Only optical Calcite. It has a different chemical structure than most common Calcite.

A mineral that can form clear crystals that cause double images is what?
Calcite crystal
Is calcite a metal?
No. Calcite is a carbonate mineral.
What rocks have calcite in them?
Limestone and Marble have calcite in them.
Is calcite nonmetallic and white?
calcite is usually transparent
What mineral group does calcite belong?
Calcite belongs to the carbonates.
What are special properties of calcite?
Calcite bends light in a certain way: Double refraction (Double image)
What mineral exhibits double refraction?
Double refraction is when you can see through a mineral and it shows two images instead of one. Calite is the mineral that exhibits it. I linked a great website for this kind of stuff below.
What strategy would allow you to determine clear calcite is not the same as quartz?
A small drop of hydrochloric acid or vinegar would fizz on calcite, not on quartz.Also, quartz has a Mohs hardness of 7 whereas calcite has a hardness of 3. Quartz doesn't have cleavage but calcite has rhombohedral cleavage (skewed square). If the piece of mineral breaks along perfect lines, then it's most likely calcite not quartz. One more thing, if you put the clear calcite on print, like that in a book, you will see a double image through the crystal, an example of double refraction.
Which mineral has double refractivity?
CALCITE
What are five properties for calcite?
pure calcite has good cleavage, is asomewhat soft mineral, has a milky white color, it breaks light up into slow and fast beams giving the illusion of double image of whatever you are looking at on the other side, and the easiest way to tell if your dealing with calcite is to put some HCl acid on it and it will bubble noticeably
Double refraction is a property of some crystals of?
calcite
What is birefringence?
Everyone who is interested in faceting is likely to have seen the double image that is visible through a crystal of calcite. Most know that this is due to a property called 'birefringence' and that highly birefringent materials are often prone to cleavage and hard to polish.

When was Double Image - novel - created?
Double Image - novel - was created in 1998.
What are 2 unusual properties of calcite?
The two unusual properties of calcite are: 1. Calcite fluoresces (floor-esses), that is, it glows, when ultraviolet light is shone upon it. 2. Calcite is birefringent (bye-ree-fringe-unt), which means that it bends light that hits it not once, but twice. So if you were to look through a flat, clear sheet of calcite, you would see everything double.
Which special property is shown if a piece of calcite comes in contact with hydrochloric acid?
double reflection
Why does calcite show twinkling effect?
Calcite has a uniaxial indicatrix with a ellipsoid shape. The two permitted vibration directions (transmitting the ordinary and extraordinary rays), cause twinkling to be observed on rotation.
