However, because of its high heat resistance, the abrasive effects of the chemical composition of the alloy and the
self-hardening ability [1], these alloys are incorporated into the ISO S group, the group of materials which are difficult to machine.
This approach was selected in order to minimize patient morbidity, surgical time, and cost, but mostly in an attempt not to displace the mucogingival junction and to allow for the spontaneous formation of new soft tissue over the postextraction grafted site, as described in similar studies using
self-hardening synthetic bone grafting materials [11, 28].
Self-hardening clay is exactly what it sounds like.
* White earthenware or stoneware (may substitute
self-hardening clay)
When [he] shadow-boxed, shadow-bullfought, or cauterized scratches with a burning match to prove his stoicism before pain, his
self-hardening process left me embarrassed."
In noting how Hemingway, Ford Madox Ford, and other writers are congregating in Paris, he says: "Among so many writers, one might pursue the phantom--intellect--but encounter mere shop talk and the diplomacies of writers pretending to be awed by the others' success." He is repelled by the postures that Hemingway (here "Forrest Pemberton") puts on: "When Pemberton shadow-boxed, shadow-bullfought, or cauterized scratches with a burning match to prove his stoicism before pain, his
self-hardening process left me embarrassed."
Penloc R2 is a
self-hardening resin retaining compound, designed to securely retain bushes, bearings and other cylindrical parts.
Developing a set of
self-hardening, inflatable wings wasn't easy.
* As a time and cost saver, use one of the
self-hardening clays that can be painted with tempera paints.
Research on calcium phosphate chemistry at NIST led to the discovery of the worlds first
self-hardening calcium phosphate cements (CPC) in 1987.
