💎📦 The @USCrystalComp crew is at it again!

This time at @UCFChemistry , where Fernando @fjuriberomo and grad student Abdullah have been busy packing alum for our #2026USCGC crystal growers! 🧪

It takes a village to grow a crystal… and apparently a LOT of packing tape! 😂

[US Crystal Comp @USCrystalComp]

❤️💎 Friday night DATE NIGHT, USCGC style!! 😂

Nothing says romance quite like 5 kg of alum and a roll of packing tape!📦🧪

Tasha (my wife and fellow crystallite!) and I spent our evening packing #2026USCGC orders @UBChemistry.

Some of you are SERIOUS about growing crystals!💎

That's a wrap on our Crystal Club at the Colchester Middle School. We harvested our crystals yesterday for #2024USCGC. The crystals came out great and the students grew our biggest yet, 60g! Many thanks to Jessica Frank for organizing the after school club with @KarenGlassLab.
