Formose reaction - how to reproduce?
There's one amazing reaction - conversion of formaldehyde to some sugars by adding calcium hydroxide. How hard is it to reproduce?

It's extremely easy to reproduce. First I though I could make methanol from formaldehyde via Canizzaro, but instead I've got the formose as only
product. Though, I was using sodium hydroxide, but calcium hydroxide is a strong alkali too.

What amounts of chemicals should be used for the experiment?
Does it react far enough to eliminate the smell of formaldehyde?
How much ventilation is needed? Is open air enough or fume hood is needed?
Can the reaction be done in enclosed container without risk of explosion?

I doubt that every proportion of formaldehyde and alkali works equally. I doubt that the concentration of formaldehyde solution doesn't matter. I
assume there are some optimal ratios of chemicals (formaldehyde, alkali, water). But I couldn't find them anywhere.

Do you have any practical experience with reproducing this reaction? Thank you.

Isn't there a book about formol in the Library section?
