This is chestnut*, at least 400 years old:
This is the finish I applied:
Note it's a clear coat (incoloro= uncoloured). This is what happened:
That looks an awful lot like a tannin reaction to me. Is that possible in 400 year old wood which has spent its entire life outside?
I don't know what the product is that I was using. It was spirit based, and looked just like a varnish to me, but the guy in the shop said it wasn't a varnish. Does anyone know what it is? Although I was deeply disappointed with the colour change, I've come around a bit towards liking it as it helps with the contrast to the bricks. The person that counts, my customer (my daughter), loves it, so I shouldn't be so disappointed I guess.
* The top shelf is (probably) elm, and you can see that it didn't react so much.
