This remarkable alloy melts at just 61°C, but does
not contain lead or cadmium. It is relatively hard and extremely tough. It is
used, for example, to fill small tubes for bending without crushing, castings
for models and jewellery, and for making precision moulds. Fields metal makes a
fantastic demonstration of how several constituents, each with a much higher
melting point, can be combined to produce a useable alloy.
Demonstration use is recommended -
Indium is a potentially toxic material if ingested. Before using a risk
assessment should be carried out.
Pack Size: 10g
Volume (when melted): approx. 1.3ml
Field's Metal could be used along with moulds made
from Chromatic Alginate (available separately).
