How is a "crystal" vase different from a regular glass in how it's made? The only method I know of to make a glass is glass blowing. How do they make sets of glasses all exactly the same size and shape?

Some crystal is made by hand, but not all of it is. If you examine some pieces of the same type of glassware, for example, you may or may not see slight differences (particularly if a piece has cuts in the crystal). Hand-cutting means that each piece has had a pattern traced on it, and then the piece is cut with a stone wheel. This allows for slight variances in the depth of the cut, the angle, length, etc. Companies such as Waterford and Kinsale use this method, with the molten crystal gob first blown by mouth to the desired shape. A wine glass might be in one piece, or it might be in three pieces (foot, stem, bowl), fused together.
Less expensive crystal can be done in a mold and sometimes you will see a very faint line where the crease of the mold was and, in these cases, the pieces are usually identical.
I'm attaching a link to Kinsale's site. They feature an old method of deep cutting for crystal. If you were to carefully examine two identical vases, for example, you would see slight differences in the cuts.
Also, crystal has a high degree of lead content (24% - 33%), whereas ordinary glass has no lead in the composition. An exception to this is Moser's crystal line -- it has no lead.

Is Glass A Crystal

Crystal has some lead in it. The more lead, the "finer" the crystal is considered to be. It's the lead that makes glasses ring when toasted.
Most glasses today are not hand blown. They're mass produced using molds in a factory.

The meaning of crystal versus glass changes according to the country. The word "crystal" means, in most of the western world, the presence of lead. According to European Union rules, glass goods containing less than 4% lead are defined as "glass". Goods containing more than 10% lead are defined as "crystal", and goods containing more than 30% lead are defined as "highly leaded crystal". In the USA it is the opposite - glass is defined as "crystal" if it contains only 1% lead. In the Czech republic, the term "crystal" is used for any exquisite, high quality glass. Leaded crystal means crystal containing more than 24% lead oxide.
The presence of lead in crystal softens the glass and makes it more accessible for cutting and engraving. Lead increases the weight of the glass and causes the glass to diffract light. Glass can contain up to 40% lead, if maximum hardness is desired. On the other hand, crystal can contain less than 24% lead if it has a high proportion of barium oxide, which ensures high quality light diffraction.

the difference is crystal makes a musical note when plucked and glass sounds like a cluck sound not sounding pretty at all. Or you can fill it with water and rub the rim and it make a great sound

same design glass( newer) comes from a press. as for crystal it has a true lead content..
some glass is still blown , thats why it costs more.
