Even though we look at the glass as one of the most common building material for various kitchen utensils, windows, wide variety of ornamental small objects, and important part of modern computer communications, its initial use by our earliest ancestors made it one of the most sought after and valuable objects in the entire world.
Bending and drawing glass tubing is a handy skill for managing laboratory glassware. Here is how to do it. Note About Glass There are two main types of glass using in a lab: flint glass and borosilicate glass. Borosilicate glass may carry a label (e.g., Pyrex). Flint glass typically is not labeled. You can bend and draw flint glass
Borosilicate glass is a specialized form of glass that uses boric acid as a component in its fabrication. The result of the addition of the element boron is a type of glass that is very resistant to thermal shock and exhibits a much lower coefficient of thermal expansion than that of common silicate glass. In this article, a review of borosilicate glass will be presented,
Chemistry Lab This is a collection of lab equipment and scientific instruments. Glassware Is Important for a Lab Analytical Balance This type of analytical balance is called a Mettler balance. This is a digital balance used for measuring mass with 0.1 mg precision. Beakers in the Chemistry Lab Centrifuge A centrifuge is a motorized piece
Glass is an amorphous form of matter. It is a solid. You may have heard different explanations about whether glass should be classified as a solid or as a liquid. Here is a look at the modern answer to this question and the explanation behind it. Key Takeaways: Is Glass a Liquid or a Solid? Glass
When you hear the term “glass” you may think of window glass or a drinking glass. However, there are many other types of glass. Glass is the name given to any amorphous (non-crystalline) solid that displays a glass transition near its melting point. This is related to the glass transition temperature, which is the temperature where an amorphous solid becomes
Quartz is an old German word that originally meant something like hard or tough. It is the most common mineral in the continental crust, and the one with the simplest chemical formula: silicon dioxide or SiO2. Quartz is so common in crustal rocks that it’s more notable when quartz is missing than when it’s present. How to
What would a chemistry lab be without glassware? Common types of glassware include beakers, flasks, pipettes, and test tubes. Each of these containers has its own unique form and purpose. Beakers Beakers are the workhorse glassware of any chemistry lab. They come in a variety of sizes and are used for measuring volumes of liquid. Beakers aren’t particularly
Quartz – chemical name silicon dioxide – is one of the most common minerals found on the earth’s surface. Quartz covers a wide variety of stones, many of which are used decoratively for their durability and ornamental nature. Different types of quartz include amethyst (purple quartz), citrine (yellow), rose quartz (light pink), and smoky quartz (dark, translucent
If you’re working in a lab or taking a lab class, you’ll encounter many different kinds of glassware, each of which has features that make it especially well-suited to certain applications. Lab glassware you’re almost guaranteed to encounter includes flasks, beakers, pipets and graduated cylinders. Most serve as tools to measure out quantities of liquids;
