I found this in a pile of rubble behind an overgrown hedge. It weighs a ton; I can't lift it; I had to drag it home on a hand truck.I'm going to reattach the head, and create some sort of base to hold it upright, which will have to be substantial. I suspect it was so heavy that the feet cracked and gave way, causing it to fall forward and breaking it. Concrete is not my forte, so suggestions welcomed.
I'm not sure that you should do anything until you find out what you have from someone who knows about such things.
When you do figure it out, I'd try some polyurethane adhesive once it dries out. Clean the surface, keep the glue line thin. It tends to foam a little when it sets from the surrounding humidity, but wait until it sets to trim it off with blade. If you try to clean it off while it's still gooey, it will just make a mess. It's pretty forgiving, you have some time to get it lined up.
If it's concrete it's not an original sculpture, it's a garden piece. I would use a hammer drill and a masonry bit to drill a hole in the neck and a corresponding hole in the head. A regular drill and masonry bit will work...but much, much slower. Use a 1/2" drill for 1/2" dia rebar or bolt, or something smaller depending on the size of the neck. Wet the matching surfaces and clean up with a soft wire brush, let dry over night or 24 hours. Get some epoxy quick patch cement something like 29 fl. oz. SikaQuick Patch....about $15.00 at Lowes. This is a two part patch for cement, drys in about 20 minutes. Follow directions on the patch. Coat the neck with the patch about 1/4" thick and put some in the hole. Add the rebar or bolt. Put patch on the head break about 1/4" thick and place head on the neck with the Rebar or bolt spanning the break. Clean off the excess in about 15 minutes. Allow about 24 hours to set.
That will certainly make a good repair, Sika products are very reliable. The only problem could be that if the statue is kept outside or in a damp place, within a year the studs will start to rust. Since rust occupies 13 times the volume of steel and produces enormous pressure, the surrounding area will start to craze and crack. Fabricating the studs from stainless steel or brass will prevent this from happening.
Quite so; there's a barely perceptible parting line on the right lateral aspect of the neck. It's a concrete garden statue, but a very well-made one, moulded off of a very nice and historically accurate statue. I just need to engineer some sort of base to hold it upright.
