Enjoy the pleasure of cultivating the perfect sourdough starter! This 32-ounce fermentation jar, designed specifically for sourdough baking, is made of high-quality borosilicate glass. 

Features:

• Featuring an upright body and smooth inner wall design, unlike traditional Mason jars that curve inward, this design allows the dough to expand evenly and is easier to observe.
• The wide-mouth 4-inch (10 cm) design and rounded bottom make it easy to reach and stir without any hard-to-clean corners, greatly simplifying daily feeding and cleaning steps.
• It comes with an adjustable black silicone marker ring, which, along with the bottle's inch and centimeter scales, allows for precise tracking of fermentation progress and the optimal time for gold application.
  When paired with a special breathable plastic cap, it can effectively prevent excessive air pressure while maintaining perfect air circulation and protecting yeast from external bacterial contamination.
• Both the bottle and the lid can be completely placed in the dishwasher for washing, and the glass jar is also microwave-safe (the plastic lid is not microwave-safe). Daily maintenance is worry-free and effortless.
