I purchased an Osma two-pack of alum block.  One came intact, the other is broken into three pieces.  Is there a way to fuse them back together?

I'd like to know as well.  I broke my alum block and just assumed it was like Humpty Dumpty, it would never go back together again.

Not sure if this will work but try wetting the two pieces where they will join and then wrap a rubber band around it. Let it set for a couple days. I’m thinking that maybe as the joint dries it will fuse itself back together. I’m no scientist but I’d give that a try.

I just hope it works. Never tried it myself.

I have yet to hear back from the seller.  Not sure how they will resolve this.  So, if need be, I'll try this method to se if it mends the block.Smile

I've tried it with the water/rubber band and in my case it didn't work.  When I drop and break an alum (always) I smooth off the very sharp edges and use for travel kit alum/deodorant.

No idea if they can be fused back together but if the packaging was inadequate or questionable then I'd certainly ask the seller for a new block. 
If it was adequately packaged... well, then I would ask very nicely for a new block.

I've never done it but alum has a melting point below 212F degrees.  Put it on a double boiler, melt it down, pour into mold.  And if it works let us know.

I've seen a few YouTube videos on this process and it results in less than stellar outcome.   However, I'd ned to explore and research the process a bit more.  I'm still leaning toward fusing with water.  And, still waiting to hear from the seller.

Here's an update.Smile

It didn't work.

Okay, now the details:  The seller never responded to my emails.  So, I took it in stride thinking I'll just go forward and do a repair to see what happens.

I wet the block pieces and then reassembled them.  I wrapped a rubber band around it to old the pieces together. I tried to tighten it down (doing a double wrap of the rubber band) but to no avail.  The pieces kept slipping past one another.  I then just reassembled and stuck the pieces together and let it set up overnight.  

The next morning, well, it just didn't hold together.  I doubt a rubber band wold have made much difference. 

So, I'll just use the large pieces here and there.
