Work collapses during enamelling

Also because it alloys rapidly with the surrounding base metal it
is fluid for only a split second, after that forget it, you will
not be able to reflow it. Jim

Can you tin a part with it and then solder later, or does it alloy
too fast?

It does not reflow well, it will depend on the specifics of the
piece but it is not a good choice for such use.

There are a few solutions: If you want to solder on to the
non-enameled side you need to use hard solder as the flow point of
the solder is hot enough to re-flow the enamel, if you use a softer
flowing solder your enamel not reach a high enough temp. thus
cracking. If you want to solder before enameling you need to use a
hard, IT, or eutectic solder and protect the solder joint with
yellow ochre or white correction fluid. I prefer Hard, it allows more
flow control than the other two.

Thanks to the wonderful teacher Linda Darty for that one.
