    I used to do large smelts outside. I had about a 1,000 pounds melted when a sudden cloud burst came thru with very heavy rain. Lots of steam and sizzle but no tinsel fairly even with large heavy hard rain drops. The water has to get under the surface before it becomes an issue.

    Oh, who hasn't done that! Only wusses wet their digits first! And they didn't leave their fingers in it for any length of time either!

    Me, that's who. I'd rather watch other people do it. I don't drink beer so you'll never hear, "Here, hold my beer and watch this!", come out of my lips.

    I drink beer, however, I have never uttered these words. I leave that to others and watch.

    My next door neighbor gave me a 5 gallon bucket 2/3s full of fishing weights that he found while metal detecting on the beach. They had been in his garage for at least a year out of the weather. About half way through the bucket I carefully placed a large egg sinker in the pot and about 15 seconds later had an explosion that blew lead all over the shop, on me and my clothes. I can only guess but its an educated one, that in the hole through the center of the egg sinker sand had trapped water in the middle and it got hot enough to turn to steam and made the mess. I will in the future run a drill bit through the center of all the egg sinkers I can not see through.

    When I suspect internal moisture, I put them in a cold pot and let them heat up with it.
    That way, the water will boil out way before the Lead melts, and not make a sudden steam explosion.

    Pre-heat everything, including ingots you are about to add to a molten pot of alloy. Double this if you're in a high humidity part of the world. Cast in an area you have a bit of room to run if need be. That's all I have to say about that.

    I have had visits from the tinsel fairy twice. The first was when I was unaware of the issue and dropped a couple of bullets back in the pot that had just been pulled from the water drop. The second time I was putting reject boolets back in the pot that had been cast several days before but some had voids in the bottom and one apparently had a bit of water in a void. Now all lead going in melted lead gets pre heated.
    I think putting used fishing weights, especially deep water weights in hot lead without preheating very well, could get ugly. The high pressure from being deep in water will drive water into tiny voids where it wouldn't normally get to.
    The tinsel fairy has emptied 10lb Lee pots on me twice and I don't want it to happen again. Also I am fairly sure you won't have time to run even if you were already standing and had the room. The tinsel fairy is very fast.

    That is the understatement of the year.

    Drops of rain falling into the pot evaporate upon contact with the surface.
    But I once had a blonde moment of misfortune and stuck a slightly moist fork into the pot, to stir. The molten alloy protested wildly and sprayed me with drops. Nothing catastrophic though.

    Starting out, the unheated ingots I added to the melt, stored without environmental control, bubbled ominously but didn’t explode. Blind beginner’s luck. Now the only lead going into the melt that doesn’t first sit on the pot rim are culls, fresh sprues, and molten lead from the feeder pot. Metal tools also get a cautious preheat before taking the plunge.

    Folks often point out that the volume expansion of water from liquid to steam is 1600 fold. That’s the change at 212°. At 700-800°, it’s more like 2000 fold.

    Casting at night under lights on my deck, moths falling into the melt will roast, but no tinsel fairly visits. Maybe they’re not as heavy or dense as grasshoppers.

    Winger Ed i had no idea that after that much time there could be moisture still in the sinkers.

    Oh yeah.
    If it's trapped in there--- like herpes,,,, its for life.

    I've even had some exciting results by dropping cold Lead into the pot on a cool & humid day.

    Propane has a lot of hydrogen which produces water as it burns which saturate the combustion gases. Passing cold lead through those humid gases will condense water on the lead. If that water gets trapped under molten lead you will have a steam explosion.

    I've seen the wet hand in molten lead trick. If the steam has a path to the surface, you might get a free pass but I wouldn't count on it.

    Check out pictures of steam engines that exploded, everything above the wheels gone.

    interesting thing, I had a small burp come out of my caster one day, and realized that I had put a piece of lead in and my hand had been sweaty, never did that again., that can be expected, but here is what I did not expect yesterday. I put a piece of carnuba wax in (size of a pea)and let it melt then started mixing it in to flux the lead a little bit. had a minor eruption and fireball. quite spectacular. not as spectacular as you guys "tinsel fairy" but good enough to ruin a pair of shoes and socks, spash the wall and put quite a bit on the table, unlike a violent eruption from water, this was more of a splash then an explosion. any ideas why?
