| 词条 | Heatproof mat |
| 释义 | {{Unreferenced|date=December 2009}} A heatproof mat is a piece of apparatus commonly used in tabletop lab experiments that involve moderate temperatures (for example, when a Bunsen burner is being used) to prevent damage to a work surface. They may also be used for domestic equipment, such as hair straighteners, hair dryers or other hot objects. Traditionally, such mats were made of asbestos, often reinforced with a metal mesh, but fiberglass or other substitutes are now used because of the toxicity of asbestos fibres. {{DEFAULTSORT:Heatproof Mat}}{{Chemistry-stub}} 1 : Laboratory equipment |
