A Blue Glass is a glass of water with blue food coloring in it. It’s used to help you determine if your tap water has fluoride or not, and how much fluoride there is in the water. You can also use this test for other chemicals that are added to our drinking waters such as chlorine, chloramine (chlorine + ammonia), arsenic, lead and copper.

Blue Glass: Frequently asked questions

What types of Blue Glass are there and what determines a good product?

There are two types of Blue Glass. The first is the common blue glass that we see in our everyday lives and the second type is a rarer, more expensive form called cobalt blue glass. Cobalt blue glass has been used since ancient times to make jewelry and other decorative items because it was believed to have magical powers such as warding off evil spirits or bringing good luck. It also had healing properties for some people who thought they could cure their ailments by wearing this special kind of jewelry made with cobalt blue colored beads or stones (such as turquoise). Today, you can still find many examples of antique pieces from around the world that were created using this beautiful material.

The most important thing is the color. It should be a nice, deep blue with no yellow or green tints to it. A good Blue Glass will also have an even texture and not too many bubbles in it (bubbles are bad). If you can see through the glass when held up to light, that’s another sign of quality – but this isn’t always possible because some types of Blue Glass contain metal oxides which make them opaque (this is true for all colors except clear/transparent glasses).

Who should use a Blue Glass?

Anyone who is looking to reduce the amount of blue light they are exposed to during the day. This includes people with computer vision syndrome, eye strain or fatigue and those that want a more natural sleep cycle at night.

Based on what criteria should you buy a Blue Glass?

A Blue Glass is a great addition to any home, but it should be purchased based on the following criteria. First and foremost, you need to determine if your kitchen has enough space for a large piece of glassware. If not, then consider purchasing smaller pieces or go with something else entirely (like our Red Wine glasses). You also want to make sure that the color will complement your existing decor as well as fit in with future purchases. Finally, think about how often you plan on using this item because there are some people who only use their blue wine glasses once per year during St. Patrick’s Day.

The most important thing to look out for when comparing a Blue Glass is the quality of glass. Look at where it was made and what materials were used in its construction, as well as whether or not it has been treated with any chemicals that may have an effect on your health. If you are looking for something specific like a blue wine glass then make sure you check if they offer such items before making your purchase decision so that there will be no surprises later on down the line.

What are the advantages and disadvantages of a Blue Glass?

Advantages

Blue Glass is a very good insulator. It has the same thermal properties as glass, but it also blocks UV rays and infrared radiation (heat). This means that you can use less energy to keep your home warm in winter or cool in summer.

Disadvantages

The main disadvantage of a blue glass is that it can be hard to see through. If you are looking for an easy-to-see filter, then this may not be the right choice for you. It also tends to darken your view and make everything look like it’s taking place at dusk or dawn. This makes them great if you want to take pictures in low light conditions but less than ideal when trying to get good shots during the day time hours. Another thing about these filters is that they tend to distort colors more than other types of filters do so some people find their photos don’t turn out as well with one on as without one on because of how much color changes there are in comparison with what was originally seen by eye before being photographed.
