I think you just need a couple more mortar and pestles... Then you have yourself a "real lab"

This is my workbench. On the left side I do the reactions. You can see my mobile stand on which I keep my mobile for recording videos to upload on
Youtube. On the right side I have my vaccum filtration setup and a Thieles tube setup for recording melting point of organic compounds that I make.

Have a small cute home chemistry lab.

Oh wow, I didn't even see the brass one, that's awesome! I count 15 (including the brass one), is that right?
I can hardly give you grief for having a crazy about of mortars and pestles. I myself have way too much glassware, some of which will probably never
get used for anything serious, lol.
But I really do like your lab. It has an artisanal feel to it. Reminds me of The Knick (amazing TV show).

Seeing the brass mortar and pestle reminded me I had an old tarnished one out in the garage. I tried some Bar Keepers Friend (Oxalic Acid) and then
some clear ammonia not having any brass cleaner. It used to reside on my fireplace. Interestingly, it makes a loud bell sound if tapped with the
pestle.

Apparently these other bronze looking things I have are mortars without a pestle. I saw the same design and concentric ring pattern (on the bottom of
them) as mine on eBay. Oddly my camera made them look more yellow like brass Maybe of interest ...

Over the last 4-5 months I've been converting my rather large cellar into a home lab, and by last weekend I had all the equipment and chemicals
necessary to run my first procedure. So I decided to make the first concentrated chemical I ever handled in a professional setting - nitric acid.
The experiment was a dry distillation using sodium nitrate and sodium bisulphate, the latter obtained from a pool chemical kit sold at my local
B&Q. The gas outlet from the receiver flask was run into a Drechsel bottle containing 10% w/w caustic soda, also from my local B&Q.
After turning on the heating mantle, nothing happened for a few minutes, but sure enough, after a few minutes, faint brown vapour appeared over the
reaction mixture, which soon filled the whole apparatus - the joints were sufficiently tight that very little vapour escaped, but I had a large
extractor fan set up just off-camera in case things got out of hand.
After about 40 minutes of heating, liquid started to condense in the receiver flask, and continued at a steady trickle for about an hour. Once it had
stopped, the heat was turned off and the apparatus was allowed to cool to room temperature. Since the liquid in the Drechsel bottle was starting to
suck back, the bottle was disconnected.
About halfway through the distillation, I replaced the cone adapter and thermometer with a closed well, as the thermometer was unreadable through the
misty condensate, and the plastic washer inside the adapter perished due to contact with nitric acid vapour. The Drechsel bottle was pretty useless,
as very little gas got that far through the apparatus, but the caustic soda solution was useful for neutralising the acid vapours at the end of the
procedure.
On releasing the receiving flask, acrid white fumes typical of concentrated nitric acid were evolved. The yellow liquid in the flask was very
carefully weighed out into an amber glass bottle, and its density was determined to be around 1.5 g/cm³, meaning it was close to 100% nitric acid -
somewhat stronger than I'd expected. Assuming a concentration of 100%, the yield was 25 grams, or about 70% with respect to sodium nitrate.
(I'd falsely assumed the sodium bisulphate was the hydrate. The fact it stayed solid well above 55 °C, the nominal melting point for the hydrate, was
the first clue it was anhydrous.)
To test the nature of the acid, a few drops of it were dripped onto a discarded pair of nitrile gloves - the drops burned holes in the material, and
produced smoke. A few drops were dripped onto a penny; corrosion occurred at the surface, along with the formation of blue copper nitrate and the
release of nitrogen dioxide.
All in all, a pretty successful first run.

I moved in 2016, so I got rid of all my chemicals (sold them in bulk to a member here).
When I retired in 2018, I started doing a bit of chemistry again. I am only doing chemistry very occasionally, but I still have managed to accumulate
a fair collection of chemicals again.
Most of vials with homemade labels are chemicals I made myself from other chemicals.
