Rosin pressing tips

Rosineer Ceramic Hot Knife is a heated cutting and loading tool that is designed to work with any type of concentrate, including the stickiest ones. Equipped with a ceramic heat element, the knife minimizes heating time and avoids overheating. It heats up in seconds after pressing the button and reaches a perfect temperature to scoop and drop your wax. The versatile tool uses a variable voltage battery which allows you to have multiple temperature settings. The knife's tip is removable for easy maintenance and cleaning. You can replace the battery part with a regular 510 one. The tool comes with a charging cable, a tip cover, and a case.

Note: Please read and follow the instructions when operating the hot knife.

Detailed Instructions:

  1. To turn on / turn off the knife, click button 5 times.
  2. You can adjust the heating temperature by clicking the button 3 times.  For the hottest (302 °F), the indicator flashes in red; for the hotter (248 °F), the indicator flashes in blue; for the regular hot (212 °F), the indicator flashes in green. Keep triple-clicking to go through all three temperature options.
  3. To start heating, just press the button and hold it while you are using the knife. Release the button, and the knife stops heating.
  4. For quick heating mode, turn on the knife (step 1) and then click the button twice. The knife will heat for 12 seconds and then automatically stop heating.

Rosin pressing tips

What is rosin and how it is produced?

Rosin is a concentrated extract of cannabis plant which is produced by applying heat and pressure to the plant parts (usually flowers or hash and kief) to squeeze out a translucent, sappy substance.

What do I need to start making rosin?
You need a rosin press, a parchment paper sheet, a collection tool, and your precursor. Additional items that you may want to use when pressing rosin are filter bags, pre-press molds, non-stick mats, etc.

How do I make rosin?

Prepare your plant material. Make sure it is kept at the optimal 62% humidity.

Place the plant in a folded parchment paper sheet.

Turn on your press machine and set your desired temperature and timer.

When the press plates reach the right temperature, place the parchment paper with your plant material on the bottom plate and operate the machine according.

When done, remove the parchment paper, get rid of the pressed plant parts, and gather rosin using your collection tool.

What are the recommended press settings?
For Cold Pressing: 160°F - 190°F, for 1 to 5 minutes or longer. Cold pressing produces terpene-rich rosin but with a sacrifice in yield.
For Hot Pressing: 190°F - 225°F, for 40 seconds to 3 minutes. The hotter you press, the higher yield you’ll get, but the high temperature causes a drop in rosin quality.
Flowers can be pressed at 190°F - 225°F for 30 - 180 seconds.
Refined precursors such as hash, kief, dry sift are usually pressed at 165°F - 195°F for 60 - 130 seconds.

What filter bags should I use?
We carry three mesh sizes: 25, 100, and 160 microns. 25 micron bags are best used with fine grain materials such as kief, bubble hash, and dry sift. 100 micron bags give the best filtration and highest quality output for flower rosin, but you may see some reduction in yield. 160 micron filters are usually the optimal type of bags for flowers; they result in good yield and quality rosin. For detailed info on filter bags, please see FAQ on How To Select Rosin Filter Bags

Excellent Tool

It has exceeded expectations. If you are on the fence about this, go for it! Much better price compared to others and works very well.

A heat pen scoop

The battery works well no issues there. Hols a decent charge and works as it should.
The scoop though a great design lacks heating at the tip. The rest of the shaft will get hot and can burn you before the tip gets hot enough to slide off the product. By that point, you have a few seconds before you start to burn your product. Better heating to the tip would definitely help fix the issue you have and make this an awesome heat scoop.

Good and all, but I think the 510 threaded knives honestly operate better!

Warm knife with nice contours

This device has nice contours for scooping dry dabs like diamonds or sugar. It your dab is sticky, however, this isn't the tool for you. Even at it's highest setting, the blade doesn't get hot enough to move the wax. My readings show it barely got to 150F, which is basically useless as a hot knife. Not recommended.

love this thing

works great, love the shape of the scoop
