Melting Point
Melting Point
If by melting you mean changing into liquid, it does, but for a few moments. It again turns back into the shape of the mold. It does not melt as a liquid but softens as it flows when heated. When it becomes soft it can be molded into any desired shape.
The melting temperature of glass depends on the composition of glass, moisture in glass content, and type of glass. Glass is molded at the temperature of 1400C to 1600C (2552-2912F). When heating, It liquifies a bit and the rest of the glass remains solid.
After melting, the liquid attains the shape of the mold in which it is poured. Glass passes through the softening stage before transitioning to a rubbery texture. In its melted form, it looks waxy. Once cooled quickly, it can break easily.
OK, so: glass does not melt. It liquifies and becomes softened gradually when heated. The temperature when glass actually turns into liquid depends on the composition of glass.
What is the melting point of glass? Glass liquifies or melts at high temperatures from 1400C to 1600C. This temperature varies with the composition of glass. As glass is made up of different substances like lime, soda, and sand. Moreover, different types of glasses have different melting points.
Borosilicate glass aka hard glass, melts at a high temperature of about 3000F or 1648C.
Soda Lime Glass melts easily at a relatively lower temperature than hard glass. It melts at 1000 degrees Celsius. Whereas it turns into vapors around 3427-degree celsius.
Quartz glass is relatively harder as it is mineral, not glass. It has a melting point of 1250 degrees celsius. Due to its brittle texture, it requires a high temperature to melt.
Pyrex is borosilicate hard glass. This makes it highly temperature resistant. It is widely used in the manufacturing of kitchenware that we use in the microwave. The melting point of type 7740 Pyrex is 1,510°F or 820°C.
empered glass is the toughest type of glass and is not easy to break. It has wide application for safety purposes. It is manufactured by heating and then cooling readily. That’s why it has a different structure and breaks differently.
Tempered glass melts between 1100 and 1300 degrees Fahrenheit. After heating, it is cooled readily using high-pressure cold air. After cooling, it hardens under stress. When it breaks it turns into Peebles rather than splinters. It needs four times more force to break it than needed for untreated glass.
Lead glass is not easy to melt. A temperature between 1350 degrees Celcius to 1500 degrees Celcius is required to melt this glass. This procedure is carried out in an electric furnace where it undergoes heat and electricity.
The melting point of glass wool (fiberglass) is 1450 degrees Celsius. After melting it is passed through spinners where it is turned into glass fibers. These glass fibers are mixed with plastic and have wide applications in synthetic items.
Overall the softening temperature of glass ranges from 140 degrees Celcius to 370degree Celcius. It varies with the type of glass and moisture content in its composition. When it gets softened, it turns from a solid state to a soft rubbery state. This temperature is lower than the melting point of glass.

Care Instructions
Care Instructions
We've spent a lot of time and effort to create the perfect design for your products — it's important that you know how to take care of them in the best way possible!
Printed apparel (direct-to-garment)
We use the latest direct-to-garment (DTG) printing technology to offer a wide variety of printable garments and design color options. We use high-quality inks that won't fade for a long time if taken care of properly.
Keep in mind that the original manufacturer's care instructions don't take into consideration the DTG printing process. So we suggest following the care instructions on this page to learn how to take care of your printed garments properly.
Printed apparel can be machine-washed cold, inside-out on a gentle cycle with a mild detergent and like colors. Use non-chlorine bleach only when necessary. You shouldn't use any fabric softeners or dry-clean the items.
DTG-printed apparel can be tumble-dried on a low cycle, but hang-dry works best. When it comes to ironing, use cool iron inside-out. Don't iron the print.
Follow these instructions carefully to avoid fading and cracking of the print, and shrinking the garment that can occur if you wash or dry it on a high setting.
Embroidered apparel
Embroidered apparel can be machine-washed cold, inside-out on a gentle cycle with a mild detergent and like colors. You can use a small amount of chlorine bleach, but non-chlorine is the safer option.
