Baker (Sunderland Pottery, 1984) lists the Sunderland or Garrison Pottery partnerships as follows:

1807 to 1812, John Phillips
1813 to 1819, Phillips & Co and/or Dixon & Co
1820 to 1826, Dixon, Austin & Co
1827 to c1834–39, Dixon, Austin, Phillips & Co
c1834–39 to 1865, Dixon, Phillips & Co

The earliest identifiable plaques belong to the 1820–1826, Dixon, Austin & Co period.  My research suggests that the Dixon, Phillips & Co impressed mark, surrounding anchor, might have been used between c1834 to 1850.

The first two plaques are circa 172 mm in diameter. The next six plaques are circa 177 mm in diameter. The last plaque is larger. Except for the last three plaques, all are stamped 'Dixon, Austin, & Co'.  The impressed marks shown, are from the plaques to their left. The right plaque on the third row has a transfer of a man and a woman dancing in front of a church. The initials 'I E A' are hand painted.

The Dixon, Austin & Co partnership ran between 1820–1826. After that the firm became Dixon, Austin, Phillips & Co (1827–c1834). It is possible that unmarked plaques of this type were made by the later partnership.

The first two plaques are 167 mm diameter, so 1 cm smaller than their black and yellow counterparts above. The third plaque is 173 mm diameter and the fourth is 175 mm. The last three plaques are larger (the last two are 182 mm diameter). The borders and hand-painted text of the third and fourth plaques, are matt over-glaze brown.  The left plaque on the second row has the impressed mark 'Dixon, Austin, & Co'. 

The first plaque is 176 mm x 140 mm. The circular plaque is 182 mm diameter. The second rectangular plaque is  188 mm x 150 mm. Rectangular versions exist with the 'Dixon, Phillips & Co' impressed mark, which was used c1834–1865. However, the only one I've seen had a faint and degraded transfer, which suggests it was made late in the life of the transfer plate. Therefore, it is possible that the plaques above were made by one of the earlier Dixon partnerships.

The 'Dixon' Wesley (above left) is easily distinguishable from the other Wesley transfers based on the Edridge portrait.  Unlike the portrait, the Wesleys on plaques tend to be surrounded by an 'aura' – a kind of divine force field radiating out from Wesley in prongs. The defining feature of the Dixon transfer (above left) is that to the right of Wesley there are 6 prongs, whereas on other Wesley transfers there are only 5 prongs, e.g. the Scott transfer (above right). The Dixon transfer, unlike the others, has a full stop after the word 'Society'.

The circular plaques are between 179 mm (centre left) and 184 mm (top right) diameter.  The first rectangular plaque is 180 mm x 142 mm. The second is 176 mm x 140 mm. The third is 188 mm x 150 mm. Though none of the above is marked, they have exactly the same Wesley transfer as pink-bordered plaques marked 'Dixon, Phillips & Co' and 'Dixon Co'. The moulds, decoration and colour palette of the first two rows of these plaques are identical to the 'Prepare to Meet Thy God' plaques above. The hand-written text on the circular Wesley plaques appears on earlier Dixon 'Prepare' plaques (see above). The banner 'THOU GOD SEEST ME' is, as far as I know, unique to Dixon, and appears on pink lustre plaques with Dixon impressed marks.

The plate below (192 mm diameter) has the impressed mark 'Dixon, Austin, & Co', used between 1820–1826. It confirms that the Wesley transfer was used alone, before being paired with Clarke in 1832, to commemorate Clarke's death. 

The 'Dixon' Clarke transfer (above left) has a curvy undulating 'aura'. Its peaks (or prongs to use the term in the Wesley section above) cling much closer to Clarke's outline, particularly at the bottom right, where the first is almost lost in Clarke's jacket. The above right non-Dixon (Scott) version has a similar curvy aura, but the peaks are much higher to the right of Clarke, particularly at the bottom. The white spaces between the peaks are thinner.

The first rectangular plaque is 180 mm x 142 mm. The second is 176 mm x 140 mm. The third is 187 mm x 148 mm. The circular plaques are circa 182 mm diameter. Though none of the above is marked, they have exactly the same Clarke transfer as pink-bordered plaques marked 'Dixon, Phillips & Co' and 'Dixon Co'.  The moulds, decoration and colour palette are identical to the three 'Prepare to Meet Thy God' plaques above. The banner 'THOU GOD SEEST ME' is, as far as I know, unique to Dixon, and appears on pink lustre plaques with Dixon impressed marks. 

These plaques were made post 1832 to commemorate Clarke's death.

The two rectangular plaques are 180 mm x 143 mm. The circular plaques is 183 mm diameter. Though unmarked, the plaques above share the same transfers as pink-lustre plaques with 'Dixon, Phillips & Co' and 'Dixon Co' impressed marks.  Click on the Prepare to meet thy god and Thou god seest me pages for more detail.

The two plaques above are 182 mm diameter. Though unmarked, the plaques above share the same transfers as pink-lustre plaques with 'Dixon, Phillips & Co' and 'Dixon Co' impressed marks.  Click on the Other scripture verses page for more information.

The rectangular plaques are 180 mm x 143 mm. Transcriptions of the verses can be found on the Poetic verses page.

The circular plaque is 181 mm diameter. The right rectangular plaque is 187 mm x 149 mm. These three plaques share the same Tee Total Society transfer.  Click here to read more.
