Universal Phosphate Investment for All Crown and Bridge Alloys
FastFire 15 is a ne-grain phosphate
investment which requires only a
15-minute benchset before placing

burnout. It produces accurate,
smooth castings using either the
ringless or metal ring technique.
Optimum t is achieved for all crown
and bridge alloys through dilution of
the freeze stable FastFire Liquid.
Features:
• Produces castings in less than one
hour
• FastFire Liquid allows year
round, problem-free shipping and
controlled expansion
• Reliable performance using many
casting techniques and alloys
• Exceptionally smooth, accurate
castings
