Putting Patterns on Porcelain

Monday, November 29, 2010

Today there are many options for putting colorful patterns onto porcelain china. Some, like decoupage, waterslide decals and air-dry paints like Delta Air-Dry PermEnamel are within the reach of any home crafter.

Others, like dye sublimation printing, transfer printing and hand-glazing high-fired pottery require substantial investment in equipment and are best suited to well-capitalized businesses and artists' cooperatives.

The two classic ways of putting patterns onto porcelain, hand-painting and transfer printing, still exist today. In addition, there is a high-tech version of waterslide decals used commercially which consists of screen-printing decals with glazes and applying the decals to the porcelain. In each case, the pottery is high-fired before decorating to at least cone 6. [Cone is a measure of heat absorption resulting from heat applied over time. Cone 6 translates to between 2165 and 2269 degrees F (depending on how fast the kiln heats – or ramps – up).] Such high-firing produces the hard almost-translucent quality of genuine porcelain. Then the piece is decorated and lightly fired repeatedly to melt and fuse the glazes to the porcelain.

Incidentally, the term "porcelain" has been applied more and more broadly as new techniques developed. Ask any potter to define "porcelain" and he will likely give you the classic definition. To a potter, genuine porcelain is high-fired (cone 6 or higher) white clay that is at least somewhat translucent. It has a large proportion of kaolin clay, with the remainder being primarily feldspar and silica. This clay composition accounts for the pure white gleam of porcelain




Artisans who paint porcelain (rather than actually make it) refer to three grades of porcelain: hard-paste, soft-paste, and bone china. They all contain kaolin but only hard-paste has feldspar and silica and is high-fired. The high temperatures cause the body and the glaze to fuse. When hard-paste porcelain is broken, it is impossible to distinguish the body from the glaze.
Soft-paste porcelain adds ground glass or frit (material for glass that is not yet fused and vitrified) and is fired to between cone 01 and 1 (1999 to 2109 degrees F). Because soft-paste porcelain is fired at lower temperatures, it does not completely vitrify and remains slightly porous. When soft-paste porcelain is broken, you can distinguish a grainy body covered with a glassy layer of glaze.

Bone china has bone ash added to the kaolin and vitrifies (becomes glass-like) somewhere between cone 2 and cone 5 (2034 to 2205 F). Though not as hard as true porcelain, bone china is more durable than soft-paste porcelain. The bone ash greatly increases the translucence of the porcelain.

Finally, go to a tile store and look at their "porcelain" tiles. If you turn them over, you will see base clay ranging from white to brown to gray. The definition of "porcelain" in the tile industry has nothing to do with the clay content or level of firing. Rather, tile manufacturers define as "porcelain" any tile fired to the point where it absorbs less than 3% moisture.

If you're searching for a Pit Bull terrier puppy but are unsure about where to look for one, this is an important article for you to read. Many people are afraid to ask questions when they speak with breeders and this is the first hurdle that you need to get over. It is vital for you to ask questions when you are speaking with different breeders. Below is a list that I've created of some very important things you should look for and ask of the Pit Bull terrier breeders you're considering doing business with.

1. Does the breeder breed several different types of dogs? This can often be a red flag and you should try to stick with breeders who only work with American Pit Bull Terriers.

2. A responsible Pit Bull breeder will be able to tell you the negative characteristics and health issues of his breeding line and also what he has done over the years to improve that aspect of his dogs.

3. Can the breeder thoroughly explain to you how he selects dogs for breeding and what characteristics they will most likely throw?

4. How often does the breeder have litters of puppies? Breeders who have many, many litters each year may not be a good choice.

5. Is the breeder involved with Pit Bulls on a larger scale than just breeding them?.

6. Does the breeder keep in touch with those who have purchased puppies from him? Breeders who sell pups and then have no idea where they end up should be avoided.

