Wilkinsons is a great place for lye. Home Products Caustic Soda I believe. This is where I spotted it, and got very excited. There's a home brew place that does sodium hydroxide, in liquid bottle form, to calibrate PH meters, though I'm not sure about it's purity, it was just called Sodium Hydroxide Solution. I don't know whether the solution part merely points out that it was liquid form, or whether that implies it's diluted to some degree, but if it's for calibration or some such, I imagine it's pretty pure, but the bottle may be small for the price however. Not that it matters, becasue Wilkinsons is the place to go. As your a fellow UK dude, Behlen Naphtha might be something to add to the list, though I'll be more sure after I've tried it of course. Anyway I've got an introduction essay to write myself, so I better get on. Good to see another UK dude. Thank you also to DMT-Nexus. I've been an avid reader of these forums for quite some time, but today was compelled to join. It must be my time. I shall be writing my introduction essay right now. Good luck fellow brit, let us bring a bit of blighty to hyperspace, and a bit of hyperspace to blighty.
