Here is a pair of mint master inks with great mold strikes. These are circa 1880s. One size appears to be a quart and the other a pint.

Both are debossed: VITREOUS STONE BOTTLES / J. BOURNE & SON / DENBY POTTERY / NEAR DENBY / P. & J. ARNOLD. / LONDON / ENGLAND

Height: 9 3/4 & 7 1/2" 
Color:beige

Condition: nearest mint - both are structurally perfect and clean. The smaller one has a few wear nips on the spout, but no harm.

Reference Number:  TR157
