Can they be used in a gun cabinet

Yes. All silica gel beads and packets work in an air-tight seal container. If they are open to air, they are constantly absorbing moisture in open air and become saturated right away. Please, keep them tight sealed as much as possible. Information below lets you estimate how many grams of silica gel is needed at a given volume of your container. This is a general estimate when used in an air-tight sealed container. The amount of silica gel needed will depend on several factors: 1. Chemical properties of the product that will be used: 2. Volume of the container 3. Conditions and physical properties of the container Container volume – packet size 600 cubic inch - 5 gram 5 gallon bucket - 10 gram 2 cubic feet - 30 gram 4 cubic feet - 60 gram 8 cubic feet - 120 gram We always recommend placing extra packets than recommended to cover the factors mentioned above and for extra protection. For your use, we would recommend using our pre-made packets for easier use and reactivation. When you buy loose beads, you will need to place the beads in a breathable bag like organza bag or muslin bag. When it's time for reactivation, you will need to remove the beads from the bag to reactivate them and place them in the bag again. With pre-made packets, you can use them as packets and reactivate the whole packets. We would like to recommend our special packets. Special packets are food safe and you can use them for non-food uses too. They are semi-transparent and contain a mixture of white beads and orange beads. White beads tested the best in performance compared with colored beads. These packets have the benefit of highest performing white beads with few orange beads to serve as an indicator. Orange beads will change to dark green when saturated. Also, the packet material is very sturdy so that you can reactivate in any mode in the microwave (even high power). This Special Packet is the only packet in the silica gel industry that is food safe, indicating, and rechargeable via both oven and microwave. Available sizes are 20, 50, 100, and 500 gram. You can choose the packet size based on the volume of your gun cabinet. Below are the links for 50, 100, and 500 gram special packets. https://www.amazon.com/Dry-Premium-Quality-Indicating-Packets/dp/B07K4PRGZ6/ref=sr_1_32?dchild=1&keywords=50%2Bgram%2Bspecial%2Bpackets&qid=1612394776&sr=8-32&th=1 https://www.amazon.com/Dry-Silica-Indicating-Packets-Desiccant/dp/B082RJ1NJ1/ref=sr_1_2?dchild=1&keywords=100%2Bgram%2Bspecial%2Bpackets&qid=1612394936&sr=8-2&th=1 https://www.amazon.com/Dry-Orange-Indicating-Packets-Dehumidifier/dp/B083B8JM3J/ref=sr_1_4?dchild=1&keywords=500%2Bgram%2Bspecial%2Bpackets&qid=1612394962&sr=8-4&th=1 Thank you.

Since these don't change color when they need to be reactivated, is there a general amount of time they should be considered "spent"?

You can use the weight method. If there's an increase up to 30% of its original weight, you can recharge/reactivate the beads. You need to weigh the beads before using them. For example, you can weigh 300 gram of the beads. If the beads weigh 390 gram after use, it's time to replace or reactivate them. Thank you.

Do these change color when they are saturated to tell you when they should be reactivated?

Silica gel beads are white in nature. White beads tested the best in performance compared with colored beads. However, you can't tell when they are saturated with moisture with white beads. If you would like indicating beads, we do carry blue to pink or orange to green beads. You can type B013L2Z2MY or B01I5Y9H6A in Amazon search bar for 1 gallon blue or orange indicating beads. Thank you.

How much will I need to dry my wedding flower bouquet

We would suggest using our loose finer type of silica gel beads for drying flower. You need to completely soak the flowers with the beads. Also, be very gentle when you soak the flowers with the silica gel beads and when you remove the flowers after they are dried not to break them. You can type ASIN B07QR7K2ML on Amazon search bar or go to the link below. https://www.amazon.com/dp/B07QR7K2ML?ref=myi_title_dp Thank you.
