Deep Joy
Oh the joy of opening today's parcels 
A 250ml retort and a set of evaporating dishes.
The retort fits nicely with the brass mortar that came from a boot sale.
Let the Alchemy commence !

This image popped into my head
the eagerness is due to the delay between small scale batches,
based on your tag line,
maybe you should have got one of these instead

That woodcut print shows a retort of the same size - the man is just very very small (a hormunculus no doubt) 
Happy days with evaporating dishes !
Here's some calcium chloride solution getting boiled to bits as i type:
Dunno why i never bought an evap dish before.
It was a video by Akhil Jain that prompted me to get some - always boiled stuff in beakers up till now.

In Alchemy-speak :
Strange - i could preview that as straight text, and it worked, then gave an error when i tried posting.

How to tell if all the water that can evaporate has gone ?
Stick a watch glass over it - turn it over (and burn your fingers) if you see droplets.
Simples.
Amazed at how satisfying a small porcelain bowl can be.

Heating a small sample in a test-tube does the same thing, much more quickly. Same principle, though.

The idea is to get the water Out, not see if there is any water present, which the test tube idea would show.
I got half a litre of aqueous liquid to boil down to a solid !

Nope : it's a Scale thing.
Heating a small sample in a test tube will show if there is water, as you rightly stated.
It will not remove the water from a whole pile of stuff.
The simple maths here is the small size of the test tube compared to half a litre of dissolved calcium chloride.
Edit:
Product-esque:
likely .2 H2O at least, but happiness abounds !

Well, if I can't explain to you the error of your linguistics, I can't explain anything to you.
Mind you, you are the same one who told me that heating the bejeesus out of a CaCl2 solution was NOT the way to go:

As i recall, heating the bejeesus out of it IS the way to go.
Someone commented, from their Actual Experience, that they routinely heated it to above Melting Point to ensure there was no water.
Unlikely i'll ever need CaCl2 THAT dry, for the forseeable future.
Anyone who never does anything at all (apart from comment on the actions of other people on websites) clearly will not need to go to that extreme
either.

Hey aga, have you given that retort a go yet? Do you have any specific plans for it?

I liked it so much i started the next batch.
Solid now, yet still stinks of SO2, but that will go away soon.
Simple Pleasures are probably the Best.

Not messed with it yet.
I have in mind a whole Alchemichal world of ideas for it.
Edit:
Basically a bunch of Alchemy, which is where Chemistry began.
The majority of Alchemy was discarded when some parts of it were found to be profitable.
That fraction of Alchemy we now call Chemistry.
There remains a lot more unexplored territory.

The majority of alchemy was discarded when it was found to not work, just like astrology and other superstitions.
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.

So much is lost when one imagines one knows it all.
Science still fails to bridge the gap between the Macro and the Micro.
Sadly the most prominent proponent of that challenge died recently.
If it is old bollocks or new bollocks, no matter - take from it what is of use.

Aga, you do know that posting on sciencemadness is not the same as doing chemistry, right?
No???
I didn't think so.

I appologise for posting photos of the stupid things i have done, many many times over.
The Science i have done was, well, worthless, compared to your frenzied typing.
If, God Willing, i can some day refrain from pointless Actual Work, i can become more like you.
If not, i may as well commit suicide, as just Doing Things and producing evidence of what i did isn't as real as just typing words into a computer,
it's just some kind of happy food dance or some other weird spatial effect brought on by booze.
Thaks for the wake-up-call : obviously i need to stop Doing Anything and start focussing on virtual chat.
NOT.
Edit:
More calcium chloride boils away merrily.
No way any cock, none at all, can spoil today's Deep Joy
Ebay rarely delivers this large.

I find it funny that a retort is about the only piece of glassware you can buy on the Aldrich site without an institutional account.

Like you aga I got a nice boost to the lab in the form of an old corning stirrer! but the real big bonus is it can be easily modded to hot plate and
stirrer and more joy yet was got it for the same price as a new cheap Chinese stirrer!
Now if those damned stir bars would hurry up!
Is the retort fused quartz or standard boro?

Aga,
The photo you posted at the beginning is wonderful. The lighting and shadows are terrific. It looks like something that would have been on the cover
of an Aldrich catalog.
I nominate your photo to be on the start page of ScienceMadness.

That would be a wonderful idea, I love that picture. It’s like it’s bridging the gap between the old and new - modern technological spins on
antiquated equipment, with the simple and clean look overall.
In chemistry, sometimes the solution is the problem.
It’s been a while, but I’m not dead! Updated 7/1/2020. Shout out to Aga, we got along well.
