Winterstone Casting 2000_50 Lb Bag (247003)
An engineered formulation developed for producing permanent sculpture and architectural ornamentation using either thin-shell lay-up or solid casting techniques.

WINTERSTONE is a dry white powder --- a complex multi-component mixture of several cements, mineral fillers, copolymer and beneficient additives which when mixed with a nominal amount of water, produces a medium which gradually sets into a stone hard material. The hardening process is a result both of internal reactions with the mixing water and external air-drying.

WINTERSTONE has the following characteristics:
* fineness and hardness for easy carving and finishing
* does not require a secondary process such as firing or casting
* can be worked or tooled to produce various surface textures and finishes
* can be integrally pigmented or externally patinated
* does not require sophisticated or expensive tools or equipment
* safe, non-toxic, and easy to use
* weather resistant


General Information
The Patina on a sculpture generally exerts considerable visual influence on the overall aesthetic character of the sculpture -- like icing on a cake -- and can enhance the sculpture's final appearance by achieving a particular colour, by accentuating or subduing certain aspects, by creating an aged look or by making the surface appear like another material such as bronze, granite, terra cotta, or wood.

Patination is an art involving many and varied methods of aging or colouring. Patination of WINTERSTONE can be enhanced by mixing oxide pigments and/or metallic powders integrally within the WINTERSTONE mixture. By treating the cured and hardened surface with the appropriate reactive chemicals unique and permanent colours and metallic effects can be produced. As such, the Patina is "part of the surface" and will not fade, chip or peel -- as compared to surfaces coated with acrylic stains or other types of topical coatings which can weather off quickly and may delaminate.

The number of Patina effects possible is virtually unlimited and depends only on the artistic creativity of the sculptor/patineur. The desired Patina effect may be summoned up from any one or combination of numerous variables available to the sculptor/patineur:

  • The amount and colour of oxide pigment used (if any).
  • The amount and type of metallic powder used (if any).
  • The concentration and composition of the chemical solution used
    to react with the hardened WINTERSTONE surface.
  • The concentration and composition of the chemical solution used
    to react with the incorporated metallic powder.
  • The technique used in applying the reactive chemical solutions.
  • The texture of the hardened WINTERSTONE surface.
  • The type of sealer used.
