thin bead around the base of the model, a few millimetres in from the edge. Latex may also be used. Simply put a dab in the centre of the model.
Adhere the model to the centre of the box base by applying light pressure. A gap of 6mm between the model and the edge of the box is recommended.

It should be noted that a rolled ribbon of Plastelina pressed around the bottom perimeter of the model works well. The model should be pressed firmly on the base board in all directions. This flattens the clay while at the same time forming a tight seal under the model to prevent rubber from leaking underneath. Remove any Plastelina that is squeezed out past the edge of the model base.
