How can a person Insulate copper wire in a medieval world?

Time traveler here, stranded in the year of 1019 AD, medieval ages. Location: europe. While I can still access and post on web forums because my temporal transmitter has a 1Ky range, I have a broken solenoid. Thing melted down and it is part of my flux capacitor. And as a security measure my ship locked down and unaccessible until I can fix the solenoid. Stupid military protocols.

I am without access to any technology, just my portable temporal communicator (what you guys in the early XXI century would call a cellphone). I have to make do with tools and techniques from the locals.

I need to create another bobbin and all I have is copper wire. Naked copper wire and I don't need to tell that it would short-circuit the solenoid. Is there any way I can insulate the wire to repair my solenoid bobbin?

Many thanks.

_{P.S.: Don't worry about paradoxes. Nobody will believe this post is from a real time traveler.}
