Re: GLUEING WAX
Some biologists are forever making thin sections of things to be stained and examined with a microscope. The preserved specimen is infiltrated with molten wax, cast in a mold and cooled. The "block" has to be attached to a support to ride up and down for the section cutting process. These blocks are sugar-cube size or a bit bigger.
For attachment, a thin flat metal blade is heated with a simple alcohol lamp.
The blade then rests on the support, the block is set on top and the hot blade melts the wax at the interface. Pull the blade out, let it cool = stuck on but good.
A table knife would do just fine, straight or bent.
