Artcome Fermentation Kit for Wide-Mouth Mason Jars — 28-Piece Set with 5 Stainless Steel Lids & Glass Weights, Airlocks & Silicone

The Artcome 28-piece fermentation kit is a complete set of stainless-steel lids, airlocks, glass weights and silicone accessories designed to convert wide-mouth mason jars into reliable, reusable fermentation vessels.

Whether you're making small-batch sauerkraut, pickles, kimchi, or experimenting with new ferments, this kit gives you the hardware to control air exposure and keep brine in contact with your ingredients. Everything you need for up to five jars is included: five stainless-steel lids with built-in gaskets, five removable airlocks, five heavy glass weights, extra silicone rings and grommets, plus a silicone tong for safe handling. The components are built for repeated use, with corrosion-resistant metals and food-safe silicone and glass parts.

How do I set up the kit for fermenting in a mason jar?

Setting up is quick: screw a stainless-steel lid onto a clean wide-mouth jar with a silicone ring underneath, insert the airlock through the lid's hole, and add water to the airlock. Place your prepared vegetables in the jar, press them beneath the brine with a glass weight, and seal the airlock to let gases escape while keeping oxygen and contaminants out.

• Use included silicone ring under each lid for an airtight seal.
• Fill the airlock with water to create a one-way vent for CO2.
• Lower glass weight with silicone tong to prevent splashes and disturbance.
• Replace silicone cap after fermentation to store the jar in the fridge.

What materials and sizes are included, and are they durable?

The kit combines corrosion-resistant stainless-steel lids, heavy tempered glass weights, food-grade silicone rings and grommets, and a silicone tong. The glass weights measure roughly 2.75" × 2.75" × 1.37" and weigh about 200 g (7 oz) each—heavy enough to hold down vegetables under brine. These components are selected for repeated contact with salty brines and easy cleaning.

• Five stainless-steel lids resist rust and screw onto standard wide-mouth jars.
• Five glass weights (approx. 2.75" square, 1.37" high) for reliable submersion.
• Six silicone rings and grommets provide extra replacements for long-term use.
• Silicone parts are food-grade, flexible, and easy to sanitize.

How do I clean and store the components safely?

Most parts clean easily with warm soapy water or a quick rinse; silicone and glass tolerate boiling or dishwasher cycles for occasional deep sanitizing. Remove the airlock components and silicone seals before running through a dishwasher to preserve fit and longevity. Store parts dry and assembled loosely to prevent trapped moisture.

• Disassemble metal lids from silicone parts before deep cleaning.
• Sanitize glass weights and silicone in boiling water or dishwasher as needed.
• Rinse brine residue immediately to avoid staining or odors.
• Keep spare silicone rings and grommets in a dry container for replacement.

What practical tips help avoid common fermentation issues?

Minimize air exposure by ensuring the silicone ring seats evenly under each lid and the weight keeps ingredients below the brine. Use the silicone tong to lower weights slowly to avoid splashing and trap less oxygen. Check airlocks periodically—bubbling indicates active fermentation; replace the water in the airlock if it evaporates.

• Press ingredients firmly to release liquid and encourage submersion.
• Top up brine if liquid level drops during active fermentation.
• Use the included replacement grommets if seals wear or leak.
• After fermentation, swap the airlock for the silicone cap for airtight refrigeration.

Who is this for? This Artcome kit is ideal for home fermenters who want a compact, reusable solution for small-batch projects using wide-mouth mason jars. It suits beginners who appreciate simple setup and clear components, as well as experienced fermenters who want replacement parts and durable materials to maintain multiple active jars. Jars are not included, so buyers should have or purchase wide-mouth mason jars to complete their setup.
