How To Open Pop's Rosin Cake

1. This is excerpted from a Facebook post past IU prof. Kurt Muroki:

   Kurt Muroki best way to revive old pops or any other rosin for that matter is not with humidification... The best mode is alcohol. Put a quarter size amount of alcohol-based hand sanitizer or 50/l rubbing booze and water in the bottom of a small Tupperware container, put the rosin in a pops rosin container with the lid open up, or any other method that does non let the rosin to touch the booze. Exit overnight and your rosin will be soft. Leave information technology for 2 or 3 days and y'all can cascade your rosin on your bow.
   ​

   Haven't tried it still, but I've got a couple of powdery Pops cakes that are skilful candidates for the experiment. I'll post results.

2. I accept a roughly xl-year-old cake of Pops that came with my Mortone. I may have to put this to the exam tonight...

3. Okay, I tried this overnight, and information technology works remarkably well! I rejuvenated a cake of Pops and a cake of Kolstein. I put them into sealed Tupperware canisters with the l/50 solvent mix of rubbing booze and h2o and left them from midnight to six:45am. The tops of each cake were dramatically softened—then much so that I wouldn't utilise to bow hair in their current land. I'll exit them in open canisters for a while to harden a flake.

   So be warned: Don't overdo it! I probably should've checked on the cakes afterward the kickoff 4 hours. A couple of things I don't yet know:

   1. How deep into the cakes the solvent penetrated and softened; and
   two. How well it will work on the bow hair and strings
   ​

   Please post your results hither...

4. I'll know when I go home from work. I've got pops in Tupperware with a quarter sized pool of mitt sanitizer. By the time I go home it will exist simply shy of 24 hrs

5. Son. Of. A. Gun. It looks similar it worked!

6. Aforementioned here, I wish I did a before and later shot. I had the aforementioned result equally the OP in that my cake is style too soft to use at the moment so I'm gonna leave the cap open for awhile.

   Thanks for the tip! I can't believe it worked. Every bit fiddling as I bow, I'd hate to supercede it every time information technology dries out.

   mrbaloo and csrund similar this.

7. I accidentally discovered the outcome of alcohol on rosin when I substituted 90 pct booze instead of h2o on my pocket-sized square of sponge in my dwelling house fabricated Ball canning jar humidifier for rosin. It got mucilaginous and gooy so I threw it out. I didn't recollect to let information technology dry.

9. Wow; this really works, and speedily (only took nearly an hour!). With the amount of bowing I do, I won't need to buy any rosin for the next 10 years!

10. Yeah, as with others I've found it works not bad and overnight is overkill. I am on tour and grabbed an old Pops by mistake. I had the 50/50 alcohol to clean my strings .

    I followed the instructions and had soft as fresh Pops in a few hours.

    Good find.

11. The block I experimented on is at least thirty years onetime so 24 hours was barely enough.

12. 24 hrs was overkill... I left my top open up all solar day and I could still leave a fingerprint on it with a gentle bear on

    Great find! Will sticky this....no pun intended.

14. I'k no pharmacist but through years of private written report I tin confirm that alcohol e'er works meliorate than h2o

16. My estimate is that booze is a solvent of rosin. When yous put information technology in the container, information technology evaporates and a bit of the booze vapor gets absorbed past the rosin.

    Another guess of mine would be that other solvents like thinner, mineral spirits, etc. might work likewise, but you may need to dilute them even more since they're probably stronger than alcohol. Booze seems a safer alternative.

17. Living in Canada I take had my rosin frozen and melted, simply at room temperature information technology seems still to retain its qualities - or am I fooling myself?

18. I call back 50/fifty is an appropriate dilution ratio.

    I would think information technology may be possible to put 100% alcohol in the container, just just the aforementioned corporeality as you'd use in the 50/l ratio. My gauge is that the rosin is not arresting the h2o from the vapors, only the alcohol.

    I'grand a beginner at double bass and my cake of pops rosin is still fresh, so I haven't tried the experiment, merely I'll sure proceed this great tip in mind for when the time comes to revive it. Thanks for sharing!

19. 50% nail smoothen remover (don't ask..) + 50% water - softening on Pops and old Neyman (imperial container) within i hour..

    Wow, tip of the twelvemonth??

20. Which smash polish remover? Acetone is the traditional solvent, just most are now synthetics. It seems that lots of organic solvents will work for this. I'k very happy, as I have a agglomeration of dried up one-time cakes of Nyman and Carlsson which I luckily never threw away.
