No earth in old lamp

[StillLearning4]

Thanks in advance for any help.

I've got an old lamp (inherited from my gran) that I want to add a switch to and lengthen the wire. It doesn't have an earth and I was wondering whether that's okay? I've read about double insulated appliances but I think this lamp was probably built before they existed and I can't see a box inside a box anywhere. It's made out of some sort of stone or porcelain.

Do you think it's safe? Or should I put a new wire in it?

Cheers!

It doesn't need an earth.

Cheers pal. So I could happily get some twin core (75mm?) and a switch and add that in no problem?

Yes 0.75 two core is fine.
