In 1970's it started being used for glass art, too. There are several abrasive-etching techniques, such as: surface etching, carving, shading, etc.

	Clean the surface of the glass with a cleaner inorder to apply the resist easily.		Clean the surface of the glass with a cleaner inorder to apply the resist easily. This one is cased glass purple & yellow.
	Apply the resist to the clean surface of the glass. First, cut slits where the resist needs to comform to the compound curve. Second, squeegee the resist down on the glass, avoid trapping air bubbles. And then, check for air bubbles or areas not covered by resist.		Draw the design to the resist. Apply the resist to the clean surface of the glass.
	Draw the design in the pencil on the surface of the resist.		Cut out the design with my stencil knife carefully. Remove off the background.
	Trace the design with a pen		Place the glass in the blasting cabinet. Move the nozzle back and forth to remove all purple parts.
	Cut each outline with my stencil knife carefully.		The finished piece shows yellow part.
	When all elements have been cut, peel some elements before blasting.		Assign a number to each element, identifying the blasting stage for that particular element.
	Place the glass in the blasting cabinet. Move the nozzle back and forth. Peel the resist and blast each parts again & again.		The completed etching.
	Remove the resist and clean the glass.	the title "Summer Flowers"(clematis) This work was accepted for 2009 year's The 68th. Syukougei Art Exihibition. It was placed at TOKYO METROPOLITAN ART MUSEUM..
