The bead of borax with some powdered sample is heated in a flame; the color of the bead is specific for each element and is used as a qualitative analysis.
On heating, borax first loses water molecules and swells up.On further heating it turns into a transparent liquid, which solidifies into glass like material known as borax bead. Na2B4O7.10H2O -----heat------>Na2B4O7------heat------>2NaBO2+B2O3 Sodium Boric metaborate anhydride
Bang Bead was created in 2000.
The rationale of the bead in the WBC pipette is for recognition. Through the white bead present inside the pipette it would be easy for a medical technologist to determine the pipette that should be used for differential counting. Aside from identification purposes, white bead is also used as a signal during the shaking procedure that would indicate that the components inside the pipet are mixed.
A continuous and uniform line of filler metal is called a "weld bead." This bead is formed during welding when filler material is melted and deposited in a controlled manner to join two or more workpieces. The quality and uniformity of the weld bead are critical for the strength and integrity of the welded joint.
The borax bead test is a qualitative analytical test used to identify certain metallic ions based on the color of the borax bead after heating with the sample. The test involves melting a small amount of borax with the sample on a platinum wire loop and observing the color of the resulting borax bead under a flame. Different metal ions produce distinct colored beads, aiding in their identification.

Alkali metals such as sodium, potassium, and lithium typically do not respond to the borax bead test. This is because their complexes with boron are colorless and difficult to detect.

Platinum is used in the borax bead test because it is chemically inert and does not react with the substances being tested. This allows for accurate observation of color changes that indicate the presence of certain metal ions. Additionally, platinum is malleable and can easily be shaped into a small loop for the test.
When heated borax undergoes various transitions,first it loses water molecules and swells,then it turns into a transparent liquid solidifying to for a glass like structure called borax beads. Na2B4O7.10H20 -->heating Na2B4O7 -->heating 2NaBO2 + B2O3 BORAX SODIUM BORIC METABORATE ANHYDRIDE
