3M's 507 Buttercut sandblast material is 45mil (1.4mm thick). Supplied rolled, approx 62cm x 60cm.
Buttercut is the resist of choice for deep sandblasting. It is a highly durable green rubber sandblasting stencil that has superior adhesion to glass. Buttercut stands up to the stresses of deep glass carving. With Buttercut its also easier to see the layout with more colour contrast and is easy to remove once the project is complete.
Buttercut has also proved excellent for pre-cutting and application to a roller which is used to impress a continuous pattern in an olivine-sand and plaster mixture spread on a kiln bed. The depth of the Buttercut is ideal, leaving a clear, clean embossed pattern on glass which has been slumped on to the kiln bed.
