is this known as Canary Flint? or is this just yellow uranium glass?
I've gone back to the MW site and found the comment re Canary Flint dating to around 1850-1870 which is where I remembered it from and the canary flint does seem to be more transparent and less intense than the honey pot glass.

It goes by BOTH names, depending on where you live and what time period you are talking about.  the true definition is the last one:  it is yellow and it is made from uranium salts. 

CANARY is a name invented by glassmakers to describe the color (instead of just calling it yellow).  Flint refers to the fact that the early stuff (prior to 1863 for the most part) had a lead content.  However, some manufacturers continued to use it, until the cost was too prohibitive and they either switched to another formula, continued to try to market the 'upscale' market, or they went out of business.  1863 is when the soda-lime formula was invented in the US (due to lead being used primarily for the American Civil war and the expense. 

The brightness or intensity has to do with the manufacturer, the formula used and a lot of other factors.

The really old lead uranium glass is a much more acid yellow and doesn't tend to have that green hint (not the colour of the glass itself but the "greenish aura" you get in daylight) and it weighs a ton compared with something similar in soda glass or even with a lower lead content
