Using Polypropylene Core Trays Is a Good Advantage

Posted by admin - May 12th, 2010

With the coming of plastic core trays, a lot of industries have experienced improved efficiency and output. The problem with this, though, is that there are still a lot of people who doubt using plastic core trays out of their ignorance of the benefits that the core trays could give. To shed more light and convince more people, here are some of the advantages of using plastic core trays.
Core trays that are made of polypropylene have superior strength than those that were not. Polypropylene core trays usually have better quality, thus, ensuring safety and endurance. Polypropene (PP) is a thermoplastic polymer and is widely used in a lot of industries. Aside from core trays, other products made from the use of PP are automotive components, laboratory equipment, and the likes.
Polypropylene has a high level of resistance to organic chemicals found in drill core recovery, therefore you will experience no corrosion or contamination of the core from rust or residue left from the galvanizing process that steel trays go through. Also, polypropylene is non magnetic which means you can evaluate the core without interference.
Core trays need to be a one piece molding that have no pop rivets and welds which means increased product strength, and less damaged and unusable trays, dramatically reducing wastage. Also, rounded edges mean no more dangerous sharp edges, leading to improved safety when handling. In addition, because we use plastic we can color code the core trays which allows ease of identification in storage.
Core trays made of polypropylene are more tolerant with impacts, thus they do not break easily and do not need frequent replacement. In fact, these core trays are very recyclable. This goes to show that you can save a lot on your expenses. Also, since plastic does not get painfully hot when left under the sun unlike metals, you do not have to worry about handling problems.
If core trays made of polypropylene could give you this much advantage, why settle for something much less? Imagine what you would get if you use these kinds of core trays: reduced cost, lessened handling problems and improved productivity.
Yandina Plastics was able to develop a new range of core trays which will benefit customers a lot as these trays can be neatly placed inside of each other when being shipped empty, leading to significant savings in freight. Also, when filled with core, they simply stack on top of each other without touching or damaging the core in the tray below.

Before You Venture into Chocolate Tempering, Read This

Posted by admin - February 26th, 2010

You may be devoid of good judgment if you think that chocolate candy making is not a difficult thing. Maybe having all that you need, like a thermometer, spatula, double boiler, cookie cutters, candy molds, cookie sheets, and chocolates, are within reaching distance.

Actually preparing chocolate candy seems straightforward, too. You melt chocolate strips at low or medium heat on a double boiler, stirring now and then so as not to burn the chocolate, then you move the chocolate mush and pour over a cookie sheet to cut into bars, or onto chocolate molds to create different shapes, or even robe fruits with the molten chocolates for fruity-cored candies. You chill and serve, and your friends and relatives are happy.

But if you want to sell chocolate candy, then you’ll need that thermometer to always be near at hand because it’s for checking temperatures during tempering, a series of melting, cooling and re-heating stages to make chocolates attractive and therefore sellable for profit.

The shine, smoothness, snap and creamy texture are not original to chocolates so you need to temper because it’s what makes chocolates appealing to buyers. Correct chocolate temperatures are an important part of tempering because if you don’t maintain accuracy, chocolates will revert to its distempered state after melting so you’ll need to re-temper again.

Every chocolate type (white, dark, milk) has different tempering temperatures. It the distinctive polymorphic behavior of the fatty acids within cocoa butter that makes tempering a complex activity, and the reason for the need to keep temperatures accurate. These crystals form and multiply at six different and particular temperatures so temperature variations will always lead to tempering failure.

You should also know that the type V and type IV crystals can multiply together; keeping temperatures constantly accurate will discourage the type IV crystals, which melts away easily at room temperature, from proliferating.

Tempering could be carried out manually or by using a chocolate tempering machine. Especially when you’re tempering several pounds of chocolate at a time, you’ll need to automate tempering. It has a microprocessor that controls temperatures and directs the tempering cycle accurately so you can keep chocolates tempered while you’re working, or even holding them tempered overnight.

Artisan chocolatiers, however, prefer tempering by hand as they are in the specialty chocolate niche. You’d do well, though, to learn their technique even with a tempering machine as there may be times when you won’t have electricity. In which case, manual tempering will come handy and helpful.

Two tempering methods are available: tabliering uses a marble slab to lower chocolate temperatures; and seeding uses “seeds”previously tempered chocolate solids cut into small piecesto lead in the crystallization process so only the right crystals get produced.

You’ll need to keep repeating the tempering process if the temper of the chocolate gets ruined because you forgot to adhere to strict temperatures.

An Introduction to Street Art as Prints on Canvas

Posted by admin - September 10th, 2009

The public has had a love/hate relationship with graffiti. On the “good press” side, creatives like Banksy have made graffiti an aesthetic pleasure, applying stencils to produce technically tricky graphics with political points attached. This sort of graffiti was likely to get fashionable with the public and the artworld : visually pleasing and intellectually satisfying. This type of graffiti is now even acquired as prints on canvas, and hung on the walls of middleclass homes and office reception areas.

