Jumping with overreach boots is generally allowed and commonly used to protect a horse's heels and pasterns from injuries caused by overreaching. However, it is important to ensure that the boots are properly fitted and do not restrict the horse's movement or cause discomfort. Some competitions may have specific rules regarding the use of overreach boots, so it is advisable to check the regulations before competing. **

No, overreach boots should not be used in the field. Overreach boots are designed to protect a horse's heels from being struck by their hind feet, typically during activities like jumping or dressage. In the field, horses are less likely to overreach and injure themselves in this way, so overreach boots are not necessary and may even hinder the horse's natural movement. It is important to assess the specific needs of the horse and the situation before deciding whether or not to use overreach boots. **

The closure of overreach boots should ideally be at the back of the leg. Placing the closure at the back helps to prevent interference with the horse's movement and reduces the risk of the closure getting caught on obstacles. Additionally, having the closure at the back ensures a secure fit and better protection for the heel bulbs and coronet band. Overall, the placement of the closure on overreach boots does matter, and the back of the leg is the most suitable location. **

A gas heater uses a spark to ignite the gas and create a flame. Once the gas is ignited, it continues to burn and produce heat without the need for a continuous spark. Therefore, after the initial spark, there is no need for it to remain lit as long as the gas is burning. This is why you may only see a spark when the gas heater is turned on, and not a continuous flame. **

To heat a plate over a candle flame, you can hold the plate above the flame at a safe distance to avoid direct contact with the flame. Move the plate back and forth over the flame to evenly distribute the heat. Be cautious not to hold the plate too close to the flame to prevent it from getting too hot or potentially breaking. **

No, ember is not hotter than fire. Ember is the glowing remains of a fire that has started to die down, whereas fire is the active, burning flames produced by a combustion reaction. Fire typically burns at a higher temperature than ember, as it is actively consuming fuel and releasing heat and light. **

An ember tetra is a small freshwater fish that is popular in the aquarium hobby. It is known for its vibrant red and orange coloration, resembling the glowing embers of a fire, hence its name. Ember tetras are peaceful and social fish that do well in community aquariums with other small, non-aggressive fish. They are relatively easy to care for and are a great choice for beginner fish keepers. **

Yes, a horse's blaze can change over time. A blaze is a white marking on a horse's face, and it can change in size, shape, or color as the horse grows and ages. Sometimes, a horse's blaze may become more pronounced or fade as the horse's coat changes with the seasons. Additionally, injuries or scars on the face can also alter the appearance of a horse's blaze. **
