Most books and the know-how on practising Microscopy at more involved levels than just looking at things, either quickly prepared or made professionally, sadly lay in the past. Most books for sale no-longer discuss slide making, for example. Many of the chemicals that were commonly used, and easily obtainable, 20 years go are now treated over-cautiously and are deemed (almost in some kind of frenzied attempt to remove real chemistry from ordinary
human's grasp) as toxic!
Although not a complete solution, slides of a semi-permanent nature can still be made through the use of carefully selected and tested safe, easy to obtain, ingredients. It is not a pursuit a very young person can accomplish but certainly a 10 or an 11 year old with a bright intelligent mind could have a go at it.
Our site publishes many articles like this one by Walter Dioni but we also published a book of his work which is helping to bring back know-how on how to make specimen slides for hobbyists.
At the time of writing, no other book really captures the tested and proven methods that Walter pioneered.
