We have six plates from the "Everyday" service of the Alexander Palace in the Nicholas II period. Here is a photo of a similar one.
Alexandra Feodorovna had a more ornate service as well, known today as the "Purple Service", however it was almost never used.
Here is an example of the glassware used. Simple Imperial Cypher design:
and another, more ornate:
an example of one of the napkins used daily (we have seen dozens of these)
The flatware we have seen was made by Ovchinnikov under Imperial Warrant. The everyday flatware was very simple, adorned only with the Imperial cypher of Nicholas II, engraved. Here is a photo of what the flatware looked like, although not with the Nicholas II cypher, otherwise exactly the same.
There were specific rooms in the basement for porcelain, glassware and silver (meticulously counted and recorded by the way!). Dishes were supplied by the Imperial Porcelain Factory. Anytime one was chipped or broken, yes the pieces were destroyed and replacement pieces were constantly made in anticipation of the need. Silver was from a number of suppliers, as Palace needs could sometimes be too much for one company at the time needed. Most silver came from Ovchinnikov, or Faberge. There was a specific service for specific uses. The one shown would have been everyday for just the family and regular Court visitors. There would be more and more ornate services for events such as special guests, or Gala dinners or State dinners. Glassware came from the Imperial Glass Factory, again as needed but replacement pieces were always on hand to meet demand to replace broken ones. Typical service sizes would be enough for 250-500 persons, at four forks, four knives, four spoons, small zakuski plates, salad plates, side plates, dinner plates, dessert plates, tea, coffee service plus serving pieces, and water, red wine, white wine, champagne and cordial glasses. So, yes there were vast amounts of the stuff, which accounts for the fact that it isn't so impossible to find the china, glass or napkins. The silver, of course, was confiscated by the Bolsheviks and mostly melted down, with only a very few and now rare examples, sold to foreigners at Antikvariat. The only silver flatware we have seen personally was that taken out by Empress Marie Feodorovna and GD Xenia when the left Yalta. Other members here will have more details I'm sure.
