Ivory from Africa was widely sought after outside the continent by the 14th century due in part to the poorer quality of Asian ivory. [31] While Asian ivory is brittle, more difficult to polish, and tends to yellow with exposure to air, African ivory often comes in larger pieces, a more sought after cream colour, and is easier to carve. Ivory ...
Designing of inlaid articles is a highly elaborate process. There are sometimes more than 400 pieces per square inch in a work of average quality. [2] Thin rods of different coloured woods, ivory, bone, brass, silver, etc. were glued together into long bunches that could have a round, rectangular, or polygonal cross-section. [3]
When working with ivory objects it is important to wear white cotton gloves and if none are available be sure to thoroughly wash hands prior to touching the object. [8] Since ivory is a porous material it is susceptible to staining. Ivory will yellow and/or brown with repeated contact to skin, fatty acids, and oils.
Ivory is a fragile medium; many 19th-century pieces were preserved because they were kept in a barrel of oil on board ship. Gary Kiracofe, a scrimshander in Nantucket, Massachusetts, advises collectors that if a piece looks dry, one should fill the center of the tooth with unscented baby oil and allow it to remain until as much oil as possible is soaked into the microscopic pores of the ivory.
Sometimes the cutting of the assistant is emphasised by sawing between the two halves of the box before sliding the dividers into place. Catches are released to allow the table to be separated into two halves along with the box. The halves are parted and the assistant thus appears to have been cut into two completely disconnected pieces.
Front Claps for corsets. A busk (also spelled busque) is a rigid element of a corset at the centre front of the garment. [1] Two types exist, one- and two-part busks. [2]Single-piece busks were used in "stays" and bodices from the sixteenth to early nineteenth centuries and were intended to keep the front of the corset or bodice straight and upright.
PARGC1A gene key to weight loss. At the study’s conclusion, researchers found that participants in the exercise group who had the most “skinny genes” lost up to 5 kg (about 11 lbs) during ...
Among these is laser cutting, where the design is drawn or imported as a CAD or vector file and each piece is cut separately; each different species of wood-and thickness-may need a specific adjustment of the beam power; the offset will determine the gap between the pieces. In some cases, the beam will leave a dark edge due to the high heat ...
