Old Jars

I know now for myself on the words of the Lord, when He spoke about putting new liquids into old jars, is true. Having blown-up no less than six (6) old jars in my caner over the past three (3) days. The contents have been varied but the results have been the same. BOOOOOOOM! It is not just the time I feel has been wasted or the produce that cannot be salvaged. For me it is the mess I have to clean up. Arghhhhh! Now I must figure out what I can do to fix this problem. Anyone have any ideas.... besides not using old bottles or checking for cracks or imperfections. Because I am doing that. I hate going out and buying new bottles because they are so darn expensive. Oh well back to the kitchen I have peaches and pears to do. Cross your fingers and say a prayer because it will be a roll of the dice on the next batch into the water.
