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.
Glass: They are made from Cobalt Blue Glass. The manufacturer states that these bottles are pressure rated to 125 PSI, if the internal pressure goes above this amount, then the spring/washer will release the excess pressure. The manufacturer also told me that they have beverage producers that pasteurize directly in these bottles, so they’re pretty tough.
Tops: You can remove the spring tops from these bottles by pulling out on the springs away from the bottle (the end of the springs fit into a small indention on either side of the bottle top). If you don’t want to use the metal spring/plastic top, you can remove the top and use these bottles with a cork or plastic wrap. See photo below.
I’ve had customers ask about lead content and purity of the glass used in these bottles. You will not get any lead in your water from 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 a fine powder 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 pretty much covers 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 spoke the manufacturer and they don’t know if you can even make colored glass from pure superflint, all they knew about uses recycled glass in the mix.
EU has formal regulations on acceptable amounts of lead, which is 200 ppm. To the manufacturer’s knowledge, the US doesn’t have regulations 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.
Please Wash Bottles before Use!!!
NOTE: We will replace bottles that arrive broken that were damaged in shipment, however, we cannot replace bottles that break after received in good condition.
- Leave an inch to two inches of air at the top of the bottle to allow for temperature changes.
- Do not expose the glass to sudden changes in temperature… this WILL stress the glass and brake the bottle. It may not happen suddenly, but over repeated cycles.
- Do not fill a hot bottle with cold water, let the bottles cool down first.
- When you take the bottles outside and the bottles are cold, don’t place them on a hot metal or wood surface, instead, put something like cardboard or a cloth under them.
- This applies to bringing them inside… if the bottles are hot, don’t sit them directly on cold granite, marble, or other such surfaces… put them on something like a pot holder or cloth until they cool down.
- The reverse is true too, if it’s cold outside, don’t bring really cold bottles inside and sit them directly on a hot or really warm surface…
- Obviously letting a bottle with any amount of water in it freeze will result in a broken bottle!
Please Forgive Me, I’m Sorry, I Love You, Thank You
