  1. I use bioethanol in bow alcohol lamps and for dissolving shellac etc... its cheap and never had a problem with it. being in the uk the ingredients will vary a little than in the US but e-NRG are based in LA and their`s is 92% ethanol 8 % isopropanol. https://e-nrg.com/
  2. Martin its temperature when soldering is slightly higher than sterling silver. Ive never had any problem soldering gold.Though it is a little tricker since cadmium fluxes/solders were banned which worked great and at a slightly lower temp but now well known to give off nasty fumes.
  3. should be a relatively easy repair removing the ring , soldering ,tidying up carefully especially the collar area and refitting it.
  4. Not Simon, looking more towards CN Bazin, Cuniot or Ef ouchard , seen this type of bow from these makers before .
  5. The bow looks like possibly a Nicolas Simon
  6. The measurements etc are on the reverse/back of the poster which im kind of guessing you dont realise??
  7. Apart from its not Katalox, ive used katalox quite a bit and its not good for bows and doesnt look like it . Though it is a species of Swartzia of which there are many and even same species can look different depending which region its growing in.
  8. Do you have a photo of the frog and pearl slide? Heres an ironwood Simon school/workshop bow i have , most probably Wamara ironwood. The grain strips look different depending on how off quarter the bow head is . Often relatively straight looking on one side of the head and quite wild on the other side.
  9. Looks like one of the swartzia species from south america to me ,had loads of bows similar , often has a reddish tint depending on the finish and species.
  10. It shouldnt be too difficult a repair for a normal violin repair guy. Cleaning the break , gluing it back and probably grafting in some new wood and retouching on the outside .Maybe a bit of re-enforcement of the crack inside with something like linen. I assume it red cedar and carved out of a solid piece. You seem quite a talented multi instrumentlist, good luck
  11. Early pre 1901 (i think) HR Pfretzschners were often unstamped with no Saxony coat of Arms on the frog.
  12. Im in the UK ,but the markers look interesting for other uses. But is this a joke or are they really so expensive. https://www.homeloft.uk/products/mohawk-m2671208-promarktm-touchup-markers-12-pk-730in-x-700in-x-170in?gclid=EAIaIQobChMIt6q_3Jri8QIVjGpvBB0SvgY9EAQYBCABEgKltvD_BwE
  13. I have these that i use for touch up of old oil paintings (very fine pigments in paraloid 72) ,alternately with laropal and pigment mixes that i make myself. I have used them occasionally for touching up old instruments and they work quite well once you learn how to control the glossy look of the paraloid. Quite expensive though.
  14. Does no-one use paraloid 72 or laropal resins in touch up??
  15. From my understanding , fossil amber is a fully polymerised resin which is why it is difficult to dissolve in oil etc... By heating all your doing is decomposing the resin( ie ruining it) . It has no relation to the initial amber when cooked like this .But would end up more like a hard copal varnish. If you wanted a film of amber you would dissolve straight into something like Chloroform or Dichloromethane ,then it would be basically a spirit type varnish.
  16. Looks awfully rough and unfinished . Why are the jaws curved like closing clamps????
  17. Theres some photos of their jigs etc.. on their facebook page
  18. Heres one ive just photographed next to two pieces of turtle shell. nB. i just remembered why the result of the turtle shell appeared like shellac, its because it was from an antique turtleshell and was probably varnished with shellac. (hence the tan/orange colour) Ive added another photo with some of the shellac varnish removed and it glows more like it should very similar to dried animal glue protein
  19. Thats just the solder line you can see , its often visible on old bows ,the solder often tarnishes differently and you can see more of it because the ferrule hasnt been carefully filed when made. Its far more noticiable on nickel /maillechort mounts.
  20. With regards to certificates like this , it is NOT cast iron, but an opinion of said authority. Whether the bow is what it purports to be is his opinion and NOT a 100% certainty that it is correct.
  21. Take lots 94 and 100 , both with respectable certificates but listed as just `a violin bow`. They operate in a strange manor ,does this mean Tarisio dont agree with the certificates or what??
  22. You probably know far more than me about Turkmen rugs/textiles,etc... I was just making the point that it was available relatively early on. I maybe should have said that it was commonly available if you could afford to purchase the pre dyed wool/silk or the actual dyestuff !
  23. Hi, There are examples of Mexican cochineal in Turkmen textiles as far back as the 16th century , it became pretty common in usage by the 17th century. They probably had access to Armenian, Arrarat ,Polish etc.. cochineal before that.
  24. Heres one i saw at auction 20 years back supposedly by Marcel Pichler, it was owned by Joseph Szigeti .Sorry for the bad photos but it was 20 years ago.
