Checking the temperature by testing the tool on a piece of white paper towel is performed for:

• A. Stove-heated thermal irons and combs
• B. Electric irons
• C. Gas irons
• D. All types of irons

Answer: (A)

Humans need to know a tool’s actual heat before applying it to hair to avoid scorching or damaging strands. When using stove-heated thermal irons and combs, there isn’t a built-in temperature readout or precise control like you’d have with electric or gas-powered tools. A quick test on a piece of white paper towel shows how hot the tool surface really is: if the towel browns, scorches, or smokes, the iron is too hot and needs to be cooled or adjusted before contact with hair. This simple check helps ensure the tool is at a safe level for styling.

Electric irons and gas irons typically have more reliable temperature controls or settings, so they rely on those controls rather than a tissue test to judge heat.
