My son took a piece of leather to school this morning.
His teacher has a moth problem.
Richard is 10. Yesterday his teacher mentioned moths in her closet.
This morning he grabbed a piece of chestnut-tanned leather from our shelf and said he’ll need it today.
The leather came from Eugenia Presot, who runs Conceria Presot in Porcia – family tannery since 1932. When she gave us the scraps, she said: „Put a piece in your closet. Keeps the moths away. We’ve always done it.“
Richard remembered.
He wanted to tell his class:
The leather was tanned with chestnut extract. The tannin comes from the wood. And no, nobody cuts down forests for it. Chestnut trees are coppiced. You cut them back, and they grow back stronger.
Those tannins are hard for insects to digest. A natural defence against fungi, bacteria, and insects. And when you tan leather with it, those properties stay in the material. No chemicals, just tannins.
Bet you didn’t know that either?
You’re welcome.
