what is sapphire crystal glass

Sapphire glass, is made synthetically and isn’t actually considered a glass but a crystal. Though sapphire crystal resists scratches, it can still break easily if you drop your phone. If a scratch-proof phone that never needs a display cover sounds excellent to you, you might benefit from purchasing a sapphire glass smartphone. The Rohje Sapphire crystal is 8-9 on the Mohs scale, being nearly unscratchable.We have focused on the chosen sapphire crystals details.

Next I’ll explain why.Sapphire glass, is made synthetically and isn’t actually considered a glass but a crystal. Other people might not even notice it, but it might bother you when you are aware of it. It’s thermally stable to Though sapphire glass seems like the perfect material for smartphone covers, it’s not used in all brands for several reasons. We keep a close eye on China because of its influence now The same way acrylic glass, meaning a “glass” made of plastic, can take hits because of its flexibility, but is scratched very easily.We see that being able to be scratched and being able to take impacts are opposite qualities. The term sapphire glass can be quite a misnomer. These are then cut with diamond saws, grinded and polished to the finished “glass” product. That’s why the colour of the face our Adventurister Dark watch models can be seen turning a tiny amount blue when looked from a specific angle.The glass of the Rohje Adventurister watch is coated with this anti-reflective coating. Hardness is measured with the Mohs scale of mineral hardness from 1 to 10.Diamond is the most hard with its value of 10, it can scratch all other minerals. It is in fact a transparent crystal of sapphire. We at Rohje have aimed to make the watch one that won’t get scratched at all. We want our watches to work, but also look good for a long time, so that is why we ended up coating only the inside of the glass.Subscribe our Rohje-letter and be up on date with us. Mineral glass is around 5-6 and acrylic around 3. Unlike its natural counterpart, this type of sapphire is synthetically produced in a lab. Sapphire glass is an artificially created sapphire created in a lab. But after formation, the crystal is not in the thin sheets needed for smartphones and similar applications — it needs to be cut. The synthetic manufacturing process produces a crystal that is only Sapphire glass starts out as aluminum oxide powder. With a hardness of 9 on the Mohs scale it has a considerably higher scratch resistance and a resistance to fracture than mineral glass.With these properties, it is only by exceeded the diamond (Mohs hardness of 10).. Anti-reflective treatment (Image: Though some smartphones use sapphire glass now, it’s only on specific models. The sapphire crystal is made in very high temperatures and it made up from crystalline aluminium oxides. This process is slow and energy-intensive a fact which of course we all know can result in one thing, it’s expensive! With so many new smartphones coming out in a variety of sizes, even reusing the sapphire glass faces from phones would be expensive because they would need re-machining to cut them down to the new size.Sadly, the one aspect that makes sapphire glass desirable, also makes it more fragile. Sometimes even acrylic, meaning plastic.We find sapphire crystal, meaning sapphire glass serves Rohje watches the best. Consider the chic and well-priced Eco-Drive by Citizen. This synthetically produced sapphire is only chemically related to mined gemstones that share its name.

The sapphire is then machined into its final form and polished for many hours to produce the desired finish.
