The purpose of these plants was to show off my green thumb. As part of my experimentation with water propagation, I thought these containers would make some lovely It's a pleasure to inform you everything looks good! Based on the reviews, I honestly thought they would be a bit smaller than I'm finding them to be! I am very pleased with the condition of everything. Not a single piece was broken.
The number of times I used this is probably less than a dozen. The only use of heat is for mixing oils and tinctures. It just shattered all the way from the top to the bottom after a regular wash in the sink, with nothing falling on it. The borosilicate glass I use is much more durable, so I would expect more resilience from it.
I have one 12-inch The year is A boy in his class wanted a science-themed party so we designed a cake for him and made the cake topper out of a flask. We had a great time at the party with these flasks. A jellied one was inside the other They were made out of cupcakes and decorated with candy. The other two (not pictured) were used as cake toppers. A sturdy flask with the right size was just what we needed.
It goes without saying that as a family who homeschools This was purchased for my daughter's science birthday party where we were making a decorative project with colored water and dry ice. The quality of these is great. In a homeschooling family, I am sure we will find even more uses for them.
The people at work always smile when they see them lined up with plant cuttings - I have them on my desk at work. If you watch the cuttings closely, you can see how quickly they root. It is important to the plants that they don't fall into the water thanks to the small opening. Your desk will look great with them together. By having a small opening at the top, oxygen can be kept in the water and evaporation is prevented. A lack of natural light makes them ideal for use in an office.
This is great for making smaller batches of products because of their size. They are of great quality and are very affordable. As is the case with many erlenmyer flasks, these aren't marked 100% accurately so if you're going to use them for measuring, calibrate them with a graduated cylinder and water first so you get an accurate proportion.
The glasses shipped quickly and were packaged beautifully in individual boxes. It can be risky ordering glassware online, but these were well packaged and shipped quickly. The pieces arrived undamaged, the markings were clear, and the price fit the quality of the set. The addition of this lab is great for our homeschool students.
The rims of these have bubbles in the glass, but they are functional. My doubts are that heating them will work, as I haven't tried it yet. Apart from that, they are perfect. It would be nice if there was a little more craftsmanship involved with.
