TECHNOLOGIES & PRODUCTS
Using fire, Craftsmen/women manufacture the glass products according to customer needs.  Onizuka Glass’s technology started from here.  Now, techniques and technologies are passed on, from the senior craftsmen to the juniors.  Not only passing it on, but also continuously being improved.  We can process various kinds of materials, such as quartz and soft glass (flint glass, etc.).  For example, graded seal is a technique to connect quartz and soft glass.  It is useful when bonding metal electrode and quartz.  Our unique technology is applied to a wide variety of high-performance products.  This is the base of our technology, since Onizuka was established and it will be continued on.
