Pretty cool with a few takeaways… Boy I’m glad I live here. Stock up on shellac even though I hardly use it… If they’re introducing fungicides in production it may be less non toxic, possibly… Does anyone know if unmixed shellac has a shelf life? |

The more refined grades like Blonde have a limited shelf life. It's hard to give a specific time frame. In time Blonde will take weeks to dissolve or leave undissolved slivers in the mix. I have some seedlac that is over 40 years old and still works the way it always has. Button has a good shelf life but whether it will approach seedlac is unknown to me. |

From what I understand shellac flakes have a shelf life of about 3 years. Assuming you're storing in a cool dark place. |

Excellent video, and timely. I recently did a shellac deep dive due to some pitch reside (corns on the paper) on a Sitka on my current build. Its a long story, I almost started a thread to ask about it... TRein wrote: The more refined grades like Blonde have a limited shelf life. It's hard to give a specific time frame.

Assuming you're storing in a cool dark place. Blond shellac FLAKE shelf life was new learning for me, thanks David and Tom! Ron of Shellac.net confirmed 1 to 2 year shelf life if stored cool and dry. Ron told me if it was "older" flakes, to mix a bit up in 2 lb cut and do a standard shellac test; 8 hours on glass or equivalent then thumbnail resistant- or sands to dust on wood). Thanks for the video and the thread. |
