To answer this question, you need to understand how heat conduction and combustion work. Here is a possible answer:
When Bunsen gauze gets hot, you see different effects depending on where you light the gas. If you light the gas below the gauze, the flame will only appear at the bottom, but not above the gauze. This is because the gauze is a good conductor of heat, and it takes away the thermal energy that would otherwise ignite the gas above the gauze. If you light the gas above the gauze, the opposite happens. The flame will only appear at the top, but not below the gauze. This is because the gauze also prevents the hot gas from mixing with the cold gas below, which is necessary for combustion.
In some cases, you might be able to lift the flame up with the gauze, if you do it very slowly. This is because the gauze becomes hot enough to ignite the gas above it, and the flame follows the heat source. However, this is not a reliable or safe method, and it should only be done as a demonstration by a teacher.
The blue flame is obtained when the collar is rotated to open the hole fully. This adds lots of oxygen to the burn mix and ensures complete oxidisation (ie blue flame).
typically undergoes heating and may undergo a phase change or chemical reaction depending on its properties. The Bunsen burner provides a consistent and controlled source of heat to increase the temperature of the substance, allowing for various processes such as evaporation, combustion, or decomposition to occur.
Sodium carbonate does decompose when heated, it undergoes thermal decomposition to form sodium oxide (Na2O), carbon dioxide (CO2), and water (H2O). However, the decomposition of sodium carbonate is not easily noticeable when using a Bunsen burner as the high temperature and rapid combustion of the gas can mask the decomposition reaction.
To get a roaring (blue) flame you simply turn the sleeve on the Bunsen burner's chimney to completely open the air hole under it. The new blue flame will be hard to see so close the air hole afterwards to make a visible flame.
Absolutely! Corningware from the day it was sold in 1957, was made for the stovetop, the oven, the microwave, the dishwasher, refrigerator and the freezer. The material that Corningware was made from, called Pyroceram was a glass-ceramic material that could withstand quick changes between hot and cold without breakage or problems. Corning made millions of the white dishes in a variety of schemes over a thirty year period. Look on the bottom of your dishes, and you will see the markings for its usage. The dishes with handles are the best ones for stovetop usage, and earlier editions had a removable handle for stovetop use. Dishes such as souffle dishes, pie plates, etc. while they can be used on the stovetop are not practical since they lack handles. Corning also in the 1980's made a line of Visions cookware in amber and cranberry colors, that was also a glass-ceramic material for stovetop, oven, microwave, dishwasher, refrigerator and freezer usage.
About the year 2000, Corning the company sold its housewares Consumer division, and thus no longer make the "Vintage Corningware" or Visions cookware. A new company, World Kitchens now markets the brand Corningware, but they use a material called stoneware to make the dishes. These dishes are not made for stovetop usage, they are to be used in the oven, the microwave, the dishwasher, and refrigerator, and maybe the freezer - but not for quick changes in the temperature. Again, these items made from stoneware CAN NOT be used on the stove top.There are markings on the product and box that make this very clear. World Kitchens, which now markets all the kitchenware products that used to be made by Corning does not make any products for the stovetop.
There are several places online to obtain Vintage Corningware and Visions cookware.
Parlez vous Pyroflam? When World Kitchen observed the 50th anniversary of the CorningWare name in 2008, they added a StoveTop collection to their online store, including a set of casseroles in the traditional Blue Cornflower pattern. The StoveTop line is called Pyroceram in the USA but it's made in France by ARC International. It's sold in the rest of the world as Pyroflam and was originally called Arcoflam.
Cooking foil is made from tin. Sometimes it is made from very thin sheets of aluminum. This is because it is cheaper.
Disk burners can be purchased anywhere that sells computer equipment. Popular choices would be Best Buy, Office Max, and Office Depot. Of course there's always online choices like Amazon and eBay.
Because that is just cold unburnt gas

Yes, these are pretty decent clubs. They are Taylormade's game improvement range, so are ideal for beginners and mid handicappers.
The yellow flame is more visible - making it easier for others to see. It's also a colder flame than the blue conical one.
The purpose of the 3cm is to avoid danger and our safety.
