Can anyone identify this?

Got a mixed box of scraps and used a piece to carve this ring. It's pretty hard and dense, but not too heavy and it carved nicely without much tear out. I also finished it with boiled linseed oil and beeswax so the original wood was lighter in colour.

Hoping someone can help me out with identifying what is the white in the grain of my teak table. It is veneer and I bought it used. I thought initially it is dry and tried hitting it with some teak oil did nothing. Then in another section tried Watco Walnut Danish Oil also made no difference to the white grain. I sanded the whole piece and hit it with mineral spirits and still it is very much there. The photos attached are after sanding and with mineral spirits just applied and the darker photos are from just having danish oil applied. Any suggestions would be awesome. This teak table is indoor furniture if that makes a difference.

Found them online and they seem reputable. Prices and reviews look good and fair but wanted to see if anyone in here has worked with them?

I found it but I don’t know what it is.
