Lasipurkit

Lasipurkit is a term used to describe glass jars commonly employed for food preservation and pantry storage in Nordic markets. The jars are typically transparent and come in a range of sizes, from small 100 milliliter containers to larger one-liter jars. They are designed to hold jams, pickles, sauces, spices, and dry goods, and are valued for their chemical stability and reusability.

Most Lasipurkit are made from soda-lime glass, with lids that may be metal screw bands and flat metal lids or plastic snap-on tops. Some variants use rubber or silicone gaskets to improve sealing. The bodies are often straight-sided for easy labeling and stacking, and the mouth diameter varies by size. Higher-end lines may use borosilicate glass for greater thermal resistance.

Historically, glass preserving jars gained widespread use in Europe during the late 19th and early 20th centuries, and the term Lasipurkit has become commonplace in Finnish and other Nordic markets to refer to this class of jars. Today, they are commonly sold through kitchenware retailers and are a staple of home canning, baking, and DIY storage.

In contemporary use, Lasipurkit support home canning and long-term storage, while also serving as containers for crafts, gifts, and organize small items in households. Proper use includes following safety guidelines for canning and storage and avoiding overheating sealed jars.
