Borosilicate glass is made up of boron trioxide and silica. The glass is noted for its heat resistance and longevity.
It is well-known glassware that has piqued people’s interest, which is why they keep asking the question, “does borosilicate glass contain lead?”
Unlike many other forms of glass, borosilicate glass does not break when exposed to significant temperature changes, making it ideal for a variety of applications ranging from cookware to laboratory use.
Some glassware manufacturers shifted from borosilicate to soda-lime glass because borosilicate glass is far more expensive to produce than other types of glass.
Another reason some manufacturers shifted from borosilicate to soda-lime is that it takes far higher temperatures to create than ordinary glass. It is more difficult and expensive to create since it needs high temperatures.
Let’s find out if borosilicate glass contains lead now that you know what type of glass it is.
DOES BOROSILICATE GLASS CONTAIN LEAD?
Does borosilicate glass contain lead? No, borosilicate glass contains no lead because it is made of non-toxic materials that will not leach harmful chemicals into your food or drink. This glass is also free of BPA, making it ideal for drinking.
Because the substance does not leach out as it does in plastic containers, bottles, and packaging containing BPA, food, and drinks from borosilicate containers frequently taste better.
However, borosilicate glassware products having logo marks on the bottom or body should be tested to ensure that they are lead-free. You can achieve this by testing for lead consent with a Lead Test Swab, which is commonly used in logo design.
BOROSILICATE GLASS PROPERTIES
What properties are used to manufacture borosilicate glass? Borosilicate has the following properties:
- Because it has a lower coefficient of thermal expansion than other types of glass, it is more resistant to temperature changes.
- Borosilicate glass has a high material strength. It resists blunt force impact better than other types of glass. It is heat resistant up to 300°C.
- Borosilicate has a shear modulus of 26.5-27 GPA at 20 degrees Celsius and a Knoop hardness of 400-480.
- It is resistant to corrosion and breaking when exposed to an acidic environment.
- Borosilicate glass is made up of 4% sodium oxide, 3% aluminum oxide, 13% boric oxide, and 80% silica.
BOROSILICATE GLASS TOXIC
Because it resists chemical and acid deterioration, borosilicate glass is absolutely non-toxic and extremely safe to eat or drink from. When using borosilicate glass, you don’t have to worry about dangerous chemicals leaching into your meals and drinks.
Food and beverages really taste better when stored in borosilicate containers since the material does not contain or leach toxic substances like lead and BPA. You can purchase nontoxic borosilicate glass from the list below.

DOES BOROSILICATE GLASS BREAK EASILY?
Because it is thermal shock resistant, sturdy, and does not split when exposed to extreme temperature changes, borosilicate glass does not break easily.
Despite being more resistant to thermal shock than other glasses, borosilicate glass can break or crack when subjected to sudden temperature fluctuations or if not handled carefully.
HOW TO TELL IF DRINKING GLASS CONTAINS LEAD?
Lead poisoning occurs when lead accumulates in the body over a period of months or years. Lead has been related to blood abnormalities and can have a harmful effect on the human nervous system.
So, if you’re concerned about your health, make sure your drinking glass, cookware, or bakeware is lead-free before buying it.
This is how to tell if drinking glass contains lead:
- Gently tap the glass with a metal object and listen to the sound it makes. The drinking glass contains lead if it generates a lengthy or drawn-out ringing sound. Glass, on the other hand, makes a dull “clink” sound.
- Examine the drinking glass’s decorative cuts to see if they are rounded or sharp. It’s a lead crystal glass if the edges are rounded. Sharp ornamental cuts can be seen in the lead-free glass.
- Determine the glass’s weight. Glass made of lead is heavier than glass made of other materials.
DOES GLASS FROM CHINA CONTAIN LEAD?
After conducting a study on this topic, I discovered that China drinking cups with printed comic books, movie characters, or animation contain lead, as well as other dangerous and harmful chemicals that can harm children.
Cadmium, another dangerous element that can harm our health, is also present in decorative glasses. Lead levels in China’s glass enameled logs have been discovered to be as high as 30%.
The truth is that dangerous components in paints and glazes used to adorn glassware have an impact not only on human health but also on the environment.
Which kind of drinking glasses is free of lead? You could be perplexed. Clear, simple glasses with no painted features are the ideal sort of glass to buy for you and your family because they are lead-free. As a result, you can get clear, basic glasses in China.
