About my Blue Glass Bottles

• Important information on using Blue Glass Bottles and keeping them from breaking! - I will replace bottles that arrive broken, however, I cannot replace bottles that break after they're used. Follow these guidelines to insure the long life of your bottles.

• Size: The bottles are 12" tall with cap in place, and around 11 3/8" tall without the cap in place. They are approx. 4" in diameter at the base... there is a taper that goes in just above the base and then back out to approx. 4" in diameter just below the neck.
• Glass: They are Cobalt Blue Glass. The manufacturer states that these bottles are pressure rated at 125 PSI, if the internal pressure goes above this amount, then the spring/washer will release excess pressure. The manufacturer also states that they have beverage producers actually pasteurize in these bottles, so they're tough. Follow these guidelines to make sure your bottles do not break!
• Tops: The spring tops remove from these bottles (the end of the springs fit into a small indention on either side of the bottle top - these indentions do not go all the way through the glass). If you don't want to use the metal spring, you can simply remove the tops and use these bottles with a cork or plastic wrap. See photo at the bottom of the home page.
• Lead Content:
• I've had customers ask about lead content and purity of the glass used in these bottles. Glass is inert and does not leech. You will not get lead in your water from the glass. The only way would be if you ground the glass down to fine powered and digested it, then you could possibly absorb the small amounts of lead in the glass, because your stomach acids would have dissolved the glass.
• All glass that uses any recycled material has detectable amounts of lead in it. This is pretty much all glass bottles, whether produced in the US, Europe, Asia or anywhere else. The only way to get glass without detectable amounts of lead is to produce it from pure batch materials, which is called superflint, and costs quite a lot. I don't know if you can even make colored glass from pure superflint, all that I know about uses recycled glass in the mix.
• EU has formal regulations on acceptable amounts of lead, which is 200 ppm. To my knowledge, the US doesn't for container glass, though the industry standard tends to be around 100 ppm or less for flint glass, around 200 ppm or less for colored glass. The current manufacturer of these bottles is in Canada and uses manufacturing facilities around the world... one of their suppliers, Taiwan Glass for example, has 4 furnaces and tests production from one or two furnaces pretty much every day, rotating between them so each furnace gets tested a few times per week. Lead is introduced through the recycled glass (called cullet) which is the largest component of glass, if the plant finds the lead levels rising on a furnace, they reduce the cullet amount.
