Chemistry glassware test tubes

Set of glass accessories, chemistry equipment, which will bring back many school memories! It includes a stemmed glass, two test tubes of different sizes, a small round flask, called a “balloon”, and a stirrer (glass rod). This material is difficult to date because it is standard material which has been (and still is I imagine) used for many years in the school environment in particular, it should be noted that the glass is relatively thick, to be solid, unlike the tubes “modern” essays made for decoration only. The whole thing is in rather good condition, no cracks or chips, but does not hide some slight signs of use: small stains that I have not managed to clean (either because they are inaccessible to my basic cleaning tools or because they are indelible with my basic cleaner), such as, for example, opacity in the neck of the balloon, small spots at the bottom of the tubes or even opaque traces in the stem glass. The stemmed glass measures 13 cm in height, the test tubes measure 23 cm and 16 cm in height, the stirrer measures 25 cm in length and the flask measures 7 cm in height.
