I found a unique lampworking workshop where I learned how to make mung bean sprouts when visiting family in Taiwan last month. These are not skilled glasswork, but I have made my first models of economic botany of some sort! With a bonus clear sprout for further experimentation with glass painting.
Photo of the author pulling a cane from a white glass rod in front of a torch. Photo of five pieces of mung bean sprouts made of glass. One is in clear glass, two have translucent white stems and light yellow embryos, and two have translucent white stems and green embryos.

Back to the #MuseumBoerhaave to work with two rare compound microscopes from the 17th-c., one made by Giuseppe Campani and another attributed to John Marshall as the maker. So many new thoughts emerged from observing how colors and form changed under the lenses. #VisualizingTheUnknown #histsci
Photo with a microscope attributed to John Marshall as the maker in the front and a microscope made by Giuseppe Campani in the back. A tiny slice of a dandelion stem under on a petri dish under the lens. Magnified view of the dandelion stem slice when it was hydrated, showing vibrant greens in coloration. Magnified view of the dandelion stem slice when it was almost dried, becoming more shriveled in form and brown in coloration.

Last highlight was a lunch talk at the uni. Herbaria to share my current research. So happy to see many interested people; the room was pretty packed. Got a bonus tour to more items at the Herbaria afterwards, including some stunning wax fruit from early 20th-c Japan from economic botany collection!

Another major event was studying the famous Blaschka glass flowers on site. It was amazing to examine these incredible models in person, together with the collection manager & conservator. I also got to spend some time in the archive consulting some historical documents on the glass flowers.

Students then tried their hands at woodcutting in the 16th-c. manner. Several students liked the technique so much that they returned for more woodcutting the following week during their free experiment times!
Work stations for sixteenth-century woodcutting experiments. 22 inked woodblocks carrying various letters from the alphabet and other images.

I visited Harvard Uni. the past two weeks. A major event was giving a workshop for the Summer Institute for Technical Studies in Art @ Art Museums. For the theme Experiment, I showed how I incorporate historical reconstruction/hands-on research in my past/present projects & the related experiments.

Banner image for the Plant Humanities KNAW-Huc, featuring an orange daylily in front of a green background. Poster for the Plant Humanities KNAW-HuC. Description on the poster: Plant Humanities has emerged as a convergence point for multiple disciplines interested in the connections between plants and people. Such convergence has the potential to address important questions of today, such as climate change, biodiversity decline, and decolonization of knowledge. This colloquium brings together researchers in Plant Humanities in the Netherlands to showcase the many ways in which people have related to plants in the past and present. Program: 10:15–10:30, Check-in and Coffee; 10:30–11:00, Welcome and Short Introduction; 11:00–11:30, Becoming Global?

Took students of NIKI/Huygens course "From Leonardo to Steno" to the Opificio delle Pietre Dure last Friday. Excellent collection for discussing early modern art, science, & material practices and for exercising looking closely by drawing textures. We were amazed by the incredible stone paintings!
Photo of a stone painting featuring a bouquet in a vase in the center, surrounded by a border with a geometric pattern. Photo of a section of the museum, showing historical workstations for cutting, grinding, and polishing stones, with a wall-to-wall display of different kinds of precious stones used for pietre dure in the background. Photo of a display case that shows the different stages of making a pietra dure, including the initial watercolor, model drawing for transfer, small sections of stones that are joined to create part of the image, and different kinds of stones as the color palette. Photo of a piece of the Terra del Paese di Rimaggio, or Marna (Paesina).

Another article I'm working on within the #VisualizingTheUnknown project is about historical three-dimensional representations of plant anatomy. What a treat to be able to see these incredible 18th- and 19th-c. wax botanical models at #LaSpecola in Florence. #histsci
Photo of many wax botanical models in pots on display. The models are in life-size to the modeled plants. The walls and display shelves are painted in green. Photo showing the wax botanical model of "Cactus truncastus" in front of a green wall. The plant is placed in a pot with an oval cartouche that shows the name of the plant, as known in the eighteenth century. Next to the pot (to the bottom right of the picture plane) is a small wax model showing the flower head that is cut in half and placed on a ceramic dish shaped like a seashell. Photo of wax models of plant anatomy displayed on shelves. The walls have pink wallpaper and the shelves are also painted pink. Photo of a set of wax models showing the physiological preparation of Cucurbita pepo under a glass case.

Test run of working w/ #EarlyModern #microscopes at the Museum Boerhaave for a new article I'm starting! A big part of #visualizingtheunknown is to better understand what early microscopists saw & the encountered challenges by redoing their observations. Back for more observations soon. #histsci

I talked about some of the stunning botanical books in the Teylers collections on day 2 of VisionLab! We focused on the various book formats and how the physical sizes of the picture planes affected the depictions of plants & microscopic observations. #VisualizingtheUnknown
Hand-colored engraving of a crown imperial flower and bulb from Basilius Besler's Hortus Eystettensis (1613). Tab. 56 that depicts the backside of the Theca, the belly of the Theca, the column of the magnifid, flower of Hyoscyanus, one of the spermatick Thecae, the edges of the Theca open, and the column in the middle of the flower. From Nehemiah Grew's The anatomy of plants (1682). Hand-colored etching of various parts of wheat in the Blackwellianum Herbarium (1750-1773).

Jumping right into action with day 1 of VisionLab, in which we looked at books on butterflies & moths at the Teylers Museum, Haarlem. Discussions centered around how to visualize microscopic observations of the insects through prints and related challenges. #VisualizingtheUnknown

Herbarium? is a project I recently completed. The idea and material collecting process started in 2022 when I was looking into early modern pressed plants as a small part of my PhD research. You can now see the creative project through the link:

Practicing for upcoming collab w/ bookbinder/toolmaker Brien Beidler on a woodcutting experimentation we've had in mind since few years ago. It'll still take some time, but the wheels are turning! Image is a decoration from the Nederlantze Hesperides (1676) at a reduced size.

Branching into toolmaking! Had the pleasure to follow part of the workshop by the skillful&talented Brien Beidler at the Fopma Wier, Leeuwarden. My first homemade finishing tool for leather stamping/bookbinding features a simple flower. Now I should actually get into bookbinding.

Teamed up with Henrike Scholten from Durare Project to find some handmade papers with different properties. The paper mill De Middelste Molen in Loenen offers factory tours and many paper options. Always a delight to pull a sheet of paper from the vat!

As I most likely won't have this level of creative freedom for the eventual monograph, I put more thought into designing this version, thanks to the minimum requirement for formatting for Dutch dissertations. Commission possible if this kind of design is appealing! 2/2
