Ebonizing with tea and iron
Blacksmiths and woodworkers in the 19th century were already darkening wood with vinegar that had rusty nails soaking in it — it was the old way of imitating fine dark woods. The acid in vinegar dissolves the iron and creates a solution that reacts with the wood's tannins, giving the pallet an aged, deep tone without any paint.
What you need
- Steel wool or a rusty nail
- White vinegar (enough to cover)
- A glass jar with a loosely fitting lid
- 2 to 3 black tea bags
- Brush or cloth
- Fine sandpaper (220 grit)
How to make it
-
1
Place the steel wool in the jar and cover with vinegar; cap it without sealing airtight, because the reaction releases gas and the jar could burst with a tight lid.
-
2
Let it rest for 24 to 48 hours, until the liquid turns dark — that's when the acid has dissolved the iron and the solution is active.
-
3
Meanwhile, sand the pallet wood and apply 2 to 3 coats of warm black tea with a brush; the tea deposits tannins, the "food" the iron solution needs to react.
-
4
Brush on the iron solution and watch: within minutes the wood darkens on its own, because the iron reacts with the tannins and oxidizes inside the fiber.
-
5
Repeat the application until you reach the desired tone — more coats, darker and more even.
-
6
Let it dry thoroughly for a few hours before handling, or sand lightly to smooth the raised fibers.
Finishing touches
Pallet woods vary in tone, so always test on a hidden little spot first. To protect the piece, finish with wax or cooking oil applied very thinly with a cloth.
