Cesium's atomic number is 55 and its symbol is Cs. It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F), which makes it one of only five elemental metals that are liquid at or near room temperature. It ignites spontaneously in air, and reacts explosively with water even at low temperatures, more so than the other alkali metals. It even reacts with ice at temperatures as low as −116 °C (−177 °F).Because of the bright blue lines in its emission spectrum, its name was derived from the Latin word caesius, meaning sky-blue. To obtain the first pure sample of Cesium, 44,000 liters (9,700 imp gal; 12,000 US gal) of mineral water had to be evaporated to yield 240 kilograms (530 lb) of concentrated salt solution, which were required to start the purification process. This display is contained within crystal clear Lucite acrylic.

Safety

We get asked about the radioactivity and overall safety of the periodic tables/cubes from time to time. These are legitimate concerns and we wanted to address those concerns here. Although there are several elements in the cubes that are dangerous or toxic, the acrylic and glass ampules make the products safe to handle and store.

The average American is exposed to 0.034 mrem/hr from background radiation (300 mrem/year). In other words, a person will get three times the radiation from natural background radiation which includes the sun, food, radon, and the environment, than they will from holding a radioactive element in one of our Lucite Acrylic displays.

Care Instructions

Wash with mild soap or detergent and lukewarm water. Use a clean, soft cloth, or sponge. Rinse and blot dry with a damp cloth or chamois.

*Never use abrasive cleaners, household cleaners, window-cleaning fluids, scouring compounds, gritty cloths, or strong solvents such as alcohol, acetone, carbon tetrachloride, etc.*

To maintain the brilliant luster of acrylic, wax and occasionally with a quality grade of automobile paste wax (NOT A CLEANER WAX COMBINATION.) Apply a thin coat with a clean, cotton flannel cloth. Then wipe with a clean damp cloth. NEVER USE HOUSEHOLD SPRAY WAXES.

Proudly made in the U.S.A.

The Best Element By Far!

Ahh Cesium, a metal more expensive gram for gram than gold, I believe the only other pure metal to have a gold colour, but you really don’t want your ring made of it! Course if it was exposed to the air it would immediately blacken, melt and likely self ignite. This metal just doesn’t want to be!

Inside the cube it’s a brilliant sample, slightly more than I was expecting! It’s been artfully melted into one place in the argon filled tube, and it’s a beautiful, eye catching piece.

Course with a melting temp of 28.5°C, I could always stick it in the oven and try to crystallise it or move it around but for now, I love the look of it and it’s a brilliant addition to my collection.

Absolute Perfection

The craftmanship that went into this cube is incomprehensible. From the absolutely perfect glass ampule, to the cesium being heated up and cooled onto a specific spot of the glass to make it more visually pleasing. This is the best way to show this beautiful element naturally.

Honestly the best element here (10/5 stars)

Beautiful liquid gold. Beautiful element, and beautifully made. I stick it in a 37°C oven in my lab to melt it and I crystallize it. It’s gorgeous and entertaining, especially on late nights in the lab when you’re waiting for an experiment to finish before you can go home
