For those who have forgotten why mineral oil is used with light microscopes:  8)
Immersion Oil


These lenses are designed to be used with cedar wood oil, a naturally occurring product from the tree. Its refractive index of approximately 1.52, is almost identical to that of the glass used for slides and coverslips. Synthetic oils have been formulated which are more stable, and can be obtained in various viscosities. Other fluids such as glycerine, and also mineral and vegetable oils work , but their refractive indices and dispersive powers vary somewhat from that of glass, and hence cannot be expected to elicit the best imagery from the specimen.

Agelbert NOTE: BUT, Mineral oil CAN replace GLASS as a cheap, plentiful, ubiquitous, never gonna run out, etc. lense material.  ;D




Rob not the poor, because he is poor: neither oppress the afflicted in the gate:
For the Lord will plead their cause, and spoil the soul of those that spoiled them. Pr. 22:22-23
