Final answer:
When tempering a new pressing comb, it's important not to let it cool rapidly, as this could harm the tool and its effectiveness. The correct tempering method includes a light oil coating and wiping with a clean cloth, ensuring gradual cooling.
Step-by-step explanation:
When tempering a new pressing comb, one should not leave it to cool rapidly. Proper tempering typically involves the application of a light oil coating, perhaps some gentle heating, and wiping with a clean cloth. Rapid cooling could cause the metal to become too hard or brittle, potentially leading to damaged hair or tools. This process is akin to tempering chocolate as well; both require controlled conditions to optimize the tool or product's performance. It's important to treat heating tools with care, including avoiding sudden temperature changes which can lead to structural weaknesses.
Warning: While handling any hot tools or implements, such as when tempering a pressing comb in hot water, always exercise caution. Never touch hot equipment directly with your hands as you can easily burn yourself.
