As for fake borax - depends where you bought it. There's non-borax sold as a substitute for laundry use (EU ban on it) and that won't work, but the real stuff is readily available from jewellery/forging/chemical supply places.
Thanks so much for all your responses, I really appreciate it. I’ve been away so it’s taken me a while to get back on here. The torch is: Autostart Blow torch AT2071H.
