What is the composition of inlay wax?
Dental inlay wax is a mixture of several waxes, usually containing paraffin wax, ceresin wax, beeswax and other natural and synthetic waxes. It is used to prepare patterns for gold or other metallic materials in the fabrication of inlays, crowns and bridges.

What are the properties of wax?
Scientists consider “wax” to be a generic term for classifying materials that have the following characteristics:
- Solid at room temperature; liquid at higher temperatures.
- Primarily hydrocarbon in structure.
- Water repellent; insoluble in water.
- Smooth texture; buffable under slight pressure.
- Low toxicity; low reactivity.
What are the different properties of dental waxes?
PROPERTIES
- Melting range. Composed of molecules of different molecular weight.
- Thermal expansion. They expand upon being heated and shrink when cooled.
- Modulus of elasticity, proportional limit and compressive strength, they are low and temperature dependent.
- Runoff.
- Residual stress.
- Ductility.
- Malleability.
Why is inlay wax colored?
The colors of inlay waxes should contrast with the hues of teeth and dies. Dental waxes are supplied in a variety of colors including blue, green, yellow, red, and ivory. The colors are useful to provide a suitable contrast against a die that is an accurate replica of a prepared tooth or dental arch form.
What is investment material?
Composition • An investment is a mixture of three distinct types of materials: refractory material, binder material, and other chemicals. 15. • Refractory material — It is usually a form of silicon dioxide, such as quartz, tridymite, or cristobalite, or a mixture of these.
What is inlay wax used for?

What is properties of paraffin wax?
Properties. Paraffin wax is mostly found as a white, odorless, tasteless, waxy solid, with a typical melting point between about 46 and 68 °C (115 and 154 °F), and a density of around 900 kg/m3. It is insoluble in water, but soluble in ether, benzene, and certain esters.
What is a dental inlay wax?
Inlay wax—A specialized dental wax that can be applied to dies to form direct or indirect patterns for the lost-wax technique, which is used for the casting of metals or hot pressing of ceramics. Refractory—Capable of sustaining exposure to a high temperature without significant degradation.
