Gallium Element Cube

Gallium's atomic number is 31 and its symbol is Ga. Gallium has a melting point of 29.76 °C or 85.57 °F. This means that under the right circumstances you could melt the metal within this display cube and watch it slosh around within the cube. Because of its low melting point, it is used as an environmentally friendly alternative to mercury in thermometers. Gallium is also used to make metals with low melting points that can be used as a semiconductor.

Gallium attacks most other metals by diffusing into the grain of the metal and spreading throughout the entire piece making it extremely brittle. This is why Gallium is not allowed in carry-on bags on a plane. If some of the liquid gallium made its way to the plane's metal structure, it would make a large portion extremely fragile.

The gallium in this display is held within a glass ampule to prevent it from seeping into the acrylic during the hot casting process. This makes for an interesting mirror-like ampule that looks fantastic.

Safety

We get asked about the radioactivity and overall safety of the periodic table from time to time. These are legitimate concerns and we wanted to address those concerns here. Although several elements in the periodic table are dangerous or toxic, the acrylic and glass ampules make the collection safe to handle and store. The radiation from the uranium and thorium samples is extremely low. Autunite (uranium ore sample) has a radioactivity level of 0.01 mRem for a 2mm piece held in your hand for an hour.

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 the periodic table all day.

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.

My sons favorite element!

We’ve been watching the ‘engineered labs periodic table song’ & some fun with gallium videos. My son was so excited to get this! He was already trying to hold the cube under the covers to get it to melt! I told him on a warm day we’ll just take it outside :-) these items expand growing minds and look gorgeous!!! Ps. Upload more on YouTube so I can get my kids into more elements (and buy more)!!! Thank you!!!!
