Here's how to boil rosin:
Prepare ingredients: rosin, incense burner, medium-low heat, ventilation holes.
Cut and scrape the rosin: Cut the rosin from the pine tree and collect it for later use.
Cleaning the rosin: Put the collected rosin into the incense burner, bake the rosin over medium-low heat, and stir constantly so that the impurities and turpentine in the rosin are gradually released. After all the rosin is melted, filter out the impurities and turpentine.
Rosin boiling: Pour the filtered rosin liquid back into the incense burner and continue to boil over medium-low heat. Note that there should be a ventilation hole above the stove to allow the smoke to escape. Stir constantly during the boiling process to avoid rosin sticky bottom or bubbles.
Check the rosin: When the rosin liquid becomes thick and the color becomes darker, you can take a small piece of rosin and cool it to see if its hardness meets the requirements. If the hardness meets the requirements, the heat can be turned off. If the hardness is not enough, you can continue to boil.
Cooling and solidification: Pour the boiled rosin into the mold and cool and solidify.
Precautions: Master the heat: When boiling rosin, use medium and low heat to avoid excessive heat that causes rosin to paste the bottom or produce bubbles. At the same time, it should also be noted that the heat should not be too small, otherwise the rosin liquid cannot be fully heated, which will affect the quality.
Stirring: During the boiling process, the rosin liquid should be stirred constantly so that it can be heated evenly and avoid the bottom and bubbles. At the same time, it can also help the impurities and turpentine in the rosin to be released.
Filtration: When cleaning rosin, it is necessary to filter out impurities and turpentine so as not to affect the quality and taste of rosin.
Ventilation holes: Ventilation holes should be left above the stove to allow smoke to escape. If there are no air vents, smoke will accumulate in the furnace and affect the boiling effect of rosin.
Mold selection: When cooling and solidifying rosin, it is necessary to choose the appropriate mold. The mold should have a certain depth and width so that the rosin can be formed and taken out. At the same time, it is also necessary to pay attention to the cleanliness and hygiene of the mold to avoid polluting the rosin.
Storage: The made rosin can be stored in a cool, dry place, away from direct sunlight and high temperatures. At the same time, it is also necessary to pay attention to moisture-proof, dust-proof, insect-proof and other measures to ensure the quality and taste of rosin.
In general, boiling rosin needs to pay attention to the selection of materials, the control of heat, stirring, filtration, ventilation holes, mold selection and storage methods. Hygiene and safety should be maintained during the production process to avoid food contamination and the generation of harmful substances. At the same time, it is also necessary to pay attention to the appropriate consumption and storage methods, so as not to cause burden on the body and affect health.
