    Extracting a yellow pigment from aloe

    Hi Uncle Duke I had no luck with the Aloe Socotrino leaves. Very few drops fell down from the cut I made on the leaves. And the worse thing I lost that few yellow tears I collected. So, I begin now by second time. I will inform to Maestronet. Regards Tango

    Varnishing with spirit varnish (sealer?)

    Hi Ctanzio I have two jars full of plaster prepared like Roger Hargrave explained in his Making a Doubble Bass. May I use that PoP in the way you wrote? Thanks for explanation Thanks for reply and thanks Joey too

    Varnishing with spirit varnish (sealer?)

    Hi Ctanzio Saturated means : "with more water than plaster or more plaster than water"?
  8. Hi all I am thinking to varnish my next violin with spirit varnish. As I always sealed the wood with plaster of Paris and oil and then varnished with oil varnish, I am in doubt if this would be a problem. Do you see any problem about that? I could change to plaster with water Thank in advance Tango

    Colophony as Coloured Sealer before ground and varnish

    Hi Francesco I sealed the wood with Plaster of Paris and colophony oil varnish. This varnish have a beautiful subtle yellow hue. In the last violin some zones appeared some dark. May be it was my fault but I think that in the next I will seal with a more clear varnish for precaution. Regards Tango

    Hi Conor Second coincidence in the in the night I guessed that a thick central zone of the back bring some inertia. Being thin it would be difficult. Very clear the analogy of the knife.
