Curated turns us onto this Studio Glithero piece:
“The result of a process which captures direct impressions of botanical specimens, London’s Studio Glitero have created a trio of objects. On the process they note, “Using age-old preserving techniques, humble weeds of inner London borough pavements are pressed, dried and then composed between plates of glass that function like photographic negatives. Working with light sensitive chemicals, the plates and tiles are then exposed under ultra violet light, which develops a photogram of the specimens in intense Prussian blue. What remains is a crisp white silhouette of the specimens, creating intricate floral designs of the subjects from root to tip. ” With this complete, the group produces vases, lamp shades, and glorious tiles.”
