Meerschaum is sepiolite, a hydrous magnesium silicate mineral clay. It withstands intense heat without scorching or burning through as briar does. However, high enough heat might crack it, so go easy if using a butane jet lighter that is not recommended for lighting pipes. Meerschaum is fragile in that it scratches and gets bruised a lot more readily than briar. Expect a meerschaum to crack if dropped on a hard surface. Waxing is usually unnecessary for meerschaum pipes less than 25 years old. However, if a century old meerschaum had been poorly maintained, a jojoba oil - white filtered beeswax coating after thorough cleaning will produce dramatic results as depicted here. However, the rate of color change slows after a certain point.

Each meerschaum colors differently. I have a Hayim Pinchas lion head that did not begin to truly color until I had been smoking it for 30+ years. A used Andreas Bauer didn't start coloring until I had it for five years, and for the past two years it has been coloring rapidly.
Wax a meerschaum sparingly. I saturated one pipe so much I was tasting burning beeswax for two years. Additionally, applying wax may actually bleach out the color that had previously been there. It may take several years of regular smoking before the color returns but when it does, it is usually deeper and more uniform.
