The bowl and foot have numerous small bubbles and some impurities commensurate with date of manufacture. The bowl and foot have clear tooling marks. The pink tint no doubt results from the use of manganese in the flux but its use as a colouring agent would appear to be deliberate since the stem is of clear glass. For a similar type, see Bickerton p. 52, illustration 13.
