Fast forward to today and modern manufacturers no longer include such metal cone formers. Customers are forced to either burn incense powder on charcoal, which is kind of silly since the powder itself is self-lighting and shouldn't require charcoal to burn. Another way customers have fashioned cones is to for a small funnel out of paper. However, using paper can be difficult and often creates inconsistent incense cones.
I'm going to share with my readers a trick they can still take advantage of.
Go on eBay. Search for "Vantines Incense" and pick one a listing that comes with a metal cone former. You should be able to get one for around $20 or under. These metal cone formers are sturdy and should last you the rest of your life. You should only need to purchase one but you can purchase more to have as back-up in case you misplace them or they become damaged. I currently have two and am thinking of purchasing more.
Not only will you have a metal cone former to use in your rites but you can also have a vintage metal incense tin that you use for decoration or even to store modern incense powders. If you lucky then your tin will come with some ancient incense powders still in the tin!
The picture below is one Vantine's tin I purchased with it's metal cone former and a cone of incense on a glass candle holder. The tin was manufactured sometime in the 1930 and still had some brownish-green incense powder in it. It's remarkable to think that the incense it contained is nearly 90 years old! Of course it has long lost any pine fragrance it once contained.
