The Blow and Blow procedure or the Press and Blow process can both be used to make glass cups. The type of glass cup being manufactured determines which procedure is used. All glass cups begin as unprocessed materials. The desired qualities of the bottle are mixed into a precise mixture of silica (sand), soda ash, limestone, and cullet (furnace-ready, recycled glass). The combination is then melted in a furnace at high temperatures until it forms a molten material that can be formed. Soda-lime glass, the most common type of glass for food and beverages, will be produced by this mixture. Here are the main points:
1. Methods of Glass Cup Forming
2. Process of Pressing and Blowing
3. Process of Blow and Blow
4. Putting the Pieces Together
Before going into the forming machine, molten glass gobs are chopped with a precisely timed blade to guarantee that each job is of a similar weight. The weight of a gob plays a significant role in the construction of each glass cups. The moulded glass is made by gravity-feeding molten glass into a forming machine, where pressure produces the bottle's neck and basic shape. The form is known as a parison once the neck finish and general glass cup shape have been accomplished. One of two methods is utilized to achieve the final container shape.
In the glass cup industry, the Press and Blow process is the most often used method. It employs an individual section (IS) machine that is divided into various parts in order to create multiple containers of the same size at the same time. A shearing blade is used to cut the molten glass into a precise gob size. Gravity causes the gob to fall into the machine. The gob is pushed down into the mould with a metal plunger, where it begins to take shape and become a parison. The parison is then put into the blow mould and reheated until it is pliable enough to complete the glass proportions. Air is pumped into the parison after it has been reheated to blowing temperature in order to shape the container. Wide-mouth bottles and jars are frequently made using the press and blow method because their size allows the plunger to fit into the parison.
To make narrow containers, the Blow and Blow method is employed. It also necessitates the use of an IS machine, which gravity feeds molten glass into the mould. The parison is made by forming the neck finish and basic bottle shape with compressed air. After that, the parison is flipped 180 degrees and reheated before being blown into its final shape with air. The bottle is blown into the proper shape using compressed air once more. Blow and Blow are the finest procedures for making glass cups with varying neck thicknesses.
After the bottle has been completely made, it is removed from the mould and transferred to the annealing lehr, regardless of the procedure utilized. The bottles are reheated to about 1,050 degrees Fahrenheit in the lehr, then gently cooled to around 390 degrees Fahrenheit. This method allows the glass to cool at a consistent rate, reducing internal stresses that could cause cracking or breaking. The bottles are then thoroughly inspected to ensure that they comply with quality control standards. Any bottles with flaws, such as bubbles, cracks, or malformed portions, are taken off the line and utilized as cullet. All of the remaining bottles are classified by size and type. After that, the bottles are packaged on pallets and ready to transport.

When the candle in the candle cup burns, how to deal with the remaining candle cup? Regardless of whether it is reused or given a new purpose to the candle cup, the residual wax in the candle jar must be removed first. Do you know any method of cleaning wax? I will introduce you to the method of removing wax by freezing so that you can make better use of the candle jar.
Here is the list of the article:
l How to handle the candle cup before putting it in the refrigerator?
l How long does the candle cup need to be kept in the refrigerator?
l What should I do with the candle cups taken out of the refrigerator?
(1) Take a candle cup suitable for freezing. When there is only a small amount of paraffin at the bottom of the cup, the effect of freezing the wax is most obvious. In addition, this method also requires that the wick does not stick to the bottom of the cup. If there is a candle wick stuck to the bottom of the cup, the paraffin will not be completely clean. You can try the boiling water dewaxing described later.
(2) Many candle cups have narrow openings, so when you want to take out the wax, the wax block is easy to get stuck in the mouth of the bottle. The solution to this problem is to poke the wax into pieces with a butter knife. Frozen wax will become smaller pieces. Small pieces of wax are easier to pull out of the cup than large pieces of wax. You can also use this method to remove wax in candlesticks with special shapes.
Put the glass in the refrigerator to freeze. You need to put the candle cup in the freezer area until the wax freezes hard. This process can take as little as 20 to 30 minutes, and as long as several hours. Place the cup firmly and don't let it tip over. When water freezes, its volume increases, while wax shrinks. In other words, the wax will fall off the surface of the glass.
(1) Take out the candle cup from the refrigerator. When the wax is hard, remove the candle cup. Press firmly on one corner of the wax block to check whether the paraffin is frozen. If the wax becomes loose after pressing, it means that the wax block has been frozen and can be taken out.
(2) Pour the wax out of the cup. Turn the candle jar upside down and the wax lumps will fall out. If it does not fall, you can pick up the cup and tap it on the table a few times. You can also insert a butter knife between the wax block and the glass and press the handle to pry the wax block out.
(3) Remove the candle wick holder. If the wick holder is still stuck to the bottom of the candle jar, just insert the tip of the butter knife under the wick holder, and then gently press the handle, the wick holder will be pried open.
(4) Remove residual wax. At this time, there may be some scattered wax sticking to the cup. You can try to scrape off the remaining wax with a butter knife, wash off the wax with detergent and water, or wipe off the wax with a cloth soaked in baby oil.
(5) Reuse candle cups. Now you can reinsert the candle wick into the cup and pour new paraffin wax. You can also slightly decorate the cup for pens, cutlery, or other items.

