Tian Bai told her that two of the wood pieces in the rosewood pile are actually wisteria, also known as siamese rosewood.
Before leaving the house, she had already prepared the tools necessary for verifying the authenticity of precious woods like rosewood.
She took out several glass cups, "Mr. Singer, could you help me by cutting a few shavings from your pile of rosewood?"
"Of course." Following Xiao'er's request, shavings from each piece of wood were carefully prepared.
Xiao'er placed some of the shavings into the glass cups, marked them, added a certain proportion of water, and then left them aside.
She first took these wood shavings and drew on white paper, all of which showed a purple-red streak. "When rosewood is scraped onto paper, it leaves a purple-red streak. Use the same strength, scrape it a few times until the streak fades and disappears before moving on to the next step," Xiao'er explained to Shen Chengyao.
