For paints, VT gives an enamel gloss and strengthens the paint film. It is also used in violin varnish. I would expect that for horses, it would be used to shine up hooves for show. For our purposes I would expect that it provides shine and strength to the shellac. I have had problems with finish wrinkling due to cold or heat, one of the reasons why I am buying these ingredients.
and another one to polish Helmets and Cartridge hangers (same book, same page):
Prepare a saturated solution of bleached shellac in gasoline. Add Nigrosine to make it deep black. Next, let the lacquer settle. The finished lacquer (attention: it‘s flammable) will be applied carefully and evenly thinly by using a soft sponge.
When repainting, the old lacquer is previously sanded off with pumice. The paint generally dries quickly and gives a pitch black sheen.
thank you for your additonal recipe, but would you please add the contemporary source? Intention of this post was to conserve original recipes of Pickelhaube-Lacquers, from the time of manufacturing. I believe that these helmets are history and when restored, they should be restored as original as possible. That's why I started this post, to help that restorations could be as contemporary as possible. It's not just the look of the helmet which should be conserved. Thank you again.
Dear Sandmann, the recipe comes from a German art restorer born before the war, who was told the recipe by his father, who worked around 1910 in some manufacture. After the war he stayed in Poland and worked as a professional art restorer.That's all I know,but I will try to find out more.Regards Wojtek.
The backing recipe from Sandy was slightly modified.Paper glue was mixed with wood glue and water was added.The whole thing was mixed and black from the vine was added.Three layers were applied with a paint roller.The polish scraped off the helmet was dissolved in spirit and applied with a paint roller and polished with pumice stone dust.
Ah ok, I thought the left picture shows the polished finish . In this case the result looks great, well done
Wojtek, have you also seen the variations of the leather lacquers below my last recipe, on the following pages? Very interesting with wax or Asphalt to get a slightly thicker consistency.
Sandy we are using your 1845 recipes with a colleague.We are testing three recipes and the results are promising.When we finish testing I will do a full description and send you pictures.Regards
