Have you heard about the little trick of inserting a long lag bolt into your nitre bath before it cools and solidifies, and then unscrewing it to leave a vent hole to prevent pressure build-up the next time you heat it. A rupture through the still solid crust at 633 degrees F will ruin your day.
Thanks.
Yes, That's exactly what I'm talking about. I'd think it'd work well, pointed at the melted solution, mainly to be able to keep it from getting too hot. I've read if it gets too hot the colors won't come out well.
I've heard of the "bolt trick", folks say it was listed in one of the "Gunsmith Kinks" books. I don't have the books yet, but there seems to be lot's of info in them.
