2.1.3 Liquid dilution chart
The liquid dilution chart is designed to help produce the optimal expansion value for your individual
castings and is based upon the type of alloy and size of ring used. This information is contained within
the ‘Instructions for Use’ and is based on extensive laboratory testing in combination with a complete
series of casting trials.For example here is the liquid dilution chart for GC Fujivest Premium.

However because the working methods and equipment can differ between individual dental laboratories
(e.g. waxes, resins, casting liner, mixing equipment, etc.) it is possible that differing end-results may be
obtained requiring slight changes to the stated ratios (see 2.1.4).
All of the fit tests have been carried out on castings using the quick heating method (20 min setting) and
it should be noted that a longer setting time would increase the expansion.
2.1.4 Individual liquid dilution chart
When trying new alloys, alloy manufacturers or
investment materials we suggest that initially you
use the correct ratio as stated in our ‘Instructions
for Use’. It is then possible for you to judge whether
this provides the correct expansion for your needs
or a slight alteration of the dilution is needed.
We also provide a chart that can be used to
indicate the alloy type, type of work and your
personal choice of dilution ratio obtained
following your personal casting experiences.
Here it is very important to consider the information
given in sections 1.5 & 2.1.1.
