Oval Ceramic Slow Cooker Replacement Insert

This item is a heavy-duty, oval-shaped replacement stoneware insert for a slow cooker or Crock-Pot. The vessel is constructed from thick-walled ceramic with a deep, dark brown (often referred to as 'espresso' or 'black') high-gloss glaze on both the interior and exterior surfaces. It features a wide rim designed to rest on the heating element housing and integrated side handles for lifting. The underside reveals an unglazed, cream-colored bisqueware base which provides traction and heat distribution. This base area shows two distinct incised marks: a stylized, cursive 'M' and the number '4', likely representing mold numbers or factory production identifiers. The condition appears well-preserved with no visible cracks or deep chips, though there is minor shelf wear and dark scuffing on the unglazed bottom ring consistent with regular kitchen use. Based on the design and markings, this is a contemporary mass-produced kitchen component, likely late 20th or early 21st century. The craftsmanship is industrial-grade, prioritizing durability and heat retention over ornamental detail.
