I wanted to make a new attempt with propolis soap fulton 

 

I thought that I remember how to do 

 

The formula is 100 gr propolis resin 300 ml water pka 3 g KOH solution, then with alum. 

 

I forgot to give 300 ml of water, and gave KOH straight to propolis heated in a water bath. Then I put in a hot solution of alum. 

 

Hu, boo, ouu originated clotted mass as Vaseline, displace water. I decanted water. 

 

Further warming, but grease is already in a water bath (100 degrees Celsius) a more softened zřemě it got much higher melting point than propolis. 

 

Insoluble in water. The turpentine-insoluble, alcohol soluble. 

 

After dilution with alcohol on wood very impressive per hour dry and not sticky. 

 

 

You do not know what I made​​? Fulon propolis soap that is not for sure.

Propolis can be used as an ingredient in varnish and was mentioned at least as early as 1788 in a compilation various authors, and in particular, of Bonanni's works, by Agricola.  It was discussed in "The 'Secrets' of Stradivari," by Simone F. Sacconi in the 1970s.
