Heating pottery or clay sculpture to a temperature high enough to render it. If it is produced at lower temperatures and pressures and with the use of a catalyst, a much higher density (HDP) polythene is produced. An object made of ceramic materials with a specific melting point ,used to.Polythene for example can be made at high pressure and moderate temperature to produce low density polythene (LDP) which is used for bags and bottles where flexibility is needed.ACerS and its Meetings team will continue to comply with guidance from the Centers for Disease Control, relevant state and local authorities, and each conference venue in an effort to provide a safe and healthy environment for our meeting attendees during the ongoing COVID-19.
