The foreshore was covered in silt. I considered climbing over the gate outside the National Theatre but the steps looked slippery so I continued to Gabriel’s Wharf and down to Ernie’s Beach. Even there it was muddy so I walked along the sand in the other direction before heading down underneath the wooden structure and then close to the river. I guess the boats hadn't started running until after the tide had gone out a way and so the silt hadn't been washed away.
It was cold that morning, winter really feeling like it had arrived already, and it was only about 4 degrees when I left my house.
Some finds:
A few pottery sherds from Express Dairies (the one saying EDCL and the one with the blue aster flower), perhaps from an Express Dairies cafe. I found there was a cafe at 102 Waterloo Road which was apparently a popular meeting place for gay men in the 1920s.

A tiger's eye bead. So pretty!
–
A pipe made by E. Spaull. The address on it is 67 Grange Walk, Bermondsey, which shows it was made between 1907 and 1942 by Mrs Elizabeth Spaull & Co. 
E. Spaull made clay pipes from 1880 to 1942 and was one of the last companies still making clay pipes in the twentieth century.
Apparently there is still a sign for the company at 67 Grange Walk in Bermondsey, so I will go and look for it sometime!
–
A piece of glass from an A.1. Sauce bottle. 
A.1. Sauce is a type of brown sauce and was likely manufactured in Vauxhall.
Apparently it was still being produced in England in 2020 for export to Asia, so might still be. There are also versions of A.1. Sauce available in the US and Canada.
The bottle would have looked originally like this one:

A piece of glass that says “Pimlico”. I've identified this as part of a bottle made by the Clayton Brothers. They were based in Pimlico. The bottle may have contained lemonade and was probably similar to this one at the London Museum:

Another piece of uranium glass, but not glowing as much, so perhaps it just has a uranium glaze.
–
A piece of a torpedo bottle, with the distinctive shape.
--
A sherd that says “Skey Tamworth.” This would have been from the Wilnecote Works which were founded in 1860 by George Skey & Co. The colour of the sherd makes it look like it could have been from a stoneware flagon.
–
The glass remains of what looks like it could have been a sugar or salt shaker.
–
I haven't been able to identify:
The sherd that says “101 Lea” - Leather Lane? Leadenhall Street?
The sherd that looks like it says “CEN”
The sherd that looks like it might have said “Cotton” - perhaps some kind of pot from a chemist?
A piece of glass that says “tary” on it.

A person with a bicycle appeared, also mudlarking, and then two litter pickers and a dog.
I didn't stay too long as I was getting too cold and there was a Tube Walk later in the day, but I found some interesting things.


(You need a permit to search or mudlark on the Thames foreshore.)
