Trivia about Japanese wax

"Haze tree"
Rhus succedanea or "Haze tree" is deciduous belongs to Anacardiaceae. In the end of 16th century, a Japanese named Sojin Kamiya (1551~1635) imported the tree from the southern part of China and planted in Karatsu area in Northern Kyushu. Later, it expanded to Chikuzen area (now Fukuoka prefecture). Since the beginning of Edo era, production and demand of tree wax had increased. As the wood wax has a sticky minute organization, it won’t make cracks or specks when candle is made.

It is said the reason candles made of wood wax are fat on the upper part is to obtain a large flame and light for awhile after ignition.

"Usage of wood wax"
Wood wax is mainly used for candle, but exposed wax is used for ointment, polishing substance and cosmetics such as pomade.

"Exposed wax (called "white wax" also)"