Yet, what of the common or garden sort - the tagger, the gangbanger sort - this sort of graffiti is often seen as hooliganism, an offence committed by the talentless. But is graffiti only an artform? To many individuals, it’s not only art, but a means to mark a neighbourhood, or even two fingers up at society : anti-establishment, anti-social, even anti-art.

Graffiti has always been a covert activity, although the results are very much public. The targeted audience is often unidentified. Is it for a rival gang? A message to a single person? To the public? Or….possibly it’s simply gratuitous and out of nothing else to do.

Whatever the reasons may be, there seems to be a permanent need to spray on walls. Some cities have acknowledged that graffiti isn’t going to go away, so they’ve designated zones where graffiti is allowed - normally uninhabited areas, but now and again more civic zones like temporary boarding surrounding urban construction sites.

Fire Pits Are Decorative

Posted by admin - September 4th, 2008


Since the beginning of times, fire has been the center of the community and it makes sense that today in the modern times, where everything is fast and technological, people go back to that basic concept. Fire Pits allow that to happen, right at the comfort of your home without having to worry and struggle like our ancestors used to do. Actually, fire pits allow getting fire and enjoying it, in style and fashion.

There are many different kinds of fire pits, made of all sorts of different material, even wood and they usually look very nice on a patio and create that cozy atmosphere that you often need to relax, have a drink in your gazebo or to entertain company or to have a romantic event. Of course, they also bring heat and help when it’s cold, as often they are much more powerful than most modern and electrical heaters. Fire pits are sold everywhere, even on line and are very easy to assemble. Then it’s just a matter of finding the right place where to put them and the wood to fire them up. Your place will be definitely enhanced by the addition of a nice fire pit and the rest is for you to enjoy and benefit from.

Lord Byron’s “She Walks in Beauty”

Posted by admin - June 11th, 2008

The poem I am going to deal with in this commentary is the description of a woman. It is somehow not very clear what is the relationship between the poet and her and what are the feelings involved between the two. Still, even if the poet’s feelings are not very clearly exposed, by the way he describes her, especially in the first two stanzas we can deduce the admiration the poet is baring for her. We can even say that he has unwillingly fallen in love with her, and is now writing this poem to explain both to himself and us the strange phenomenon that has taken place.

From this point of view, the theme of the poem is similar in a way with Keats’s “La Belle Dame Sans Merci”, as they both deal with the unexpected and unexplainable power of love. Still, if in Keats’s poem the love and the fulfillment of attraction are driven to an extreme, here this does not happen as the poet has coped with the thought of not having her.

As a structure, the poem consists of three stanzas, which can allow us to see a certain evolution of the poet’s states of mind in regard to the lady. The first stanza describes the woman from a more far-away perspective. It is the very moment of the attraction, when the fire is lit inside the poet’s heart, who is concentrating his angle of view, focusing more and more. In the second stanza the apogee of his feelings is touched as the poet is completely charmed by the woman, whose defects he turns into qualities and she is possessed by a “nameless grace”. The last stanza means coming back to earth, as the poet, though still persisting on her beauty has to notice that the woman has “a heart whose love is innocent” and “a mind at peace with all below”. The meaning of these lines is that the woman’s love and feelings cannot be disturbed. The poem has a calm ending, which together with the slow beginning and the intense second stanza make it very round and symmetrical on the whole.

In the first two lines of the first stanza the poet focuses on the appearance of the woman. The woman is seen as a cloudless and starry night. At a more superficial look this can be seen as a purely physical description, as the lady was probably dressed in a black dress. The stars, the glimpses of light would be her jewelry. Still, if we accept the idea that this is more than just a physical, almost literal description we should see what lies underneath the words. This metaphor allows us to understand the way the woman is perceived by the poet. She is the one that covers everything with her beauty, bringing light into darkness, as the stars do in a cloudless night.

Her aspect and eyes are a strange combination of dark and brightness. Though this contrast might sound a little bit strange at the beginning, it is a beautiful mean of expression. It describes the beauty and also the mystery that this woman has covered herself into. By associating these two characteristics to the eyes we get a better picture of what the lady looks like, as her black eyes are filled with brightness. In fact, this oxymoron is continued throughout the first two stanzas. The last two lines of the first stanza show the disappointment of the poet of not being able to make use of the light that comes out of this woman. He is denied the “heaven”, the privilege of enjoying wholly the beauty and light of the lady. This is where the dark emerges from, as all the brightness is shadowed by the sorrow of not having her.

The second stanza continues the description of the woman as a symmetrical combination of light and dark, of shade and brightness. This metaphor is meant to underline the complexity and harmony within the woman, not the superficiality or imperfection.

The view is now more focused than before and gets closer, visualizing the head of the woman in closer detail. Her hair is seen as the exponent of darkness, which is present in her “raven tresses”, in immediate contrast with the face. This one is filled with light. This perfect division of light and darkness, of “shade” and “ray” is associated to a “nameless grace” that is exercising its power over this very woman.

