Formula for top coat French polish - my recipe book in storage

Recommended Posts

I ran out of my top coat spirit varnish.  My formulas are in a notebook that must be in storage.  Hazards of a tiny workshop.  

I know it had benzoin, mastic, lac blah blah, just don't remember.  

Got a good formula that will bond well to oil and go on nicely?

Thanks much.

This is what we did in the IU shop:

45 grams seedlac
5 grams gum mastic
5 grams gum sandarac
5 ml. lavender spike oil 

200ml Everclear 190°

 

Put it all in a jar and shake vigorously twice a day for a couple minutes at a time. It will take anywhere from a week to a month of this for everything to go into solution. 

 

Once it has, put it in a double-boiler and boil for seven minutes. Take it off and let it cool for fifteen, then put it back on and boil another seven. While still warm, strain. Once cool, it's ready to use. You may have to add a little more Everclear to thin it, as some is lost in the boiling.
