Sand Moulding Workshop

Date: Saturday, May 4th 2024
Location: Art Aggregate, 637 Parkdale Ave N, Hamilton, ON L8H 5Z1

Maximum 10 people/workshop
Objects to be moulded should be made out of hard surfaces materials because you do not want
to be picking sand out of your wax positive. Simple shapes are recommended. Think, could I make a simple plaster piece mould of my object? If not then leave that object at home and
bring another. For the sand mould is a simple mould but with material complications.
Please keep in mind that one cubic foot (.028 cubic meter) of sand weights 100lbs (45.36 kilos) and you will be responsible for moving it. There is an option to store the mould at Art Aggregate until the June 8th pour. You can also take the mould home and store it in a dry /cool location. The basic amount of sand you need to be around your object is about 3” (10.16 cm).

The size of the piece/object to be moulded should be around the size of your head give or take.
