sorry, can't help with attributions for either, but the following comments will be of use to members trying to provide answers - also best to post one piece of glass per post - helps to avoid confusion
It will help if you can post pix which will enlarge when clicked - this will assist with trying to determine which patterns you have, and always helpful to give dimensions.
The biscuit barrel looks grey due to the presence of lead oxide - added to improve the light refracting properties in cut glass, and to produce a less hard material that is easier to cut - in the U.K. the minimum lead content should be 24% but may be as hight as 33%. Look carefully for a backstamp (makers name) on the underside - can be very difficult to see, sometimes - pieces can be attributed to a particular cut pattern, if you know which factory to start with. If the factory remains unknown then provenance relies on recognition from catalogues, usually, or someone's memory. Lead crystal will sometimes ring if struck (gently) - although this doesn't guarantee it's lead, apparently.
With regard to the pressed bowl, you might try Pamela's site ... http.www.pressglas.pavillon.de - awlays a good start with pressed material.
A yellow tint is often an indication of the absence of lead, which is what you'd expect, generally, with pressed glass.
