Amber Vest POWDER
Store at 18-25°C.
Keep the packages tightly closed in a dry place.
The investment is sensitive to moisture: prolonged exposure to the air may alter the
characteristics of the product.
EXPANSOR-B LIQUID
Store at 18-25°C.
Prolonged exposure to temperatures lower than 5°C or higher than 35°C may produce freezing
and/or destabilisation of the product.
Do not use the liquid if it shows a sign of cristallization.
Keep the bottles tightly closed after each use. Prolonged exposure to the air may cause crystallisation.
Batch number and expiry date are marked on each package.
This material contains silica.
DO NOT INHALE THE POWDER! Continued inhalation of the powder
may cause lung injury (silicosis or cancer).
During handling, avoid the formation of powder. Avoid inhalation by using a suitable dust mask.
Eliminate any spillages of powder with a damp cloth.
Avoid the formation of powder during deflasking by submerging the cylinder completely cold in
water. Extract the ammoniac vapours from preheating and emit them to the exterior.
Avoid skin contact with the mixing liquid EXPANSOR. In the event of contact, wash with soap
and water. In the event of contact with the eyes, wash under abundant running cold water and
consult a doctor.

STORAGE AND EXPIRY
SAFETY INSTRUCTIONS

DESCRIPTION
Amber®Vest is an ultra fine, graphite-free, phosphate bound investment for casting press ceramics with
the technique of NORMAL OR QUICK HEATING.
According to ISO 15912:2006, the classification of the product is Type 1 Class 2.
INSTRUCTIONS OF USE
1. LIQUID PREPARATION:
DO NOT USE EXPANSOR LIQUID WHICH HAS BEEN FROZEN (BECOME CRYSTALLISED).
WARNING:
DO NOT USE BOWLS NEITHER
CONTAINERS WHICH HAVE BEEN
IN CONTACT WITH PLASTER.
As with all phosphatic coatings, the temperature of storage and preparation of the coating and of the mixing liquid is
a determining factor in the expansion during setting, and therefore in the precision of fit and the cast surface.
The optimum preparation temperature is 20-22°C. Any variation in the optimum working temperature, whether of
the powder, liquid or mixing utensils, or significant variations in the ambient temperature, affect the behavior
of the product.
2. PREPARATION OF THE CYLINDER
Metal ring and plastic or silicone cylinders can be used.
For 9x cylinders, use always metal ring.
• WITH metal ring:
- Cover the inner part of the cylinder with a quartz band (for example RING-O-LINER).
(1 layer for 1x and 3x cylinders / 2 layers for 6x and 9x)
- Moisten slightly with water the band to prevent the absorption of the investment.
• WITHOUT ring (plastic or silicone cylinder, for example RING-O-EXPAND Press):
Apply a fine layer of Vaseline to facilitate subsequent extraction.
• To obtain good results, it is essential to use the precise measurements.
• For greater ease of use, Amber®Vest is supplied in pre-dosed sachets of 100g,
and a dosing tube is supplied for the liquid.
• It is recommended always to use whole sachets and to measure the liquid with the original
dosing tube.
• In the case of using non-pre-dosed portions of powder, weigh the exact contents with a scale.
The powder-liquid proportion is: 100g powder/25ml liquid:
3. PREPARATION FOR MIXING
Concentrations of the mixing liquid: 70 % EXPANSOR-B + 30 % DISTILLED WATER
CYLINDER SIZE POWDER MIXING LIQUID
1 x 100 g 25 ml
3 x 200 g 50 ml
6 x 300 g 100 ml
4. MIXING
• Prepare the mixing liquid (EXPANSOR-B + distilled water).
• Add the powder to the liquid and mix briskly by hand for 15-20 seconds to obtain
a totally moist and uniform mass.
• Then pass to mechanical vacuum mixing for 60 seconds depending on the mixer.
7. HEATING
• Few minutes before placing in the furnace, scrape with a knife the upper surface
of the cylinder to allow the gases to escape.
• Place the cylinders in the furnace with the spouts downwards.
• In the case of multiple cylinders, also avoid any contact between them.
• Due to the aggressive elimination of the wax, do not open the furnace while heating.
Heating can be carried out in two different ways:
PLACING IN THE FURNACE
5. FILLING THE CYLINDER
Amber®Vest flows over wax surfaces without the need to paint them with degreasing
agents. We recommend the application of a thin layer of TENSIO-WAX over the wax cast
before the coating. When the mixing time is completed, fill the cylinder, vibrating gently,
for 10-15 seconds, then stop.
6. WORKING TIME
7-8 minutes (20-22°C) from the moment that powder and liquid contact.
• The working time can be reduced when the liquid is at a higher temperature.
• With ambient temperatures above 22°C.
• With the use of contaminated utensils.
HEATING
After the mixing, place the cylinder in the furnace for 20-30
minutes at the final casting temperature.
900℃
Fast heating:
• Place the cylinder in the furnace after the setting.
• Dry at 250°C for 40 minutes.
• Heat up at 7°C / min. to the casting temperature.

WARNING:
Wax ignition can lead to
breakings. Place the cylinders
inclined or over investment
plates. Never place them
directly on the oven base.
IMPORTANT: Amber®Vest must be always used with the special liquid
EXPANSOR-B and distillated water. The dilutions can be effected by adding
distilled or demineralised water, shaking slightly and then applying to the bottle
an identifying label of the concentration made.
