What happens when wax starts to smoke?
When iron is too hot, you can partly burn wax. Overheated wax molecules pass to a liquid state and then to gas. Atom ties inside the molecule start to break and form bonds with the air oxygen. This reaction creates two different chemical products, water (vapour) and carbon dioxide (gas). This a one-way process, new substances cannot be transformed back to wax. CH-waxes without additives This explication is only valid for CH waxes in blocks without additives. LF and HF waxes As for LF and HF waxes that include PTFE polymers (called fluorine), when you exceed the PTFE melting point, that is 320C, this polymer starts to decompose and finally transforms into vapour and forms bonds with oxygen. This leads to the creation of a highly toxic gaseous product. The maximum temperature of the iron is 180C, so you shouldnt worry. The only way to overheat these waxes is to expose them to high temperatures of flames, heat guns or cigarette smoke Cera Once you grasped the first part of our article whe