7. Where does the breeder keep his puppies at before they are sold? Are they well socialized?

There are many other things that you could ask the Pit Bull breeders that you speak with, however the above list will give you an excellent start and greatly improve the chances that you'll end up with an excellent Pit Bull terrier puppy.

Invitro Fertilization - The Male Point Of View

0 comments
For many couples, the introduction of children into a relationship is the ultimate fulfillment and goal of the relationship. Unfortunately for some of the couples, medical conditions may exist that will prevent natural fertilization. In those cases, the affected couple may opt to conceive via Invitro Fertilization. For those couples of decide to pursue Invitro fertilization, the time leading up to the fertilization will be very process orientated - there will be consultations, evaluations, forms, literature and a lot of listening. At times it may seem overwhelming and frightening.

As the male participant in the process, your involvement will be largely in a support role, as most of the work that will need to be done will be with the female partner. To help make the process as easy for her, there are a number of facts to keep in mind and a number of actions you can take to help keep your partner's spirits up and to help her in the necessary steps to achieve a successful fertilization.

- You and your partner may struggle with the fact that you are unable to conceive by natural means. However, keep in mind - although it may not be a natural form of conception, the end result and the end goal of the process is the same - a healthy child. The two of you are merely trying to maximize the possibility of a healthy & successful pregnancy. Talk through this point and be open to her feelings.

- There will be a lot of absorb about the process, so take notes and do your research.

- Some of the medications required for the process will need to be administered via injection. Offer to administer the shots if your partner is not comfortable doing so, and keep in mind that she will most likely be very sore in the injection spots because of repeated shots. A little tender loving care will help keep her confident and comfortable. Also, a heating pad may help during periods where her abdomen is very tender.




- Your partner will be asked to take very specific medications, at very specific times and she will

need to consult with the doctor on a somewhat frequent basis, often times on very short notice. Make sure to keep your schedule as free as possible so you can assist in transportation and medicine administration as needed.

- Your partner may experience emotional mood swing because of some of the meds. One minute she might be sitting at the table reading the newspaper, the next she is crying about something unrelated. Be prepared, be supportive and remember that her mood will return to normal in time.

- Always remember - you have the easy part of the process!

Invitro is not an easy process, especially compared to natural fertilization. But with care, cooperation and a willingness to help out where needed, you can be active and helpful throughout the fertilization period.

Should A Mom At Home Own An Otoscope In Caring For Her Baby or Her Kids?

Friday, November 26, 2010

We are all familar with the sight of our family doctor using a diagnostic tool called an otoscope to take a look into our ears when we seemingly have some ear infection, or some pain arising from the ears.

That is all well when the doctor, as a physician handles that task.

But the question is this: " Should a stay-at-home mom own an otoscope and perform ear inspections herself on her baby or her kids?"

To answer that question, I researched the internet and also look at feedback from many stay-at-home moms, to tap their experience and to see what they are doing.

The answer was a overwhelmingly "YES".

Moms-at-home feel that they should take a more active role in ensuring the health of their children, rather than to have this role performed solely by their physicians.

Moms-at-home feel empowered when they own an otoscope and can use it to identify potential problems in their infant's ears, especially when they find their babies tugging their ear lobes or crying with some form of discomfort arising from their ears.

When they own an otoscope, they can use it readily to take a look into their infant's ears to see whether it is reddish, which will suggest a ear infection just starting off and then to refer their children to their pediatric or their child specialist for further diagnosis and treatment.

This gives them comfort and peace of mind that they can nab beginning ear infections in the early stages rather than finding out about these ear infections in their infants at 2 am in the hospital's emergency rooms.

Otoscopes come in different quality and at different prices. From a twenty dollar model to a quality otoscope such as the Welch Allyn otoscope which can cost a few hundred dollars, the key to a good otoscope is to ensure the lens is powerful enough to provide good manification.

Irregardless of the make or model, the majority of moms-at-home are thankful for this invention called an otoscope that is proving to be useful in helping them identify ear infections fast.
