Could drilling holes into crystal be a source for lead poisoning?
Food or drink stored in a lead crystal piece can be contaminated by lead from all surfaces of the crystal which come into contact with the food or drink. The exposed interior of a lead glass crystal piece (a drilled hole) is no different from any other exposed surface of the same piece. The drilled hole simply exposes more surface area, thus providing more potential for lead contact.
What is lead crystal glass made of?
The inclusion of at least 24% lead oxide in the composition is required by law for crystal to be called full lead crystal. The lead lends brilliance and weight to the product. Crystal without lead is still crystal, i.e. clear glass, however, it is more commonly perceived as &quotglass". The lead also make the crystal softer and more conducive to cutting. This is why the lead crystal is cut and for the most part, the unleaded crystal is not cut.
Does glass have lead in it?
Some glass has lead in it, specifically crystal glass. The lead acts as a flux in glass, allowing the grains of silica sand to be melted at a lower temperature. Glasses are generally denoted by their flux, so you get soda glass, flint glass, borosilicate glass, lead crystal etc. Lead also lends crystal the attribute of a high refractive index, making it a very clear glass and also soft. It can be easily cut with designs and polished. George Ravenscroft developed the first viable lead glass.

what is the value of lead Crystal?
The lead in the crystal gives it a brighter shine. The lead also allows the glass to be cut in intricate and unusual ways. Each piece has to be individually crafted - I guess "craft" is a good word to describe the making of lead crystal pieces. Ordinary glass can be mass produced and molded to form the design- not crafted.