There's a lot to do when you're getting ready to relocate. Every room must be completely cleaned, organised, and packed—and it appears that they must all be completed at the same time. However, some objects require more attention and care than others, and the glassware is one of them. Improperly packing glass cup, which is fragile and frequently precious, can result in permanent marring, major cracking, and even shattering. Let's go over the things you'll need and the processes you'll need to follow to properly pack and protect your glass cups. Here are the main points:
1. Gather your packing glass cups.
2. Protect the glass cup by wrapping it in packing paper.
3. Place bubble wrap around the glass cups.
4. Use dividers and fill in blank sections using dividers.
5. Make sure the box is properly sealed and labelled.
When you're organised, everything moves faster, and packaging glass is no exception. Here are the packaging materials you'll need to safely store your glass cups, vases, and other glass-based items.
l Tissue paper or packing paper
l Sheets of bubble wrap or bubble pouches
l boxes made of corrugated cardboard
l Tape for closing cartons
l Markers
Bubble wrap is an excellent kind of protection. However, if it comes into close contact with glass, it can create difficult-to-remove circular pattern marks. Packing glass with packing paper or tissue paper will avoid this issue, preserving your belongings from getting scuffed or blemished. To secure the loose paper, crumple it up at the edges or use packing tape.
This is where the show's star appears. Wrap your glass cups in bubble wrap thoroughly, gathering the loose ends, wrapping them over the product, and taping it shut. Bubble wrap sheets are the most readily accessible choice, but if you want to speed up the process of packing glass, you can use bubble pouches.
If your items are significantly larger or heavier than usual, you'll want to do one of two things: use larger bubble wrap or wrap the item in many layers. When it comes to packing glass, you can never be too careful, especially if what you're carrying is costly or sentimental.
Here, corrugated dividers are an excellent addition to your packaging strategy. They'll keep individual parts separated and in one place once they're assembled into their crosshatch-like pattern, lowering the odds of damage during transit or storage.
You'll want to make sure there's no room for anything to move or shift about once your glassware is wrapped and put inside the box. Use leftover packing paper or bubble wrap to fill in the gaps. Use just enough to keep everything in place without feeling suffocated or pressed.
Close your boxes with carton sealing tape, making sure the flaps are completely taped down and impossible to move. Use H-tape to patch any side-flap openings you detect if you're worried about dirt or damp coming through. Take a marker and write "Fragile" on the sides of a few of the boxes. It's no assurance that the suggested directions will be followed, but it surely helps.
It's easy for certain duties to slip by the wayside when you're moving, and it's easy to forget about them. Among all the things you have to deal with, properly packing glass cups is an important—but easy to overlook—task. We're convinced you'll be able to handle it with a little planning and this list of packing essentials.

Some scented candle has a calming effect, so many people who have been in contact with scented candles are willing to repurchase scented candles repeatedly. Some people even make scented candles at home. Compared with the candle cups produced on the production line of a qualified factory, what are some things to pay attention to when making scented candles by yourself?
Here is the list of the article:
l What should we pay attention to when choosing a candle cup?
l What should we pay attention to when I use scented candles for the first time?
l Are there any other considerations?
Different grades of raw materials, different weights, and different processes of glass are indeed heated differently. However, if it is a container for scented candles, related tests have generally been done during the development and design. If there is a burst, it will generally not be put into production, so the candle cups that can be put on the shelf are theoretically safe. It is best not to use drinking glasses, you can choose to go to a regular company to buy ceramic candle cups, glass candle cups or candle cups of other materials. Our company can supply high-quality candle cups for you.
To make scented candles burn beautifully, when burning for the first time, the candles on the surface layer must be completely melted to form a flat wax pool before being extinguished, so as to minimize the appearance of memory holes. Because the candle has a memory, if it is not burned according to the above method for the first time, every time it is burned to the place where it was extinguished, the candle will remember that place and will not burn out. After a long time, it will become an ugly Hole. Therefore, as long as the complete wax pool is burned out for the first time, the surface of the scented candle will be flat if you want to burn it in the future.
(1) Don't think that the candle wick will slowly turn to gray with the fire. It is necessary to trim the candle wick every time you light a candle. A long candle wick will cause the flame to be too high, and will accelerate the consumption of the candle. If the heating is not uniform, it will emit black smoke and blacken the candle wall. Trim the wick to 3 to 5 mm before lighting it.
(2) If the candle is blown out with the mouth, dense smoke will be produced. Special tools can be used to extinguish the candles. If not, you can also use stainless steel chopsticks or tweezers to gently poke the candle wick into the wax liquid. The flame will be extinguished immediately without producing smoke. Remember to straighten the candle wick.
(3) Do not use ordinary lighters to light candles, because it is easy to burn to your hand, and when the candle burns deeper, the lighter will generally not be able to reach it.
