püf noktası

Compound of püf (“onomatopoeic for; a puff of air”) +‎ nokta (“point, spot”) +‎ -(s)ı (possessive suffix with "s" as buffer consonant), literally “puff point”, from a folk tale about either a pottery or glassblowing craftsman and his impatient apprentice wanting to open his own shop, and the master not giving him his leave because the apprentice hadn't yet learned the "puff point" of the art, supposedly where one gently blows on the tiny air bubbles formed in the material to pop them before it's dry to prevent the item from cracking or breaking easily.[1]
