Lead Crystal. Lead crystal is made from glass that has been treated with lead oxide and hand or machine cut to make facets. This gives the glass a higher index of refraction and creates an attractive sparkling effect that is prized throughout the world. Englishman George Ravenscroft is credited with discovering lead crystal in 1676.
In tort law, a duty of care is a legal obligation, which is imposed on an individual requiring adherence to a standard of reasonable care while performing any acts that could foreseeably harm others. It is the first element that must be established to proceed with an action in negligence. The claimant must be able to show a duty of care imposed by law which the defendant has breached. In turn, breaching a duty may subject an individual to liability. The duty of care may be imposed by operation of law between individuals with no current direct relationship (familial or contractual or otherwise), but eventually become related in some manner, as defined by common law (meaning case law).
Instead, there is an assumption in criminal law that tort law exists to compensate the victim for the victim's financial harm. Tort law is a kind of civil law, like family law, property law, and contract law. Torts are some general standards of civil conduct.
