A white 18-toothed cog cane - with a red, blue & white cross - centres this well made 5-row concentric produced, most likely, in one of the - as yet - unidentified English glassworks. The canes in the first three rows are slightly flared. The white, pale-blue & mid-blue crimps all have a cross in the centre. The 4th row has plain white crimp canes whereas the outer row is composed of complex white canes sheathed in an unusual purple!
These canes have been drawn neatly into the slightly concave, polished base to a fairly large porthole at the unfinished pontil. Like a modern day Whitefriars weight, there is a distinct ridge between the set up and the encasing glass.
