  1. Ouch. Poor player, I hope she is OK. If she was particularly fond of the instrument, this must have been quite a traumatising experience.
  2. Do you mean cloudiness in the varnish film, or in the actual mixed varnish in the pot?
  3. Hi Don, great to hear from you, thanks for sharing your experience. Did you ever try mixing a bit of Copal into the Rosin varnishes to make them more durable? That's what I'm experimenting with at the moment. It looks promising on the test strips. How it will look in 10 years time is a whole other concern.... Hence my posting here, reaching out for advice! All the best to everyone.
  4. The dried film on my test strips appears to be very nice and clear, so this is a good sign. Has anybody on here ever tried this on an instrument? How were the results?
  5. Hello folks, I have recently been experimenting with mixing in a bit of Copal varnish (10% - 20%) to my Colophony/Linseed oil varnish, to add a bit more hardness/toughness and to make the varnish a bit more wear resistant. The Copal varnish I am using is a very good one, made by James Groves. It is Very high in copal resin-content: 50% copal to 50% heat-polymerized linseed oil. I am mixing it in cold to my own cooked varnish (50% Colophony to 50% Linseed Oil). This seems to have worked well on my test strips, and it does seem make the varnish a bit tougher. However, I am concerned as to how this may fare in the long term - could it cause the varnish film to crack due to Copal's reputation for being brittle? I'd love to hear from anybody who has tried something like this, or who has experimented with mixing a bit of copal into their Pine Resin/Colophony & Linseed Oil varnish. Best wishes to all on this wonderful forum!
  6. Very interesting. Where do cooked down Larch Turpentine or Strasbourg Turpentine stand on the hardness scale (with Amber being the hardest)?
  7. Ditto this question. What about cooked down Larch turpentine resin?
  8. Agreed with Davide - what an absolutely brilliant post! Thank you, Mr Piolle for sharing your wisdom. Would you happen to know anywhere that one could buy this 'Bijon'?
  9. sadly they do not sell Strasbourg turpentine anymore (and nor does anybody else...)
  10. This would be very interesting to read, I agree. I have not seen a thread discussing that on here before.... Larch Turpentine is (rather unsurprisingly) from the Austrian Larch Tree, Larix europaea Strasbourg Turpentine is/was from the Silver Fir Tree, Abies alba
  11. What benefits would (uncooked?) Larch turpentine added to a varnish made of Raw Resin bring?
  12. This looks attractive for a nice clear varnish, Joe. Do you sell a type of Larch Resin varnish? How do you find this compares to your Greek Pitch varnish (color aside - I'm wondering about hardness and wearing properties).
  13. Great advice all, thanks for contributing. Jackson Maberry: May I ask, how long did you cook your Larch for to get a good colour?
