I was building a felt lined wooden box for a chop cup. I had glued the felt into the box using “TIGHTBOND II PRE,IUM WOOD GLUE”. After the glue had dried, I placed my brass chop cup into the box and the next day the cup was heavily tarnished and the side of the cup touching the felt was a lovely turquose tarnish. After cleaning up the cup and waiting a couple days for the box to air out, storing the cup still seemed to tarnish the cup far quicker than just leaving the cup out of the box. After a couple of days the cup had a nice brown/brass patina.
Yesterday I was working on a second felt lined box and right after gluing in the felt, I suspended a bullet wand with brass ferrels that I had previously antiqued with white vingar and roch salt. This morning the wand had an awesome turquose and dark brown patina. So there appears to be a way to accellerate putting a patina on brass by expossing it to the outgassing of the glue and if you add your item within the first 12 hours or so you can add a nice blue/green patina. Just curious, does anyone know how long it takes for a wood glue too completely cure? Any other cool recipes for antiquing brass?

Another way to get a good patina on brass is ammonia. Just place the brass item in a sealed container with an open cup of ammonia. Seems like it takes overnight but might want to experiment with shorter times. Of course follow safety instructions on the bottle.

Titebond II appears to have the highest level of formaldehyde according to an interesting article on the subject of off gassing using a Formaldehyde Release Attenuation Test (see link below).
The original Titebond has the least and Titebond 3 next. The test was done at 7 days so its not surprising that after a day you had a reaction occur after just one day. https://impressionsofaholobiont.com/2018......ldehyde/ |

I'm glad others found it interesting too. I use Titebond3 pretty much exclusively. It has a lower working temp of 45 vs 55 for T2 and 50 for T1.
Also T2, in my experience has some glue adhesion issues with certain woods. |
