Doulton Slater's Jardiniere - Doulton & Slater’s Patent refers to a distinctive late 19th-century pottery technique (c. 1885–1930s) where actual lace was impressed into wet clay to create intricate, textured patterns. Developed by John Slater, the Artistic Director at Doulton’s Burslem factory from 1887-1914, this method often featured hand-painted floral designs on a muted ground, frequently highlighted with gold gilding.
