There are a number of circumstances when a hot plate would be used. Cooking is one of these. Hot plates are also extensively used in chemistry laboratories.
To distinguish between a mineral with a hardness of 6 and one with a hardness of 4, you can use the glass plate and the copper penny for comparison. First, scratch the mineral against the glass plate; if it scratches the glass, it has a hardness greater than 5. Then, use the copper penny to scratch the mineral; if the mineral scratches the penny, it has a hardness greater than 3. If it scratches the glass but not the penny, it has a hardness of 6; if it scratches the penny but not the glass, it has a hardness of 4.
The rectangular glass plate you are referring to is likely a microscope slide. Microscope slides are commonly used in laboratories to hold samples for viewing under a microscope. They provide a flat and transparent surface that allows light to pass through the sample for observation.
A mineral that can scratch glass but not a streak plate is quartz. Quartz has a hardness of 7 on the Mohs scale, which allows it to scratch glass (which has a hardness of about 5.5) but is harder than the streak plate, typically made from porcelain, which has a hardness of around 6-7. Therefore, while quartz can leave scratches on glass, it will not produce a streak on a streak plate.
All glass will melt given sufficient heat. There are certain heat resistant glass wear used for cooking and in laboratories..
== == You put a specimen on a glass plate and then view the specimen under a microscope. It acts sort of like a slide.

The type of glass used in laboratories is BOROSILICATE it is a heat resistant glass. It's main constituents are silica, which is used in normal glass, and boron.
Use clear silicon--it has "give" and is not rigid.
TOO long, that is why you should use paper or re-use a glass plate
The actual thickness of plate glass can vary depending on the manufacturer and intended use. Typically, plate glass can range in thickness from 2mm to 25mm or more. It is important to consult with the supplier or manufacturer to determine the specific thickness required for your project.
Microwaves generally do not come with extra glass plates but you can purchase an extra glass plate.
if we use glass plate then ring's will be clear

If you still have the backing plate available you can use it RTV silicone adhesive to mount the glass to the backing plate. If you have not yet purchased the mirror glass we do have them available for $19.99 shipped and they include adhesive mounting tabs designed specifically for mounting glass to the backing plate.
