Pirastro Tonica Rosin fissures
a quick question. I've been busy last 2 weeks and couldn't play the violin. Yesterday I played and when I opened the case (oblong, wood) and opened the rosin box, I noticed there were fissures all around the cake, and the shape was a little deformed. The violin was also a little of of tune, like a quarter of a tone lower.
The temperatures lately increased noticeably, but last summer I had the very same case, violin and the same rosin, and this did not happen. I guess it's because the temperatures, that have "melted" the rosin, but sounds a little "scary", besides, last year this didn't happen.
Do your rosins also get deformed during hot periods?
What do you do about it?
My rosin becomes slightly moldable when rather hot outside, but not to the degree that it needs any treatment.
Yeah, mine can be used perfectly, it's not damaged, but I just got kind of shocked when I saw that it was deformed and there were cracks around the cake. I've never seen it before, and I want to know if it's a normal thing.
I ask about such rosin issues and Dennis R suggested placing the rosin with the cloth flat on it, on a flat surface, with a heavy book on top. I did this and the rosin is now flat ( and a little fatter).
Oh, so you try to bring it back to its original shape by using also the high temperatures of summer?
Yeah, old rosin does get brittle. I especially noticed that with the obligato that I was using. It did the same thing , then shattered one winter (dry). Do you love it? If so, just get another cake, otherwise try something else, like Millant.
Thank you, Edward, nice reply.
Rosin is tricky Tim,
But, when you buy a rosin, it will long for decades. How are you supposed to compare them?
Yeah, that's what I thought, but that'd be a total waste of rosin.
Hard rosin is less grabby than soft rosin, and lighter rosins are less grabby than dark ones (less of the resinous part of the sap that is sticky). :)
So, if I want a very punchy spiccato I should use a soft dark rosin?
For the stickiest rosin available (meant for historical THICK plain gut, the E being 0.7 mm!), Aquilausa.com has an order form for a cake of it for 18$ US. :)
You can also try Viola/Cello rosin, if you need something even sticker. It's not going to hurt your instrument or bow.
Especially Pops Bass rosin-the stuff approaches liquid in a hot summer, I could mold it in my palm. :D
Wait, violin and viola rosin are two different things? Why? How?
