No Glassware Returns

Glassware cannot be returned for any reason; this is for your safety and ours. It would be prohibitively expensive to test for bacteriological, chemical or radiological agents since there is no way to tell if glass has been contaminated just by looking at it. We would have to throw it away even if you claim to never have opened the package Call first if you are unsure of what you need.

If the item is clearly defective, either heavily bubbled, chipped or with really bad markings, send us an image & we will refundyou.

Instructions/Safety

Safety Disclaimer-Warning

Handle glassware with care & wear goggles & gloves because:

  1. Unless you poured it yourself, assume any liquid is hazardous.
  2. Hot & cold glass looks the same & does not have to be red to cause burns. Unless it was in the freezer, assume it is hot.
  3. Borosilicate glass will withstand a fair degree of thermal shock but unless your intent is to see if you can make it crack, don't toss recently heated glass into a cold water bath.
  4. When borosilicate glass breaks, it makes sharp edges like any other kind of glass. Dispose of pieces carefully.
