As usual the obvious candidates without a shred of knowledge of chemistry told you all that I didn't know what I was talking about when I said that Silca was making a block that looked like Chocolate that converted grease to wax.

I do recall you mentioning something about Silca.  It would have been
nice if you had included your source of (mis)information.

The process is called "oleogelation".  It's mostly used for converting
unhealthy saturated fats into somewhat less healthy unsaturated fats:

Beyond what I've just read about the topic, I know nothing. Therefore,
you are welcome to speculate whether bicycles are faster with either
type of fat.

Grease and wax asr ONE chemical chain from being the same thing.

Ummmm... no.  They're close, but not that close:

"Most basically, oils and fats are triglycerides; fatty acid esters of
glycerine, oils being liquid at room temperature and fats being solid.
Waxes are esters of a fatty acid and a fatty alcohol. I am
deliberately not including substances of mineral origin."

"Oils are liquid at room temperature, fat is solid at room

Where the hell do you get Candle Wax from - TALLOW - which is animal
fat.

Ummm... you could make candles from tallow, but today's candles are
made from paraffin wax and stearic acid.
<https://en.wikipedia.org/wiki/Candle>
If you've ever smelled a burning tallow candle, you'll understand why
organic chemists were searching for alternatives.  Some of the
alternatives candle wax compounds were equally disgusting:
"Unravelling the Science of Candle Odours: Tallow Candles"

Votive or prayer candles were frequently doped with more pleasant
smelling aromatic perfumes to hide the tallow stench.

The lubricating grease on a new chain (SRAM no longer put this
grease on a chain) is petroleum based but the chemistry is the same.

 
Some years back there was considerable talk about heating chain lube
so it flowed into the chain better and I made a wax heater from a
electric cooking pot and used it for years. No thermostat so I
eyeballed it but it did seem to lengthen chain life considerably.

Goodness, now our resident BIPOS is telling us they heating oil is

Why not? You told us how important being a crew chief of an obsolete, never used bomber was important.

Never used bomber??? Yes,, never used to drop bombs but used  as a
reconnaissance aircraft by the 6091st Reconnaissance Squadron from
1954 till 1961.
