  1. In Topic: Blues and greens

    Posted 17 Jun 2013

    "Blue is the top choice for 35% of Americans, followed by green (16%), purple (10%) and red (9%)"
    "A preference for blue and green may be due to a preference for certain habitats that were beneficial in the ancestral environment..."
    (Source: Wikipedia).


    There is a definite snobbery amoungst some potters against blue.
    They think it is a beginner's colour and that they have somehow "advanced" to other colours/glazes.
    Is this perhaps because they think if they can mix their own glazes they can snub "ordinary" blue ?

    Dear Clay Tile Mom,
    stick with your blues and greens unless you have something special in mind.
    Most people like these colours and they are easy on the eye.
  3. In Topic: Increase the Strength of Low Fire Clay | Aggregates

    Posted 25 May 2013

    You are essentially after accoustic results with the characteristics that you mention, i.e. it should not ring, low resonant etc.
    It makes much sense to me what you find, i.e. a non-vitreous still porous, low fire body is better.
    It is all about how sounds travel through different bodies.
    Accoustically speaking, the "softer", more "spongy" a body is, the more it will absorb the sound and the less likely it is to vibrate.
    That is why hitting a glass, porcelain or metal bowl (sharp ring) is different to a wooden or terracotta one (dull thud).
    I think organic grog that will burn up (like ground coffee), leaving small pockets, would help in absorbing & dispersing the sound. (Sounds travel better through solids than gas). However for slip casting you will need very fine grog.

    I therefore think it will be difficult to get both a hard body and an accoustically dampening one, because they are mutually exclusive. That is what the science says.
    (I am not disagreeing with the expert results that say that you can get very strong earthenware, I just think that the harder (more solid/rigid) it is, the worse it will be accoustically, because sound travels better through harder/denser bodies.

    Wikipedia:
    "Sound travels faster in liquids and non-porous solids than it does in air. Sound waves in solids are composed of compression waves (just as in gases and liquids), but there is also a different type of sound wave called a shear wave, which occurs only in solids. ...The speed of a compression sound wave in solids is determined by the medium's compressibility, shear modulus and density. The speed of shear waves is determined only by the solid material's shear modulus and density".

    "Thus the speed of sound increases with the stiffness (the resistance of an elastic body to deformation by an applied force) of the material, and decreases with the density"

    Note that "sheer modulus" is the rigidity.
    It would be wise to speak with a physicist or an accoustic engineer on how sound travels in different bodies if you have not already done so.

    "Strength" depends on function and use. Is the instrument going to be dropped often ? Hardness often goes with being brittle.
    Maybe the musician should respect the ceramic nature of the instrument, after all if you drop a violin you would also expect it to be damaged.
    I would be inclined to make the body of your musical instrument thicker in order to get more "strength", rather than making it harder and loosing accoustic properties.
  4. In Topic: How do you do this?

    Posted 24 May 2013

    Since this forum is about aesthetics, allow me to comment on the artistic aspect.
    In short: I find the bowl crafty but not arty.

    No doubt it is quite a technical achievement. The comments and interest on that aspect makes that clear.
    I like some of his other
    (more arty) stuff a lot.
  5. In Topic: Non-functional Pottery at shows - how to get the point across?

    Posted 24 May 2013


    I really do not see why you want to explain what Horse Hair or Raku is to potential buyers, unless they ask.
    You are not selling pottery classes, where people might be interested in how to do things.
    If you sell art then people will like it or not, you would not normally explain how you made it, whether it is a painting or pottery.
    If you walk into an art gallery then things are usually on display without explanations on how it was made.
    Explaining the technical aspects of your art can in fact distract from it.
    So it does not suprise me at all that you experience disinterest from customers.
    Rather focus on the presenting and selling aspect - John Baymore has given you good advice.
    Good luck!

    Thank you! It appears like my figures ends up with the same mood that I'am in at the time of my life :-) About your hot tip-I'm working with clay every day so it could be dangerous in the long run ;-)

    HOT TIP:
    Have a glass of wine while you work with clay.
    The stem of the glass will get muddy but the wine remains clear.
