A. is the head hollow so you can fire it? If it's not hollow (wall thickness should be not much more than an inch) it would explode when you fire it. If you can fire it, you could use oxides, underglazes, and a wide variety of of glazes. Talk to whoever would fire the head for you about advice for that. If you can't fire it you can paint it with various paints, Acrylic paints will be the easiest. If you want you could also glue things on, have a fork come out of it's ear...

What is the effect of surface contamination on a casting of Inconel 718?
Q. The issue is that I have a casting that has some blueing on the surface. Is this the result of heat treating the casting in an air furnace versus a vacuum furnace? Also, what exactly is surface contamination for this material?

A. It very well may be surface only discoloration...buff an area and see.Just because it blued a little is no reason to think it is contaminated deeper. The blueing is oxadation due to the heat.

How can you make a solid surface countertop (like Corian) shine like a granite countertop?
Q. We just got a Corian solid surface kitchen countertop installed. Even with the brand new surface, the certain dullness of resin material is evident. Is there any way to treat a solid surface so that it would shine more, much like its granite couterpart?
Asked by Benkay - Thu Jan 18 23:22:49 2007 - - 5 Answers - 1 Comments
A. The usual complaint people have about granite is that it is so shiny that every fingerprint and speck of dust shows up on it so they wish it wasn't shiny. The Corian people brag that they have textured the surface so that it doesn't show prints or dirt as easily. If you want to fight that get paste wax and a buffer and go over the Corian to get it shiny. I am sure your next Yahoo question will be "how do I get this annoying shine off my Corian."

A. The block is put in an acid solution for a short amount of time. This can help with sectioning of partially calcified tissue but will only work for the first couple of sections - decalcification of the whole specimen needs to be done prior to embedding.

Worm/larvae/grub on the surface of my pond?

What process on metal makes the surface rough and sparkly?
Q. Polishing a metal makes it reflect light like a mirror. How does one make metal sparkle under light. Presumably the surface needs to be roughened, as well as polished, so that it glitters this way. Is this burnishing? Or is it something else? Does metal look aesthetically pleasing or not when treated this way?
Asked by okei - Wed Feb 24 00:15:43 2010 - - 3 Answers - 0 Comments
A. Burnishing is one way, but if you're talking about decorative purposes, you could look up on metal-leafing, which refers to the technique of mechanically adhering metal leaf to a surface. The leafing would give the surface some texture, and it's still shiny and sparkly. Here are some images for you -- Or what about gilding? Gilding is also a decorative technique of applying fine metallic-leaf or powder to solid surfaces such as wood, stone, or metal. Here's the link I took the info from -- Another one of your little "projects", huh?

A. Don't use an ordinary kitchen cleaning product to clean granite. The newest technology uses peroxide and detergents to penetrate soiled areas. Simply spray a product such as Bio-OX Citrus Concentrate on the soiled area, allow it to penetrate for a few minutes, then wipe clean. Baking soda can be sprinkled on for a more abrasive cleaning action. Repeat if necessary. Granite can also be cleaned using warm, sudsy water (a mild detergent such as a grease cutting dish detergent or laundry detergent is fine) or a solution of borax and water.

How do you get neon tetras to swim to the surface?

A. They may come to the surface for food if you dont feed them for a couple of days, but they are basically a mid-water fish. You could try some frozen bloodworms, they slowly sink in the tank and drift into the neons zone. Another option is to pre-soak the dried ones in a cup so they sink right away. Ian

The moonbases should be constructed by then which would serve as a launching point for manned Mars missions but there are many technical problems that still remain to be worked out. A new space fleet still needs to be constructed and more study needs to be done regarding the Martian dust storms to make the mission safe.

Asked by winterdawns - Thu Jun 7 04:44:40 2007 - - 3 Answers - 0 Comments
A. On an incisor, unless there is no tooth adjacent to it to allow direct access, the Dr. will need to cut into the tooth from the lingual to reach the mesial decay. Thus you will be charged for a 2 surface restoration. This is the same thing that is charged on a posterior tooth with mesial decay where the Dr. has to cut in from the occlusal to reach the mesial. The dental assistant needs to talk with her employer about this as she's badly misinformed. Sooo, use your dental floss each day so you don't get interproximal (between teeth) problems!

Index of refraction on the road surface Physics problem?
Q. Consider a common mirage formed by super-heated air just above a roadway. A truck driver whose eyes are 2.00 m above the road, where n = 1.0003 looks forward. She perceives the illusion of a patch of water ahead on the road, where her line of sight makes an angle of 1.30 below the horizontal. Find the index of refraction of the air just above the road surface. (Suggestion: Treat this problem as one about total internal reflection. Give your answer to 5 decimal places.)
Asked by JH - Sun Feb 8 02:07:35 2009 - - 1 Answers - 0 Comments
A. Light is usually absorbed by the road since it is black (transmitted into). However due to total internal reflection it bounces off the road and appears as a slick patch. It's misleading because the internal area is the air. They should call it total boundary reflection. Draw the ray from your eye to the road, then bouncing off there to the sky at the angles specified in the problem. For reflection, if a ray hits the road at 1 degree above the road, it will bounce off at 1 degree above the road too. That's specular reflection.

For reflection, if a ray hits the road at 1 degree above the road, it will bounce off at 1 degree above the road too. That's specular reflection.
