I'm choosing to call these vintage rather than second hand so as to sound all posh. They cost the grand sum of 10p each at a car boot sale back in the summer. I had the screw bands refurbished at KilnerjarsUk for a further £2.50 each so not a bad price for the beautiful greeny, bubbly glass jars.
They have old fashioned 2 piece glass lids but no maker's mark. Kilnerjars Peter thinks they're probably cheapo Woolworths copies of Kilner/Mason jars. I have to admit I'm a bit too nervous to use them for actually bottling as I'm not sure if the old glass will stand up to the pressure with it's various flaws etc. I'd also need buy rubber bands and they, rather frustratingly, are all very slightly different sizes so I'd have to buy a pack of bands for each jar which would bump the price up further, plus figuring out which size to buy would be a bit hit and miss. I will therefore be keeping these for storage and pickling.
I was rather pleased to see Ruth on the Edwardian Farm using jars of the same design for pickling her apples the other week - though I was desperate to tell her to pickle damsons rather than apples as they're so much nicer!
