  1. Was ist das? (German cello)

    If this was a violin I would say a few hundred euros. But then you find those instruments for a lot more: ... which I would never pay for this. If it is in good shape and makes a good sound, a German cello of this time, I would say should sell for EUR 2000-3000. But then you will find shops that would charge more (>$5000): Auction prices are about half of the prices charged by dealers. As with all sales, the item is worth as much as a nuyer is willing to pay for it, and you need to find the buyer.
  2. Cleaning rosin & gunk for violins with acetone

    I am a chemist, I know how to handle acetone. And the text above means more or less it is not very toxic. After all your body produces acetone. This is what causes the bad breath when you go on a keto-diet.
  3. Tarisio Certificates

    Don't they give a guarantee of authenticiy anyway?
  4. Cleaning rosin & gunk for violins with acetone

    Acetone is definitely ok to remove rosin deposites, and it is not toxic, just highly flamable. I would be somewhat more careful with a spirit varnish. What has always worked is Xylol - now hard to get. What works really well is petroleum, which is a mix of substances, available as lighter fluid.
  5. Collin-Mezin cello?

    This Collin-Mezin is not one of the mass-produced ones. I would assume he used an inside mold.
  6. No Label but drop of blood

    If it is Mirecourt it has higher linings and more square shaped blocks.
  7. Oil varnish shelf life

    Oil varnish does not behave like ethanol or acetone. It is not air, but it is light sensitive. Light will generate radicals at the conjugated double bonds of linoleic acid, alpha-linolenic acid, and the abietic acid from rosin. Air will have little influence. In a chemistry lab one would wrap a container of such vanish in aluminum foil to avoid light exposure.
  8. TotalEnergy Tuner. With this app you can even record the spectrogram of your fiddle. Used it for a long time and like it.
  9. Violin neck finish by Hill's (ground?)

    Danish oil is tung oil. Boiled Danish oil will polymerise like linseed oil. Tung oil can be use to make varnishes like linseed oil.
  10. Nicolaus Amatus fecit in Cremona 1662

    Many cities were renamed when as Europe was 'rebuilt and reshaped' after the Yalta conference. Germans are very hesitant to use the old names of these cities and Czech people would also not be happy with this. You read Schönbach a lot here from English violin makers and dealers one of who settled in Austria :). But Germans would never call it Schönbach nowadays, this is like calling Lubliana Laibach. As a German, I always avoid to talk about Schönbach. The use of the 'Made in Germany' label in the Soviet Zone / DDR was in my personal view as valid as to use this label in the BRD. There was always only one Germany, this was the official line taught in schools, and luckily the two parts came back together.
  11. Gand & Bernardel violin 1887 ID?

    Clearly not Gand et Bernardel. Doesn't look French either.
  12. Opinion about this Ebay violin?

    I don't understand why he doesn't sell it for what it is: a mocked-up Chinese violin. If it sounds good it might sell as such in a similar price range.
  13. Arching

    I guess there is nothing that hasn't been tried when it comes to fiddles.
  14. Arching

    It is good to discover something new every now and than. I also call myself Outis sometimes. What do these instruments with flat tops sound like?
  15. Violin with ribs let into the back

    Is this feature of ribs let into the back not attributed to early Füssen makers? Pamphillon also did it. We know little about these makers and their instruments are difficult to identify.
