Blaa Blaa A blaa , or Waterford Blaa, is a doughy, white bread bun (roll) speciality; particularly associated with Waterford, Ireland. It is currently made in Waterford and County Kilkenny and was historically made in Wexford. Blaas are sold in two varieties: "soft" and "crusty". Soft blaas are slightly sweet, malt flavour, light but firm in texture and melt in the mouth. Crusty blaas are crunchy at first bite, then chewy with a subtle malt taste and a pleasing bitter aftertaste from the well cooked, dark crust. Blaas quickly lose their freshness and are best consumed within a few hours of
Boule (crystal) fashion. As the seed is extracted the silicon solidifies and eventually a large, cylindrical boule is produced. A semiconductor crystal boule is normally cut into circular wafers using an inside hole diamond saw or diamond wire saw, and each wafer is lapped and polished to provide substrates suitable for the fabrication of semiconductor devices on its surface. The process is also used to create sapphires, which are used for substrates in the production of blue and white LEDs, optical windows in special applications and as the protective covers for watches.
