The flame spread rating of carpet is typically measured on a scale of 0 to 200, with lower numbers indicating a slower rate of flame spread. Carpet with a lower flame spread rating is considered safer in the event of a fire.
A flame spread rating is calculated by measuring the rate at which flames spread along the surface of a material under controlled conditions. The rating is determined by comparing the material's performance to that of red oak, which is given a flame spread rating of 100. Materials with lower ratings have slower flame spread rates, indicating better fire resistance.
Flame spread 10 is a rating associated with the surface burning characteristics of a material. It means that the material has a low flame spread index and is considered to have good fire-resistant properties. Materials with a flame spread 10 rating are slow to ignite and will not contribute significantly to the spread of fire.
A surface flame spread rating of not more than 150 indicates that the material has a relatively low propensity for flame spread. This rating is determined through standardized testing procedures and indicates that the material is considered to have moderate fire resistance properties. It is important for materials used in buildings to have low flame spread ratings to reduce the potential for fire hazards.
Flame Spread 20 is a fire resistance rating given to materials that exhibit moderate flame spread. This means they have a moderate capacity to resist the spread of fire. A lower number indicates better fire resistance, while higher numbers indicate more rapid flame spread.

The test method used to assess the effectiveness of flame retardant products is BS476, Part 7 1987 and is used to classify a material in terms of "Spread of Flame". Class 1 is a low surface spread of flame, the highest achievable with the test method and is a performance normally required for walls and ceilings. In high risk areas such as escape routes Class 0, limited combustibility, is required. To comply materials must have a Class 1 Surface Spread of Flame and a low fire propagation to BS 476 Part 6 1989. Intumescent coatings are used to prevent the penetration of fire through a structure for a specific period in accordance with BS 476 pARTS 20-23 1987. Such coatings are given classifications with specific periods of time achievements, such as "30 minutes".
Heating a flask on a flame with a wire gauze helps distribute the heat evenly and prevents direct contact between the flame and the glass, minimizing the risk of the glass breaking. The wire gauze also helps to spread the heat more uniformly, reducing the chances of hot spots developing in the glass.
well not usually when you keep trying your best to make the flame from glass fire pits burn in colors of the glass

The flame color of sodium through a cobalt glass appears yellow, while the flame color of potassium through a cobalt glass appears lilac or pale violet. The cobalt glass filters out certain colors, allowing specific wavelengths to pass through, which affects the observed flame color.
