Made
from seaweed, this remarkable material is used in dentistry to make precision
moulds in the mouth for crown construction etc. It is also the material used
for making casts of body parts, including babies’ hands and feet.
When the fine white powder is mixed with water, it turns purple
and then changes colour to indicate readiness for moulding around a pattern –
and then setting.
It takes just minutes to create a durable flexible mould capable
of taking plaster, plastics and low temperature metals such as Fields metal.
The material is entirely natural and non–toxic, and has a very low cost
compared to other high–definition mould making materials such as silicon
compounds.
