// Definition
A PTFE (polytetrafluoroethylene) non-stick sheet used as an alternative to parchment paper when pressing rosin. Teflon sheets spread heat more evenly across the surface area and have a thermal surface similar to cellophane, allowing lower temperatures with higher pressure.
// From the Episode
Tony Verzura advocates strongly for Teflon over parchment paper, explaining that its thermal surface distributes heat more evenly whereas parchment transfers heat through like cotton. Jeff is described as preferring parchment but slowly coming around to Teflon's advantages for rosin production.
