Latex mask
From Wikipedia, the free encyclopedia
Latex mask generally refers to a full-head enclosure or disguise, often worn by someone as a part of a costume and made from synthetic latex rubber. Latex masks are particularly popular around holidays such as Halloween. Latex masks were among the earlier arts, typically in film but applying also to the theatre, originally called 'special effects,' condensed later to 'F/X,' before the term became associated more frequently with the creation of computer-generated imagery such as the work of SGI (Silicon Graphics Corporation of Silicon Valley) in its work on 'creating' dinosaurs for the film 'Jurassic Park.'
Latex masks are generally made in several stages. The first stage may begin with a clay-sculpted 'positive' or 'male mold' of the character. A plaster mold is then made of the sculpture, capturing all of the detail. The plaster mold is generally made in two-pieces for a full-head mask. Another popular method of creating such masks is to make a life mold of the subject in which he or she reclines in a chair, has his or her hair protected by a skull cap, and has plaster of paris placed over the head (breathing facilitated, typically, through straws placed in the nostrils). This is usually done in two parts--front and back. The division may be established through the use of a template of the top-to-bottom outline of the head and neck of the person being 'cast,' with a parting compound such as a lubricant being placed on the template to enable the easy separation and removal of the two parts of plaster. After the two parts have been removed and have been allowed to dry, they are re-united to form a 'female' mold into which plaster may be poured to re-create the image of the original cast head and features, in 'male' or 'positive' form.
Once the male or positive mold has been made the split external halves of the female mold is split off. The new 'positive' is carefully removed and cleaned. It may be altered through the superimposition of modeling clay that builds upoon the original 'male' mold to establish different features for a final, external character mold that can itself be re-cast. Whether altered or not, the mold is re-cast to form a hollow negative of the design and latex rubber is poured in and allowed to sit for a short time before the excess is poured out.
After the latex rubber has dried inside the mold, it can be peeled out and painted as desired. What comes out of the mold is now the 'positive' version of the latex mask.
In complex transformations, both the original, unaltered positive mold and the altered, character molds may be used to achieve high levels of fit and fidelity. In such cases, thin 'takes' of both the changed and original may have the void between them filled with liquid latex so that the interior fits the original wearer and the exterior matches the desired character precisely.
One of the great pioneers in the creation of latex masks was the late Don Post, whose work in the film and television industry spanned decades and whose son, Don Jr., still works in the industry. Don created many of the greatest latex effects, including the masks used in Rod Serling's TWILIGHT ZONE, in MISSION IMPOSSIBLE and other major productions (it must also be noted that 'trompe l'oeil' photography was often used in MISSION IMPOSSIBLE to create the impressions that characters had been 'reproduced' through the use of masks). Don used an old dentist's chair, heavily splattered with plaster, in which his subjects sat for their molds.
Don Post was also responsible for the original King Kong 'ape' (the figure was much larger than a human) and for the full body costume worn by the 'swamp creature' in THE CREATURE FROM THE BLACK LAGOON.
