My rosin is cracked, ways to fix it?!
Hi all, yesterday my Andrea Rosin cracked in half and I was thinking ?? how to fix it? Suggestions please! Thanks
IF it cracked cleanly in half, you could try warming the freshly cracked surface gently with a hair dryer and push the two pieces back together. Otherwise you can melt it down and remold it.
Thanks! Will take a look
How much of a crime is it to melt a bunch of fragments of different rosins together?
Not a crime at all, but if they really are different rosins with different characteristics you may be surprised at the result. You may hate it or you may love it.
I had a shattered cake once and contemplated melting it down, but was warned about fumes, so I binned it. Now I have more than a lifetime's supply, so if another gets smashed, I'll bin that too; although I only have one cake of Guillaume, so maybe I'll have to rethink that one.
Fumes? Fumes of what? When you melt rosin it smells like pine sap, so maybe you're getting a few naturally-occurring turpenoid compound up your nose. The kind you pay to have included in the formulations of your household cleaning products.
I was warned.
I've remelted rosin on the stovetop before - the smell was super pleasant. (I also had a window open nearby.)
Is rosin like chocolate? In that chocolate is actually in a crystalline state with 3(?) forms, and what form it solidifies into depends on how slowly it cools. If poorly tempered, it ends up as the wrong crystalline form, hence soft dull chocolate with no “snap” so you then have to heat it back up to a certain temperature, and try again.
Fix it by buying some new William Salchow rosin. :) http://www.salchowbows.com/rosin
I once melted a broken rosin cake in an aluminum foil-lined form using a toaster oven at 200 F. Afterwards it was indistinguishable in all practical properties, but the color was a bit darker.
@Rosemary, my understanding is that rosin is not crystalline. Rather it is amorphous (glassy). Over time lots of such materials will slowly crystallize, so the issue of crystallinity is an interesting one. On the other hand, amber, which is rosin that has undergone geologic transformation (including chemical degradation and polymerization reactions) is still glassy; it is not crystalline.
I second the Salchow recommendation.
"Doctor, help! My butt has a crack in it!"
I once used superglue to repair a cake of rosin that got dropped, breaking cleanly into two pieces. Many years later it is still in use.
Wow, Nate, it costs like 100$ ! Isn't a bit too much for a rosin?))
It costs about $10 not $100 at most places. I highly recommend it. Made in the USA in upstate NY!
$100 is a lot for a cake of rosin. But remember: Everyone on violinist.com claims they only use
Great minds ... ;)
Rosemary, It is, of course a federal capital crime to melt a bunch of fragments of different rosins together - There are 10 people on death row, at different stages, as I type - But so far, no one has been executed. Discussions are underway as to which gas to use when executions eventually do take place, but all seem to be agreed that the gas concerned must be rosin-derived, at least in part, because it needs to contain some sort of lethal agent. Think carefully about what you want for your last meal and what music you want playing as you depart this life - I would suggest Rosini ...
John you aren't even allowed to rosin your bow with someone else's cake if you use a different brand. That's merely a class 2 felony though. You'd probably just do a dime for that.
Paul, you'd 'ardly 'ear it if the 'air ain' rosind!