If you notice any color residue in water, rinse the garment in lukewarm water and then in cold several times, but try not to rub any stained embroidery. Embroidered clothing can also be dry-cleaned.
After washing, don't leave the clothing to soak or lie in a pile while wet. Don't wring out the embroidered items, but if you want to tumble-dry them, use a cool air setting.
If the garment needs ironing, do it inside-out, preferably between two pieces of cloth. You shouldn't wet embroidery before ironing or use a steam iron.
Embroidered hats, backpacks, and shoes
Embroidered hats, backpacks, and shoes can be wiped clean with a damp cloth in the spots where it’s needed. If necessary, hats and shoes can be hand-washed cold. Don’t use brushes.
All three products can’t be machine-washed, bleached, tumble-dried, ironed, or dry-cleaned. Read the manufacturer label carefully for any other instructions.
Embroidered aprons
Embroidered aprons can be machine-washed at 86ºF (30ºC) or less. Don't use bleach. They can be tumble-dried on a low cycle. Read the manufacturer label carefully for any other instructions.
All-over printed apparel, hats, fabric, and swimwear
All-over printed apparel and fabrics can be machine-washed cold with like colors, without bleach. Don’t dry-clean or tumble-dry the apparel. You can iron it with a low heat setting.
All-Over Print Face Masks
All-Over Print Face Masks can be machine-washed at 140ºF (60ºC) with like colors, without bleach. They can't be dry-cleaned. You can tumble-dry the face masks on low heat and iron on a cool setting.
Bags
All-over print backpacks, fanny packs, and duffle bags need to be hand-washed without bleach. Don’t dry-clean or tumble-dry the bags. You can iron these bags with a low heat setting.
All-over print totes and drawstring bags can be machine-washed without bleach on a cold cycle. They can't be tumble-dried or dry-cleaned. You can iron these bags with a low heat setting.
Pillows and pillow cases
Pillow cases can be machine-washed without bleach on a cold cycle. Don’t dry-clean or tumble-dry the pillow cases. You can iron them with a low heat setting.

Sublimation socks, blankets, towels, and laptop sleeves
Sublimation socks, blankets, towels, and laptop sleeves can be machine-washed cold with like colors at no more than 86ºF (30ºC). Don't use bleach and don't dry-clean. It's best to hang-dry, but tumble-drying can be used on a low cycle if necessary.
Sublimation flip flops
Sublimation flip flops can be hand-washed in warm water with a mild neutral detergent.
Mugs
Our White Glossy Mugs and White Ceramic Mugs with Color Inside are microwave and dishwasher safe, but the print and coating will last longer if you hand-wash them.
Matte Black and Glossy Black Magic Mugs, however, should only be hand-washed, and you can't put them in a microwave. Note that they're also prone to scratches, so be extra careful.
The same goes for our Enamel Mugs that should only be hand-washed. Also, you can't heat liquids or food directly in the Enamel Mugs—it can damage their coating.
Posters and Canvas
To ensure that your posters and canvas last for a long time, don’t keep them in direct sunlight or outdoors. They can be gently dusted with a soft dry cloth or a feather duster.
Phone Cases
To clean a phone case, remove the case from your phone. Add a little mild soap to water, and dampen a cloth or sponge with it. With the damp cloth, rub your case gently in circles. Let your case air-dry at room temperature.
Don’t clean your phone case with any alcohol-based products as they can remove the ink and discolor the case.
Jewelry
Don't wear the jewelry while showering, swimming, washing dishes, applying perfume or doing sports. When not wearing it, store it in the box you received it in.
After wearing the jewelry, we recommend wiping it with a non-abrasive jewelry polishing cloth to remove dirt and tarnish. But to fully remove tarnish and any stains on the jewelry, use silver or jewelry polish. Follow the instructions on the bottle carefully and use gloves when working with silver polish.
Stainless Steel Water Bottle
Hand-wash only (dishwasher not recommended due to vacuum seal).
