Dr Toner uses a different sugar, trehalose, as the vitrifying "cryoprotectant".

Vitrifying large organs like the brain can also result in fractures due to different cooling rates in different parts.

Fulgurites are formed when lightning strikes the ground, fusing and vitrifying mineral grains. The primary SiO2 phase in common tube fulgurites is lechatelierite, an amorphous silica glass. Many fulgurites show some evidence of crystallization: in addition to glasses, many are partially protocrystalline or microcrystalline. Because fulgurites are generally amorphous in structure, fulgurites are classified as mineraloids.

Chatsworth Calera also called Chatsworth Reservoir Kiln Site is one of the few surviving structures of the early 1800s lime industry. This kiln marked the introduction to California of the European industrial process for vitrifying limestone building blocks which were used in the construction of the San Fernando mission and other mission buildings. The word "Calera" is Spanish for "limestone quarry" or "limekiln". Chatsworth Calera is now located in Chatsworth, Los Angeles, California.

Sugars do not readily permeate through the membrane. Those solutes that do, such as dimethyl sulfoxide, a common cryoprotectant, are often toxic in intense concentration. One of the difficult compromises of vitrifying cryopreservation concerns limiting the damage produced by the cryoprotectant itself due to cryoprotectant toxicity. Mixtures of cryoprotectants and the use of ice blockers have enabled the Twenty-First Century Medicine company to vitrify a rabbit kidney to −135 °C with their proprietary vitrification mixture.

Historically, a person had little control regarding how their body was treated after death as religion held jurisdiction over the ultimate fate of their body. However, secular courts began to exercise jurisdiction over the body and use discretion in carrying out of the wishes of the deceased person. Most countries legally treat preserved individuals as deceased persons because of laws that forbid vitrifying someone who is medically alive. In France, cryonics is not considered a legal mode of body disposal; only burial, cremation, and formal donation to science are allowed.

Cells may be cooled at an optimum rate to a temperature between −30 and −40 °C before being plunged into liquid nitrogen. Slow cooling methods rely on the fact that cells contain few nucleating agents, but contain naturally occurring vitrifying substances that can prevent ice formation in cells that have been moderately dehydrated. Some cryobiologists are seeking mixtures of cryoprotectants for full vitrification (zero ice formation) in preservation of cells, tissues, and organs. Vitrification methods pose a challenge in the requirement to search for cryoprotectant mixtures that can minimize toxicity.

Young's experience of firing ceramics, together with his familiarity with the region as a local surveyor and his amateur interests in geology enabled him to conceive of a heat-proof, blast-furnace brick, using silica found in large deposits at the head of the Neath Valley. The process of "vitrifying" the walls of a ceramic brick-built furnace had been patented by William Harry, of the Swansea Valley in 1817, but Young's solution was to build the whole furnace from a "silica firebrick," made with a 1% addition of lime, to bind the blue-grey "clay" of the Dinas rock. The idea being that the interior of the blast furnace would vitrify and be vastly more durable and ultimately economical, than a mere veneer of silica within a comparatively fragile ceramic shell. Young made early experiments with the recipe and fired his trial bricks at the Nantgarw Pottery kilns, while he and Pardoe finished the Billingsley porcelain for sale between 1820 and 1821 when he finalised his recipe.
