It depends what its made from. Natural opals made from silica have a high melting point around ~1600 celsius. These are common structures in research as silica spheres are easy to make with the stober method and form opals using the colvin method. The other 2 common types of opals created synthetically are PMMA, polystyrene. Polystyrene melts areound 120 celsius, PMMA melts at 160 celsius.

What is difference between melting point and drop melting point?
The melting point is the temperature at which a solid substance transitions to a liquid state. The drop melting point is a method of determining the melting point where a small amount of the substance is heated until it melts and then allowed to drop onto a solid surface to observe the melting point. Drop melting point is often used when the substance being tested has a high melting point or when observing the melting process is critical.
The temperature at which a solid melts is called?
The temperature at which a solid melts is called the melting point. At this temperature, the solid transitions into a liquid state.
Is the melting point of bromine higher or lower than the melting point of chlorine?
The melting point of bromine is -7,2 0C. The melting point of chlorine is -101,5 0C.
What becomes solid above the melting point?
A substance becomes solid above its melting point. At temperatures below the melting point, the substance typically exists in a liquid state.
What is melting point of ramipril?
The melting point is 109 oC.
