Consumer Version of the Nishiki Kamuro Effect

Yung Fang makes a fantastic professional Nishiki Kamuro - I've seen it several times over the years, including in Montreal for Team Canada's performance in 2010 I think.
There was some talk about Mystical getting some Yung Fang items approved for use in Canada, this was back when the Symposium was in Changsha, China, think 2013. It would seem that never came to fruition but I really was looking forward to having Nishiki's in our approved items

Yung Feng does not make consumer fireworks. They are one of best display shell factories in China. They are a Taiwanese company that makes display shells by traditional Japanese shell manufacturing procedures.

Nishiki Kamuro translates to Brocade Sacred Room. A Nishiki Kamuro is a Brocade Crown which is a common Display shell Effect. The reason Nishiki Kamuros are very good (aside from the cool sounding name) is the companies that use the name are usually supplying a high quality Brocade Crown.

The problem with getting the same effect as the video is that USA consumer products can have 60 grams powder weight in a mortar shell. They can use 60 gram shells in 500 gram cakes. Canada allows 25 grams powder weight in a consumer mortar shell and 8 grams powder weight in a cake tube. So the stars can't be big enough to give the burn time you see in the video posted by Smile.

The company that Authorized a cake would be able to tell you the powder weight of the cake. I would give that info to customers to on request (I only import display fireworks). You could request that info from the companies that have authorized consumer fireworks but it would be up to them if they wanted to supply the info.

Also yes generally more powder = Better

When you see 200 gram and 500 gram cakes in the USA that only means they fit into that regulated load range. 200 gram cakes are any cake with 200 grams or less powder and 500 gram cakes are any cake with more than 200 grams up to 500 grams. The regulation requires that any cake with more than 200 grams and tubes with an ID greater than 1/2" have the tubes separated by at least 1/2" and all cakes with more than 200 grams require an attached base for stability.

Closest to this effect would be a long way off. You can't get the duration with consumer fireworks size stars. The closest would be a brocade cake firing a row at a time or many Brocade mortars fired in quickly one after the other to maintain the brocade effect in the sky. There are several consumer fireworks with the brocade effect.

Tube size is inside diameter, outside diameter and length.

That is probably about as good a brocade consumer cake as you could get in Canada. I am assuming from the video that the gold in the brocade was not shown in the video very well. That is common for the silver to show well and the gold to be almost invisible in a fireworks video.

Does tube size matter when the variations in the larger cakes are so small? Say for example there is 8 grams in a 20mm tube and 8 grams in a 22mm tube. What would the difference in performance be (if there is any)?
