This is a Fire King Vitrock Range Set series Red Flower grease jar. Unlike the main body made of milk glass, this is made of VITROCK glass, which has a ceramic-like texture, making it a very rare item. It does not have a lid. It is in very beautiful condition and shows no signs of use. There are no chips or cracks, but there is a slight scratch on the rim (please check the photos). Other than that, the inside is also very beautiful, and despite being vintage, it is in very mint condition. Markings: None Manufacturing period: 1940s-1950s SIZE: Diameter 8.5cm, Height 13cm Although it is in very good condition, there may be some scratches typical of antiques, as well as unevenness in the glass from the time of manufacture.