In this way the poet drives his divinization of the woman to a peak as he considers her gifted by a greater force with the immense quality of making cohabit both light and dark. The woman becomes the perfect shelter where the two opposite forces make peace and then cooperate in order to make her one of the most beautiful beings in the world. She is the one that helps and maintains this relationship of reconciliation as both forces are put in the service of a noble ideal, the ideal of beauty. Still, the combination of such different forces is made in perfect harmony, and the result is a “pure” and compact universe.

The last stanza leaves aside the coexistence of light and dark within the woman and tries to give a more general account of the woman and the characteristics that impress the poet so much.

The general word that seems to describe the facts in this stanza is serenity. Every quality that rests inside this being is in perfect harmony and peace. Things are described as if the woman is winning men’s hearts unwillingly.

The poet focuses again on the face and on the expression of the lady. The elements that seem to have a strong impact on men are her smile and her “tinted brow”. The falling in love of the men is done very softly, with a criminal-like perspicacity, as the men hardly realize the reasons, though they are obvious. On the other hand this seems to happen without her will, as she keeps her calm and imperturbability. Her mind is “at peace with all below”, and the love for her beloved has not been affected by the victims she has made during time.

This last stanza gives the impression of resignation at the thought of not having her. If the first two stanzas were full of impulsive thoughts that tended to describe her in a very exaggerated way, in this one the poet is brought more down to earth. We might even say that he is now describing her with a trace of sadness, of resignation at the thought of not having her. He is now trying to convince himself of the fact that an eventual relationship between the two of them or any other two persons would stand no chance as her heart is forever given.

If we now come back to the interpretation for the first stanza according to which the lady is dressed in a black outfit, we can find another possible trace of interpreting the last lines of the poem. Indeed, by associating the obsessive repetition of the black color with “a mind at peace” we can suppose that the woman is a widow. This is how we can find a meaning to the last verses. The author is sure that her love cannot be disturbed, as her beloved is now dead and nothing will be able to re-win her heart.

Next, we will have a closer look at the composition of the poem. We notice that the duality persists in what the words are concerned. Each first line of each stanza consists of two elements separated by comma, this double enumeration being carried on through the following lines. Either if it is two opposite or similar elements they are always put in the same phrase, in an unperturbed harmony:” beauty/night”, “climes/skies”, “dark/bright”, “aspect/eyes”, “shade/ray”, “more/less”, “tress/face”, “cheek/brow”, “soft/calm”, “smiles that win/tints that glow”, “mind/heart”. The poet, who perhaps wants to underline the happiness and fulfillment through finding of a mate, drives this duality to obsession.

We find the same duality in the succession of the lines inside the poem- the form of the rhyme, that is. Indeed, a line ending in a certain termination is followed by a different one and then by another one, again different but similar to the first one. This allows us to notice the hesitation and alternation of feelings that takes place inside the poet.
The poem follows a basic iambic tetrameter with an unaccented syllable followed by an accented syllable. Each line consists of four meters with two syllables each, a total of eight syllables per line. The rhyme scheme flows as ABABAB CDCDCD EFEFEF. Alliteration is also used: “Of cloudless climes and starry skies,” in which there is a repetition of the “s” sound. The second stanza contains insight into “the dwelling place” of the woman’s thoughts, creating an insight into her mind by using alliteration. The repetition of the “s” sounds is soothing in the phrase “serenely sweet express,” because Byron is referring to her thoughts, and her thoughts are serene and pure.

The poem is special, also through the means of expressions that the poet uses. These are not of an extraordinary expressivity, but still are beautiful and add a little color to the poem. The first line contains two means of expression: “walks in beauty” and “like the night”. These metaphors are very helpful in depicting the woman, both to a physical and an overall extent. Further, the “light which heaven to gaudy day denies” is again a very expressive metaphor showing the power of such a beauty, as it can deny the happiness of a human being. With this, Byron transforms beauty in a defect and the beautiful woman into a cursed being, as involuntarily these can harm other people.

In the second stanza, the epithet “nameless grace” is associated to the beauty that lies inside the admired woman. More than that, the poet considers that beauty is a sort of spirit that lays inside the woman and that gives her glamour. This grace is present also in another metaphor, as it “waves”, the poet referring at the presence and the ways of manifesting of this spirit. The “raven tress” is an epithet meant to make us perceive better the blackness of the woman’s hair. In the same stanza we meet the inversion “thoughts serenely sweet express”, which does not hide any meaning beneath, but contributes to the image of the poem.

In the last stanza we can notice the apathy of the poet also through the poorness of means of expression. Indeed, there are no notable metaphors or epithtets.

The poem represents more than just a description of an attractive woman. It is an insight inside Byron’s mind and subconscience, a description of the effects of love. It is less important which was the real context in which he wrote this poem or which were the real elements that made him write the poem. The important thing is that by reading this poem our imagination has a certain freedom and in the same time is led by Byron, as he drives us to the checkpoints he establishes in the poem.
Thus we can affirm that the poem is an authentic piece of Romantic poetry, even if this current is by far non-conventional, but diverse. The feelings and the means of expression implied in the poem are definitory for Byron and also for the trend he was a part of.
