AI Appraisal Estimate

This is a 1-litre capacity liquid measuring cup manufactured by Pyrex. The item is constructed from thick, transparent soda-lime glass, exhibiting a slightly bluish or greenish tint characteristic of modern Pyrex formulations. The cylindrical vessel features a rounded pouring spout and an integrated D-shaped glass handle. The exterior surface is prominently marked with heat-sealed red paint depicting measurements in metric units. The scale begins at 200 ml and extends to 1 litre, with numerical markers at 200 ml intervals (200, 400, 600, 800, 1000/1 litre) bracketed by horizontal line increments. The branding 'pyrex' appears in lowercase bold red lettering at the top. Condition-wise, the glass appears clear without major clouding (etching) from dishwasher use, and the red pigment is largely intact with minimal fading or scratching, indicating light to moderate use. There are no visible chips or deep cracks in the rim or base. Based on the lowercase 'pyrex' logo style, this item is a contemporary kitchen staple produced within the late 20th to early 21st century. The craftsmanship is utilitarian, designed for thermal shock resistance and durability in culinary environments.

Upon visual examination of this 1-litre Pyrex measuring cup, I have identified it as a contemporary utilitarian piece produced in the late 20th to early 21st century. The lowercase 'pyrex' branding and metric-only measurement scale indicate this is a modern iteration rather than the highly collectible vintage borosilicate 'PYREX' (uppercase) versions manufactured mid-century. The condition appears excellent; the red heat-sealed markings are vibrant and show no significant degradation or 'dishwasher haze,' which is the primary factor in maintaining the value of secondary-market glassware. Physically, the thick soda-lime glass shows no signs of chipping at the spout or stress fractures at the handle attachment point. Market demand for this specific model is driven by functionality rather than rarity. Because this item remains in active production and is widely available at retail outlets for approximately $12-$22 USD, the secondary market value is capped, typically realized at thrift or estate sales. The primary value-adds here are the lack of etching and the intact scale. However, image-based appraisal has limitations: I cannot verify the presence of micro-scratches or 'flea bites' that are only detectable by tactile inspection. A full authentication would require physical handling to check for surface tension and weight to confirm it is indeed Pyrex brand glass and not a generic imitation. No specific provenance is required for this class of kitchenware, though original retail packaging would slightly increase the upper-end valuation.
