com Seedling Baby's Handprint in a Tin THIS kit allows parents to record a memory of baby's little foot or hand forever, using the soft air-hardening
clay, acrylic paint, and paint brush included in the kit.
They are air-hardening
binding materials such as building gypsum and lime, cement concrete, building mortar, wall and roof materials, construction steel, wood, waterproof materials such as asphalt, building plastic, heat-insulating and sound-absorbing materials, and finishing materials.
Grasello di Calse, based on air-hardening
lime, provides a high-quality decorative gloss finish in soft shades that vary depending on the application technique.
SARGENT ART announces that its Sculpt*it[TM] Colors Air-Hardening
Sculpting Materials are now available in white and five bright new colors (red, blue, green, violet and yellow).
The article about making a "Democratic Axe" said to use "annealed (temperable) steel"--this description covers many different types of steel; some, such as air-hardening
tool steels, would be ruined by quenching in water.
The local limestone is the perfect building material, easy to quarry, air-hardening
and long lasting and though some people may grumble about change, it is worth remembering that it was change that ensured the survival of so much of the Cotswolds' period architecture, namely agricultural decline.
steels cool more uniformly, so distortion and risk of cracking are lower.
TD is effective with air-hardening
cold and hot working die steels such as A2, D2, and H13, high speed steels, and cemented carbides.
At one time, they were the most used, but as service requirements became more critical, there was a significant shift to oil-hardening and air-hardening grades to minimize distortion after heat treating.
The column on the left contains steel names beginning with "air," signifying they are air-hardening grades.
