Botched refinished teak chairs? - Black streaks and discoloration  

It would be good to know why sending was preferred over simply using steel wool. Black is present in teak, I would not mind it.

Don't worry. Be happi.

The sanding exposed wood that has not been exposed to UV light from the sun. The dark stripes absorb higher energy light and so they are bleached out much, much faster than the oranges and yellows. I rather prefer the dark stripes, but if you really want them to disappear put the chair out in the sunlight for a few days. Note that glass blocks almost all the UV light so you really want direct sunlight.

It's just as teak should be, I wouldn't worry. Next time, ask your restorer to avoid heavy sanding, it's very rarely necessary.

Additionally, despite the limited scope of the photographs I feel like this thread might be interesting to you:

Those chairs look like they were expertly refinished. That teak is exactly as it should be. If you like bland looking teak, you need to find some chairs made in the late 1970s. The beauty of the color variation in teak, walnut, and rosewood, is exactly why the Danish designers used these materials. Everything Leif says above is spot on. You chairs were designed by Henning Kjaernulf. I have not seen Aunt Mark in some time, has anyone checked on him?

Dark grain patterns are great! I have a Tove & Edvard Kindt-Larsen table that has some wild ones, adds so much character.

It is not mandatory reading but highly recommended.

Beautiful chairs! That grain may grow on you. Give it time. I find the things I love most and for the longest are often things I didn't care for much at first.

Aunt Mark was traveling for the summer but he should be back soon, i would think. I hope so!

That nakashima book will be my next reading, thank you minimoma

Thanks Spanky, good to hear our Aunti Mark is doing well. He pulled his plane out of the hanger, and took it for spin, no doubt. Hope his travels are going well!!!

Thank you all for the feedback. The black, darker areas I can live with given it

One more that captures it a bit better. It

I should point out that the light yellow discoloration starts at the point in which the piece curves and has been shaped/rounded which then leads to the top part. The top part is mostly dark orange with a few bands of yellow. Not sure if it was sanded in this area too much or not enough. Just know that it

That back strut is made from bent plywood. Basically bent layers of wood, so there is a discrepancy in colour between the layers, there is no way to change and it will have always been the case.
