  1. Old lab glassware

  4. I have some old lab glassware that I stumbled upon. It is probably 40 years old. Would this glass be okay to use? It doesn't seem to be very dirty. How do I clean something like this? Or should I get new stuff?

  60. Post pics. Usually glass is cleaned with acetone. You might need to invest in rubber stoppers if you don't have ground joints.

  77. glass is actually a fluid at room temperature. That is why you can see through it, the particles are just moving very slowly so it retains shape.
  78. Over time gravity will effect the structure of the glass usually weakening it, for example old windows are thinner at the top thicker at the bottom. The integrity of the glass could be compromised.
  80. Also regular lime glass is not meant to be heated in the same way borosillicate glass is.
