Canada 24 & 25. Question About Watermarks, Laid Paper Etc.

Hi there! I am new here but have been on CCF for quite some time. I have been going through some old stamps and I am having difficulty on a few.

These two stamps are described in the collection as being watermarked, though I do not see any watermark like the crown you see on British stamps. All I see is a regular grid. I am not sure though if this grid is "woven" or "laid". The photos that I can find on line are ambiguous. In the case of the 3 cent, the paper is clearly different and thicker than some other that I have. Are they thin paper? Is something here watermarked? Laid paper? Any comments or thoughts most welcome.

Some different #25

First, have you used watermark fluid or Ronsonol to examine these? Because we won't be able to see anything by looking at the dry backs.

There are two possibilities for watermarks.

See posts on this page by Coriandre and gportch. A stitch watermark is an artifact from the papermaking process looking somewhat like a tire tread mark.

The other is a papermaker's watermark, outlined letters reading "E&G BOTHWELL / CLUTHA MILLS" of which only a part of some letters will normally show up. Example shown here:

A search on "laid paper" on SCF gives this thread:

The 3rd post shows what laid paper looks like in watermark fluid. It also shows wove paper in watermark fluid. Is that the grid you are talking about?

Nothing looks like thin paper here, which is also very porous, evident in watermark fluid.

I recommend you buy a Unitrade Canada catalog, new or used.

First two are definitely wove paper.

The scan of 3 is too poor to comment

Thanks for the tips. Obviously lots to learn and study if I am going to get back into stamps!

Very informative post Hy-Brasil. And thanks for the topic smallcentguy. Exactly what I was looking for.

I picked up an album recently with classic U.S./Canada issues. The album was intricately customized with conditionally exceptional pieces, but then with some pretty junky looking pieces.

I thought there may have been a reason the collector added these into the album, and sure enough found that the 24 is the Bothwell watermark with diamond stitch paper:





This picture is not in WM fluid, but when it is the bottom appears to show the the topmost letters of BOT in reverse (I believe).
It's rather easy to see even without fluid because the stamp looks permanently wet

I wanted to ask about the 2 and 5c smalls in here as well, as they seem to be unique from each other in some way. Could you all take a look?

1st: Looks like horizontally ribbed paper





2nd: Looks rather normal




3rd: Pink paper

And now for the 5c's

1st: Has numerous indentions on the back




2nd: Looks normal




3rd: Has 4 circular indentions seen throughout (one underneath the hinge)




4th: Looks to be on the same diamond stitch WM paper as the 24
