The engraving is also engraved into a cup, which is then held up to the light, to show the engravings on the outside of the cup.
The engravings are meant to be seen through the light.
The glasses are made from a ceramic material, called enamel.
They are made of plastic, and are also engraved.
The light inside the glasses is created by reflecting the light of the candles.
It is called the diffused light.
There are also special lenses in the glasses that allow the light to be diffused through a material called enamels, which creates a reflection of the light in the glass, said David LeBlanc, associate professor of optics and materials science at the University of Waterloo.
“It’s not just a piece of glass, it’s a prism,” he said.
“When the light hits the enamel, it diffuses through the enamel and creates a different reflection, which in turn diffuses the light again, creating a very different reflection.”
The light is also diffused into the glass itself, so that the diffusing effect is stronger, he said, and the reflection is more clear.
“The reflection of light through enameled glass is very much the same as the reflection of a mirror through a prism.
It’s just different in that you can see it, but you don’t see it through the glass,” LeBlac said.
He said the diffuser glass in the light-sensitive lenses is one of the reasons it’s called diffused glass.
“Because you’re not only seeing the reflection but also the light itself.
So it creates a very diffused effect,” he added.
There is a special lens in the diffusers, called a diffraction lens, to focus the light onto a particular surface.
“It allows you to see more detail in the reflections,” Leblanc said.
“In general, the reflection that we’re looking for is the reflection from the glass into the light,” he explained.
“So we can see through the reflection.
But the reflection does not affect the light.”
There is no clear evidence that this method of reflecting light is superior to other light-reflecting glasses, he added, but the diffusion of light from the glasses does create an effect that is similar to the diffraction of light that is achieved by mirror reflection.
“You can’t really say that these are superior because you can’t tell that they’re the same thing, but they’re very similar,” Le Blanc said of the diffractive glass.
The two lenses are designed to create the diffusor effect.
It occurs when a light wave is reflected off a mirror onto a surface.
That surface is then reflected off the mirror again, in a process known as refraction, and then again onto the mirror, in an identical way, creating an image.
LeBlace said the mirror reflection effect is what allows the glasses to be light-emitting.
It takes a lot of light to produce the diffusion effect.
“If you have a mirror, it doesn’t have a diffuser, so the diffuse effect is the same,” Le Blanc said.
But in an enamel-enameled light-resistant glass, the diffusive effect is not the same.
Le Blanc explained that the mirror reflects light off the enamelled surface, which absorbs it, and that then diffuses it through a surface, creating diffusors.
That creates a refraction effect, which gives a light that reflects off the glass a different effect than the reflection off the surface.
“You’re not seeing the refraction of the reflection, but what’s reflected from the surface,” he told CBC News.
“If you look at a reflection, you can actually see that the reflection looks different than the refracted reflection that you see on a surface.”
He said in order to make the reflection appear more clear, the refracting surface must be light sensitive.
“But if the surface is not light sensitive, you won’t see the reflection clearly,” he noted.
“The refractive index, which relates to the refractive strength of the surface, determines how well the reflection can be seen,” he continued.
He also said there is some debate about the best way to create a diffusive diffuser.
Some experts have suggested that the lens is placed so that it is reflected from a light source, such as a mirror or a fluorescent light bulb, and this will reduce the diffracting effect of the glass.
“In that case, the light coming out of the bulb will not be reflected off, but it will be reflected onto the glass surface,” Le Blake said.
If the glass is made from enameling materials, such a light bulb will reflect the light off, making the glass appear to be reflecting light, he explained, but that does not happen if the glass used in the lamp is enamel, which reflects light
