Pitch Varnish
« on: November 20, 2014, 08:26:39 pm »
I've made pitch varnish using paint reducers and lacquer thinner. I thought I would try it with methyl hydrate(methanol,wood alcohol). I put a lump of pitch in the MH and after a few hours it turned white. It looks like it's not completely dissolving. Does anyone know if this is normal.

Mine did the same in Alcohol when I made it. It took awhile to completely dissolve.

Thanks Jo. I'm just to impatient I guess.

I use denatured alcohol and it always dissolves to different shades of amber(depending on the pitch) from dark to light but never turns white or milky.

It's just the surface of the pitch lump that turned white. The part that's dissolved is a nice American beer ;) ;) color. If I scrape the white stuff off the pitch lump it seems to dissolve eventually. I just never noticed this when using mineral spirits and wondered if maybe I shouldn't use methyl hydrate. I think it will be fine in a few more days.
