Back working in school science technician-ing. RSciTech. Background in coatings R&D. Loves Chemistry and makes pictures out of chemical droplets or from videos of chemical reactions (RGB plots). Custodian of the #GardenIndicators spreadsheet!
Blackberries! Loads of them! Going back tomorrow for more. Will make a crumble and jam. Have a plan for some colorimetry too😀#GardenIndicators

I’ve been testing out ‘things that glow’ for our chemistry club. A Horse chestnut branch in water just blew my mind! Thanks @andrestrujado.bsky.social for the suggestion ages ago. The others are pumpkin, sesame and fennel seeds in vodka!

Here’s the pH profile of a small purple viola petal used as a cake decoration. I resisted the temptation to eat it, instead it gave itself to science! #GardenIndicators

I had to buy some flowers for a practical at work, naturally I chose the ones I thought would give an interesting pH profile. Nice colour with Al ³⁺ ions too! #sciencetechnician

Roses are red, violets are blue….pink, turquoise, green and yellow!

A Christmas tradition and the 3rd #GardenIndicators Christmas edition - Red Cabbage! Such a wonderful range of colours at different pH. Merry Christmas everyone 🎄

The second #GardenIndicators Christmas edition shows the pH profile of poinsettia bracts. Just look at the cheeky pink and purple in the RGB plot!

#GardenIndicators Christmas edition! I bought the cranberries purely for the science and now I’ve got to make cranberry sauce from scratch! Here’s their pH profile and the RGB plot of the acidified extract neutralised with 0.1M NaOH, then adding 2M NaOH

The Science Techs decorated the science department and we won the school Xmas decorations competition. Great team effort. Nice to show off what we do! Snowflakes, chemistrees, stick insects, and physics interactive light generators!

Flower extracts store really nicely in the freezer, this one is from May. It shows the pH profile of a deep purple Aquilegia from pH1 to 13 #GardenIndicators

Here’s a 3,5-dinitrophenol snowflake designed by our Head of Chemistry! ❄️

Here’s the pH evaluation of a red sweet pea from my garden. A cheeky blue around pH 8-10 is always a bonus! #GardenIndicators

Doing a bit of prep today for our Christmas decorations with some laboratory snowflakes based on Volumetric flasks, Bunsen burners, Pear-shaped flasks and Separating funnels!

Post a picture you took (no description) to bring some zen to the timeline

Here’s the pH evaluation of a pink & white geranium from pH 1 to 13. The bottom image shows an RGB reaction plot, using actual RGB values to produce an image of the dynamic neutralisation reaction. Lovely purple with Al³⁺ ions too💜#GardenIndicators
